The cost saving initiatives could mean a compromise to process safety if toxic gas leaks undetected. It is important to know that a degraded electrochemical sensor will not give any indication or fault warning and the performance of the gas sensor could be questionable if the users choose to use the sensor for an extended period beyond the recommended sensor replacement cycle. Shorter sensor replacement interval means higher rate of sensor degradation.Įlectrochemical sensors are primarily designed for detecting toxic gases.
The sensor replacement interval varies among different manufacturers and it is important for the asset owner to be aware and plan for the preventive maintenance. All gas sensors comes with a service life span and shelf life which requires periodic calibration and sensor replacement. Each gas detector comes with a gas sensor which is very specific for toxic gases or combustible gases. The asset owners are always striving to establish a balance between the maintenance cost and optimum levels of process safety. They are used extensively in industries to protect personnel and equipments from hazardous gases.
Gas detectors separate the plant operators and assets from catastrophes.
