Choose Sample Tubing Wisely for Gas Monitors in San Jose, CA

There are many considerations for sample tubing for your gas monitors in San Jose, CA. Teflon-based tubing is the best option because it will reduce the chance of contamination and sample loss caused by absorption. This allows for improved gas detection and fewer industrial incidents. It is generally the best quality tubing you can purchase. Here are five reasons why you should seek Teflon-based tubing:

  • Non-reactive: Chemical reactions are possible in the process of gas monitoring. Some tubing types are very reactive to certain gases and elements in a monitor. Silicone rubber tubing, for example, should never be used with gas monitors that use the catalytic bead combustible gas sensor. It will actually create additional poisonous gas, which creates a new problem while you are attempting to detect and correct another one. Teflon-based or Teflon-lined PVC material does not react to other gases in this way. You are assured a clean environment as you monitor and collect data.
  • Better material for portable devices: You will find Teflon materials in portable monitors because it stands up to different conditions. The monitor can be jostled or exposed to the most toxic elements and it will still function at admirable levels. You are not guaranteed this durability with other materials because of the reactive elements and other sensitivities. Teflon is also preferred for remote access devices because its durability requires less hands-on intervention to assure it works.
  • Good moisture resistance: Polyurethane-based tubing is sensitive to moisture. This can reduce detection in humid environments and corrode the device. Teflon is resistant to this condition, and as a result your monitor will function better with better readings. Sample tubing is vulnerable to condensation, but so are the electronic functions within the monitoring device. Use Teflon to keep this element under control for improved monitoring.
  • More accurate data: When you go with quality, you also produce better data. Since Teflon is resistant to many elements that make the sampling process challenging, you will have a better idea of what is going on with your gas monitoring and detection. You will not make upgrades based on bad data, and you will find problems before they become too serious. Accurate data is not only good for assuring safety and controlling gas leaks, but also for letting you know when it is time to adjust or change your equipment. You can rest well knowing your data is accurate.
  • Fewer contingencies: Gas monitoring needs to occur efficiently, and if workers are constantly managing the sample tubing, that is not going to work out. Choosing the best materials for the job makes the process easier because fewer processes can go wrong. There is no need to second guess results or worry that the wrong tubing just produced poisonous fumes. More time is spent testing and analyzing, rather than fussing over the equipment.

Choose Programmable Gas Detectors in San Jose, CA Over Spec Controllers

A Programmable Logic Controller (PLC) monitors input devices and adjusts systems based on the data it collects. The PLC became an essential part of gas detectors in San Jose, CA over the years and this has made businesses safer and able to operate more smoothly. There is confusion sometimes because gas detectors also come with spec controllers provided by the manufacturer. Here is why a custom PLC setup is a better option over the spec controller:

  • Remote access: You do not have to be on site to access the PLC. Many models can be programmed using text messaging or email. They can also provide an alarm through remote means, and that allows the staff member on call to make the needed adjustments, often needing only their smart phone. Less travel time for workers saves you costs and allows for issues to be solved quickly. Many industries realize the cost savings and convenience of remote access, and those advantages are available in gas detection, too.
  • Easily operated: While you still require specialized professionals to operate the PLC, many people in those sectors find the PLC to be a preferred choice. The main reason is its universal nature. There is no need to constantly switch out controllers because an upgrade also means a change of manufacturer. It only needs adjustment to the new system, and you are once again good to go.
  • Better sensors: PLC devices pick up on gas leaks before they become a serious problem. You no longer wait until employees complain of nausea or headaches, and it allows more lead time to solve the problem or evacuate the premises. This creates a safer work environment, which also reduces your overall costs.
  • Direct software access: Many industries use the Supervisory Control and Data Access (SCDA) system. This advanced design uses computers, networks, data communication and graphic interface to manage processes. Peripheral tools like logical and PID controllers offer additional opportunities to make accurate adjustments. The PLC accesses this system directly, so changes can be made quicker and, again, remotely. It operates in real time, so if a gas leak or other emergency arises, solutions occur quicker than if they relied solely on human intervention. In non-emergency situations, it also allows for changes needed for efficiency and good functioning.
  • Expands possibilities: SCDA developed as a universal system for allowing remote access to several types of control modules. These systems work across manufacturing brands and industries. It allows for better system integration than anything that was possible before. When you have PLC and SCDA intertwined, you not only have an efficient system, but one that easily expands. Today’s industries are about adjusting to current demands, and the spec controller does not have the same ability to work with multiple brands. Your systems will be as simple or complex as they need to be.

An Overview of False Alarms in Toxic Gas Detection Systems in San Jose, CA

Gas detection systems in San Jose, CA are designed to pick up on potential toxic gas leaks to keep every person in your facility safe, which is why it’s crucial that you have the right gas detection device in place. This is not only because hazardous gases have the power to knock out an entire workforce, but because many are also flammable. From gas poisoning to fires and explosions, gas detection alarms must be taken seriously, no matter what—including false alarms. But even though the alarms might be false, you cannot allow employees to stop reacting to them.

As a reminder to everyone working in your facility, here’s an overview of false alarms produced by toxic gas detection systems in San Jose, CA.

What is a false alarm?

We’ve all probably encountered a false alarm either at home or at our place of employment. The most common type of false alarm is the smoke detector going off. That loud beeping is meant to be annoying in order to alert you to the presence of smoke, but when you don’t see smoke, you may go looking for a source that’s not there. False alarms lead to panic, and in an office building or factory, it’s likely to bring out the fire department.

But for your facility that’s around any number of gases, alarms—though they may be false—can be extremely scary. A toxic gas detector is a device installed to alert everyone on site that a dangerous level of a specific hazardous gas has been detected; in some instances, that gas is not actually loose in the air.

