The sensor is ATEX approved to II 1G EEx ia IIC T4 (Ta = -40°C to +80°C). This designates the sensor as belonging to; Group II: suitable for all areas except mining, Category 1 G: can be used in areas with continuous, long or frequent periods of exposure to hazardous gas (Zone 0). Protection class ia, denotes intrinsically safe for all zones. Apparatus group IIC: suitable for IIA to IIC explosive gas. Temperature class T4: maximum sensor surface temperature under fault conditions 135°C. Ambient temperature range extended to -40°C to 80°C.

Intrinsically safe sensors must be used with a galvanically isolated barrier with safety parameters not exceeding:- Ui: 11.4V, Ii: 0.46A, Pi: 0.51W. Sensor can be installed with a cable length up to 150m maximum from the barrier, capacitance and inductance can be up to:- Capacitance: 550 nF max, Inductance: 99 µH max.

Approved barriers are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs. The sensor is calibrated to suit the selected barrier transmission output.
