421-7786: NH3 Sensor Assembly

Description:The NH3 (ammonia) sensor monitors levels in the exhaust so an onboard computer can regulate the air/fuel mixture to reduce emissions. The sensor is typically mounted in, or behind the exhaust manifold(s). It generates a voltage signal proportional to the amount of ammonia in the exhaust.Attributes:• Real time measurement of NH3 levels• Active analog outputApplications:• Industrial engines• Cat exhaust sensors are application specific sensors, consult your owners manual or contact your local Cat Dealer for more information.
