Ammonia Gas Leak Detector Some users prefer to use a few 0-500 ppm sensors, as levels at or above the IDLH (300 ppm) will be indicated, and appropriate clothing and respirators can be selected by the emergency response team.An LEL sensor is often used in enclosed areas where there may be potential for a large Ammonia release and concentrations approaching the LEL (15%).Mounting configurations for the gas sensors include placing the sensor remote from the transmitter, or drawing a sample from a remote or inaccessible location.The latter must include a flow switch to indicate sample system integrity.A special calibration adapter is supplied for the remote sensor option, so that calibration functions can be performed from the transmitter location.Electro-chemical sensors have temperature limitations, which should be observed, or useful life will be compromised.Advanced organic Ammonia sensors, function over a range of 4 to 122 F (20 to 50C), but may fail in high humidity and high temperature. Heat shields are used to protect the sensor-transmitters from radiant heat off the flue work.
