The HN-E8 series is an intrinsically safe explosion proof structure temperature/humidity that has passed the certification test of the Technology Association of Industrial Safety. The detection section uses a polymeric capacitance humidity sensor development in-house. This device is composed of the temperature/humidity main unit, which is installed in hazardous locations, and an insulation barrier, which is configuration in non-hazardous locations to maintain safety, and outputs analog signals of DC 4 to 20 mA for temperature and relative humidity. In addition, the temperature/humidity main unit has an LCD display, so the measured values can be checked even in hazardous locations.
