When looking for a gas monitoring system you must address 5 key concerns:
1. Proper selection of sensor technology
2. Accuracy of readings
3. Speed of response
Although several different types of sensors are employed as LFL monitors, each has an appropriate application to which it is best suited. Fires and explosions in what was thought to be “protected” equipment can occur without warning when a sensor is not capable of doing the job that had been assigned to it. This is most often caused by a misunderstanding of the different available technologies.
Choosing the right kind of instrument can be a detailed task, even for those familiar with the process. The instrument of choice may vary from one application to the next, but the correct one should perform accurately under the demands of the industrial environment, avoiding unnecessary downtime and frequent maintenance. It should also have a fast response time and in most cases, be able to read a wide range of flammable substances.
