Galltec+Mela Humidity and Temperature sensors with ATEX certification
The Galltec+Mela Humidity and Temperature sensors with ATEX certification are suitable for use in potentially explosive atmospheres and areas with combustible dust equipment of category 1G, 1/2G and 2D. The sensors consist of a sensor part with a sintered filter (both made of stainless steel) on a robust die-cast aluminium housing (transmitter part). MELA-humidity/-temperature sensors in this series are used to measure relative humidity and temperature in air, and other non-aggressive gases in explosion hazardous areas and locations with inflammable dust.
Connection to a non-intrinsically safe electric circuit for humidity (F*C3.Ex/8) and for temperature sensors (T*C3.Ex/8) is achieved with a 1-channel transmitter power supply unit, and for the combined humidity and temperature sensors (K*C3.Ex/8) either with a 2-channel or with two 1-channel transmitter power supply units with galvanic isolation between input-/output circuits and power supply.
These IP65 rating humidity/temperature sensors provide two analog outputs of 4–20 mA with the accuracy for humidity ± 2 %RH 5...95 %RH at 10 ...40 °C and temperature ± 0.2K at 23°C. The humidity/temperature sensor is mounted on the wall of the hazardous area with class 1 requirements by using assembly kit ZA 40.
Possible applications for these types of sensors include industries like chemical, drying, pharmaceutical, paper & print, environmental, mining and paint shops, etc.