Main causes of false alarms

  • Your gas detector could be reacting to a certain hazardous gas, which may create an electrical noise or signal that leads to a false alarm. This is also known as cross-sensitivities caused by a chemical reaction.
  • Maintaining your gas detection system plays a huge role in whether or not false alarms occur—especially since sensors can lose their sensitivity after a certain amount of time. This means they are more likely to malfunction and produce false alarms on a regular basis before completely dying off. Depending on the manufacturer, sensor life is typically 6 to 24 months, but with scheduled maintenance services, you can have them replaced well before they start losing their accuracy.
  • Another possible cause of false alarms in your facility is the age of the detection device. Old technology and equipment may have proven worthy for a good length of time, but you want to consider replacing your old system with a newer, more efficient one to stop nonsensical alerts and to ensure workplace safety.

When you own one of many gas detection systems in San Jose, CA, you are responsible for keeping it maintained. Your employees depend on you to keep them safe at the workplace, which is why you should schedule regular system maintenance and sensor checks with the experienced team at MDC Systems, Inc.

Basic Principles and Factors to Keep in Mind with Sensor Placement for Area Gas Detectors in San Jose, CA

When it comes to commercial gas detection system installations, it’s important that you first schedule a professional risk evaluation for potential gas hazards and equipment selection and placement. Where you place your gas sensors is crucial if they are to do their job, as it helps to ensure that everyone in the building is safe from exposure to toxic or combustible gases. But before we take a look at some of the basic principles and factors of sensor placement for area gas detectors in San Jose, CA, let’s briefly discuss the risk analysis process.

Analysis of risks

You want to install the best gas detection system from the start, so make sure to call a company skilled in the industry. A professional will be able to recommend the most efficient detection equipment for your needs, as well as where to place the sensors.

The analysis process is likely to include inspecting areas for potential sources of gas leaks. Not only will this indicate where sensors should be placed, but it’s also good for you to know if you need parts replacement or repairs. They may also check the density and other properties that make up the gas you work around to aid in the placement process. Undoubtedly, there are a few things that can affect the direction and rate in which gas diffuses during a leak. For this reason, these factors need to be pinpointed.

Furthermore, whether you already have a system installed or are planning to do so in the future, the environment where the detector resides should have its own evaluation performed to make sure it’s the right product for your space. This includes testing the temperature, checking for nearby vibration, ensuring adequate ventilation and inspecting the cleanliness of the environment.

Principles and factors

The following important points should be kept in mind:

  • Sensor placement for area detection is based on many factors, such as the weight of the gas, vapor density, the device’s ability to alert workers and being capable of holding up in the event of an explosion.
  • Factoring in the vapor density of all monitored gases is important, which is why you need to bring in a gas detection expert.
  • The risk analysis will show the areas most susceptible to a possible gas leak. Placing sensors close to gas sources and possible leaks makes sense.
  • Place sensors in spots where the air is likely to collect a high concentration of gas. Potential areas include stairwells and crawlspaces, but also areas where gas can easily build up in corners or around machines or devices that release gas.
  • It may seem like a good idea to place sensors near air vents. Unfortunately, vents act as channels and can endanger more areas in your building or nearby buildings should a gas leak occur. And because of air dilution, detectors placed too close to vents can cause issues with gas samples.

These are just a few of the factors to be aware of. But luckily for you, MDC Systems, Inc. is here to assist with selecting the right system design, as well as to help with the placement of commercial building gas detectors in San Jose, CA. Feel free to contact us with any questions.

Looking Into Gas Detection Systems in San Jose, CA? Consider the Lifetime Cost of Ownership

As the owner or landlord of a sizable commercial building, it’s important that you ensure the safety of everyone inside. More specifically, we’re talking about installing reliable gas detection systems in San Jose, CA to alert you to dangerous gas leaks. Starting with an evaluation to determine specifications, you will want to choose wisely—in other words, keep in mind not only the initial cost of the system, but also the cost of ongoing maintenance throughout the years. Get an inadequate unit and you may be looking at regular service calls to determine problems—or worse, it may malfunction when a leak occurs.

That being said, it’s imperative that you select the right gas detection system not only for function, but also because doing so can save you thousands of dollars over the years. Here are some of the things you want to consider when thinking about the lifetime cost of ownership.

The warranty period

Like a warranty you get for the large appliances in your home or for the industrial grade systems that keep your business building running, you will want to make sure your gas detection system is also covered under a warranty. Should something break or the system act up, a good warranty should take care of the cost (or most of the cost) of repairs and replacements. And the warranty period is just as important as what parts and services are covered to give you peace of mind. Therefore, consider the warranty in conjunction with the purchase price.

Component replacement

It’s important that you know what it will cost to replace major components on different gas detection systems in San Jose, CA. The technology—like sensors and connectors—will vary depending on the type of gas detector. For example, a pellistor-based sensor is less expensive, but since it typically has a shorter life, maintenance and replacement costs are higher. Meanwhile, a part that is predicted to go out in a short amount of time is probably not going to be covered under a warranty for long.

Features and design

Of course it’s a good guess that a cheaply made system will fall victim to all sorts of issues, not to mention the need to replace it sooner. And the parts that are more susceptible to damage—like unit covers and buttons or knobs—might not be written into your warranty. When you select a gas detector system that’s designed to last with strong and undated technology, you can save on maintenance and replacement costs over its lifetime.

Ultimately, once you realize why it’s important to consider the long-term cost of ownership—maintenance, warranty, repairs and replacements—then safety should become the top priority. So avoid the temptation to buy a gas detector solely based on a low price tag. Talk with a reputable gas detection expert to learn about each system that would work best for your industrial or commercial building.
