CX Series Fixed Gas Detector

GAS MONITOR FOR HAZARDOUS & CLASSIFIED LOCATIONS

Conspec’s CX Series is your fixed gas detector solution for toxic or combustible gas monitoring in hazardous or classified locations. The CX Series is available with an analog 4-20 mA output, dry relay contacts, & Modbus RTU over RS-485 communications.

The CX Series fixed gas detector supports over 35 sensor types giving it the capability to detect over 100 different gases. An optional remote sensor can be placed in potentially harmful areas while the transmitter can be monitored safely. Dry contact relays for 1st level alarm, 2nd level alarm, and fault can be used for alarming or process control. The 4-20 mA analog output signal or optional Modbus RS-485 communications can be connected to any existing PLC, DCS, or EMS system.
