QTS-1710

Combustible Sensor Series

The QTS-1710 Series utilizes catalytic pellistor bead technology for the measurement of combustible
gases. The standard sensor is resistant to poisoning substances such as silicones, sulfur compounds,
and chlorinated compounds. It is mounted in an explosion-proof housing, which is rated Class 1,
Division 1, Groups A, B, C, and D. The transmitter provides a 4-20 mA output linear to the LEL (Lower
Explosive Limit) of the calibrated combustible gas. The analog transmitter operates on a power supply
of 12-30 VDC in a three wire configuration, and is also mounted in an explosion-proof housing, rated
Class 1, Division 1, Groups B, C and D. Test jacks are provided to monitor the transmitter signal
without interrupting the output. All transmitters are calibrated using a correlation method with
Methane calibration gas and detection constants as shown. Calibration with actual target gas is
available upon special request; use “S” for special calibration in the options section of the ordering grid.
