  • The Honeywell Analytics Sensepoint XCD Combustible Gas Detector with remote monitoring capabilities for Infrared and Catalytic Bead sensors. Its remote capability is designed to deliver installation flexibility and is an ideal solution for any application where the transmitter requires separation from the sensor.  Example applications: where the point of detection is in an area not easily accessible, where the sensor is not visible ie. in high or low level concealed areas, or outside of an enclosed process area that’s being monitored.

    Sensepoint XCD has been designed for ease-of-use. Users can modify detector operation using the LCD and magnet switches without ever needing to open the unit. This enables one-man, non-intrusive operation and reduces routine maintenance time and costs. A tri-color backlit LCD clearly indicates the unit’s status at a glance, even from a distance in bright sun. A steady green backlight indicates normal operation, flashing yellow indicates fault, and flashing red indicates an alarm.
