Ex toxic gas detector

Universal Gas Detector Heads "uniTOX IV" are designed for use in stationary systems for the measurement or detection of high (explosive) concentrations of gases and vapours of liquids , in hazardous areas of type 1 or 2. They are designed for the detection of various gases and toxic vapours of groups IIA, IIB and IIC, with temperature classes T1...T6 - e.g.: ammonia, hydrogen sulphide, chlorine, carbon monoxide, carbon dioxide, nitrogen oxide and dioxide, sulphur dioxide, ethylene oxide, hydrogen chloride, hydrogen cyanide, ozone, freons. For use with a wide range of control panels and controllers. 12V DC power supply.

Depending on the version, they may have different types of outputs:

• current : continuous (4...20mA), or dual threshold 4/8/12mA

• OC voltage type (NC or NO), two outputs signalling exceeding alarm thresholds Al1 and Al2.

• digital - RS485 connection, Modbus RTU protocol, addressable detector.

Sensors used : semiconductor (non-selective, two-threshold detection), infrared (non-selective, detection or measurement), electrochemical (selective, detection or measurement).
Metal enclosure (aluminium), steel cable gland.
