RMCalibar -- Remote Calibration Panel
Sensors are seldom sited for easy access. Methane and natural gas sensors are normally installed in the roof peaks and skylight areas, because methane is lighter than air. Propane sensors are placed low near the floor and in service pits because this gas is heavier than air. Remote calibration permits each sensor to be calibrated and adjusted without risking accidents with lifts and ladders. There is, of course, no need to stop production and move vehicles out of the way to access sensors directly. On initial installation, gas supply tubing is installed for delivering calibration gas to each sensor from a convenient floor level station. The two 4-channel Rem-Cal circuit boards in the DXcalibar or RMcalibarTM boxes permit each of eight sensor signals (4-20ma) to be finely adjusted. Test jacks are included on these Rem-Cal modules for local read out of the raw signal from each sensor as well as the calibrated signal, using a hand held milli-ammeter.
