Very sensitive to flammable gases such as carbon monoxide or natural gas, catalytic sensors alert nearby workers of impending danger very quickly. Because of this, they are considered very useful in almost any type of work environment. However, as with virtually all types of flammable gas detection systems, catalytic sensors do have some limitations that can alter their performance. Though considered extremely accurate and reliable, it’s best to know all you can about these sensors before installing them at your facility. Since there are many aspects of these sensors that work together to result in their accuracy and reliability, it’s important to understand what goes into making a successful catalytic sensor.

Long Lifespan

When choosing flammable gas detectors, always look to those that are proven to last a long time. Not only are they very reliable, but they will also save your business much money in terms of replacement costs. In addition, they can also be calibrated so that they can detect those gases that infrared sensors cannot, making them even more reliable.

Be Aware of Placement

When using catalytic sensors to detect flammable gas, always give careful consideration to the areas in which they will be placed. Although known to do well in extremely harsh work environments where high temperatures and humidity levels are common, they can at times have performance problems if placed in areas where they are exposed to hydrocarbons for long periods of time. When this happens, the sensors are damaged, leading to weak signals or no signals at all being transmitted.

Contamination Issues

Along with making sure you use catalytic sensors in a proper work environment, it’s also crucial to ensure they don’t become contaminated due to exposure to certain chemicals. For example, since these sensors can become contaminated from silicone and chlorine compounds, the result can be the sensors becoming inactive. If this happens, the risk for fires and explosions greatly increases, since the detection levels will be very low at best. To keep this from happening, always make sure maintenance technicians or engineers regularly test the sensors by exposing them to limited quantities of certain gases, which will keep them active as well as accurate.

Positioning Your Sensors

When it comes to flameable gas detection, properly positioning your sensors is key to success. For optimal performance, position the sensors where they will experience little or no shock or vibration. By avoiding these hazards, the circuitry of the sensors will not be damaged, which if happens results in false readings. To ensure greater safety and accuracy, many companies choose to invest in portable flammable gas detectors, which workers can carry with them no matter where they go in a facility.

While there are many do’s and don’ts that go into having catalytic sensors that offer accuracy and reliability on a daily basis, it’s crucial to pay attention to the smallest of details to maintain high levels of safety.
