EX-5165 Infrared Carbon Dioxide Sensor

Remote Gas Monitoring Sensor Transmitter with Infrared Sensor Transmitter for Carbon Dioxide, CO2

EX-5165 remote gas monitoring sensor transmitter incorporates a miniature NDIR type sensor for the measurement of carbon dioxide concentrations ranging from 500 ppm to 100% by volume.The sensor is comprised of dual pyroelectric detectors, one active and one reference unit, with individual optical filters for specific radiation bands. Features of the sensor include a temperature monitor and a durable tungsten filament as the IR light source.This sensor transmitter can operate in anaerobic atmospheres, provides longterm stability and requires minimal maintenance.

The EX-5165 sensor transmitter operates on 24 VDC power and features three LED alarm point indicators and 4-20 mA output.This sensor transmitter can be connected to various single and multi-channel ENMET controllers or computer-based instrumentation, such as PLCs, SCADs, BMSs, etc.
