Wall-mounted temperature/humidity (intrinsically safe explosion proof ) HN-E8 (Japan Stadnards)

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.

For measuring temperature/humidity in explosion proof environments Wall-mounted temperature/humidity (intrinsically safe explosion proof structure)

  • Equipped with a small sensor unit that enables high accuracy measurement (sensor unit diameter is φ12mm)
  • The sensor part is a plug-in compatible type.
  • specifications includes sensor unit integrated and separate types to suit the usage environment. Separate cable lengths are available in three types: 1m, 2m, and 3m.
  • The sensor part is a fully interchangeable type, so only the sensor part can be replaced, making maintenance easy.
  • Because it uses an insulation barrier system, there is no need for the "stand alone Class A installation work" that was required with the conventional Zener barrier system.
  • temperature/humidity and hygrometer has an LCD display, so you can check the measured values even in dangerous areas.

Application Examples

  • Hazardous materials storage facility
  • Pharmaceutical companies
  • Film Production Line
  • Vehicle Paint Booth
