Model SA2-CPS (NON-SELECTIVE COMBUSTIBLE GASES)

Smart Sensor Modules

Model SA2-CPS smart sensor modules are designed to detect and monitor combustible gases in ambient air. The modules consist of a target gas specific pair of catalytic pellistors and a micro-processor-based signal conditioning circuit. The signal conditioning circuit includes advanced detection analytics. Both are housed in a metallic enclosure fitted with gold plated connecting pins.

Alarm Point Configuration

"The Smart Sensor Module" is factory programmed for a specific range of sensitivity. On power up, gas type, measurement range, and previous zero and span calibration data points are read by the transmitter, facilitating a fully automated startup. When used with any Safeguard Analytics gas detection transmitter, calibration may be performed on site or remotely, and the module transported to the point of installation pre-calibrated and ready for operation.
