This version of the Pro CO Alarm analyzer detects:
(1) CO in air flow from an operating compressor in excess user-defined set points
(2) Compressor air outlet temperatures in excess of 350°F/177°C
(3) Low air supply pressure, factory set at 100 psi (7 bar)
If the analyzer readings fall outside of alarm set points, a relay sounds a piezo alarm and illuminates one of three panel LEDs (one each for CO, temperature and pressure). This same relay (10A @ 230VAC/30VDC ampacity) can activate an external relay to automatically shut down compressors, sound an external alarm or activate emergency backup systems.
The system includes an external temperature sensor with 12-feet of cabling, an externally mounted calibration gas inlet and exhaust port. Two power options available.
