The Salwico ST200 gas detector for combustible gases is assembled in a chrome-plated ABS housing.
The transmitter is based on the so-called “one man calibration” principle, which means that the calibration takes place at the detector head only.
The sensor is a replaceable catalytic oxidation sensor and consists of detection and reference elements that are provided in a wheatstone bridge. When exposed to gas, the bridge will be unbalanced and an electric signal proportional to the gas-concentration will be converted to a 4-20mA output signal.
Sensors for other explosive gases are available upon request.
