Abstract: Automotive NOx sensors are primarily of the amperometric type, with two or three electrochemical cells in adjacent first cell electrochemically pumps O 2 out of the sample so it does not interfere with the NOx measurement in the second cell. Commercial sensors, available from several suppliers, are used for the control of NOx adsorber and SCR aftertreatment.
Highrange sensor at a lowrange price. The GGNH32% is designed to detect and monitor potentially explosive levels of ammonia vapors in the event of a catastrophic failure. Codes specify an electrical shunttrip of the mechanical room at a level not higher than 25% LEL to remove potential ignition sources in the event of a serious ammonia leak. The GGNH32% allows for an earlier trip ...
