Page 13: Tools And Test
TX6386 • TX6387 User Manual Discrimination Catalytic combustion sensors can detect a wide range of flammable gases but they cannot discriminate between individual gases. They will respond to most, or all, of the flammable components present in the atmosphere without distinguishing between them. -
Page 14: Siting Recommendations
A very important part of an efficient gas monitoring system is the training of plant personnel in operation and maintenance of the sensors and the complete monitoring system. Training can be provided by qualified Trolex application engineers. Once a sensor installation is complete, the sensor locations and types should be formally recorded and a planned test and maintenance procedure instituted. -
