Gas detector calibration in remote locations

23 April 2009

Calibrating the Model S4000CH Combustible Gas Detector with a remotely-installed sensor is now easier than ever with the Automatic Remote Gas Calibrator (ARGC) from General Monitors.
The ARGC consists of a Remote Gas Calibrator (RGC) and a solenoid valve. The ARGC blocks ambient air and re-directs the calibration gas to the catalytic bead sensor for calibration or testing sensor accuracy.

The instrument can calibrate gases at wind velocities as high as 50 mph and maximum temperatures of 75°C. After connecting the ARGC to any S4000CH Detector, the calibrator can be operated manually or electronically via HART or Modbus, or the magnet menu.

The calibrator is easy to install and use, requiring no electrical wiring or connectors. For fully automatic operation from a control room, the two bidirectional protocols (HART and Modbus) are utilised.

The S4000CH is a hydrocarbon gas detector suitable for use in SIL 3 applications and approved by FM, CSA, ATEX, GOST and has CE Marking. The ARGC and the S4000CH allow operators to calibrate sensors from the ground or in the convenience of a control room, reducing maintenance costs.
