Intrinsically Safe Humidity and Temperature Sensor E+E Elektronik EE100Ex

SKU: EE100Ex-T1
(1 customer review)

Intrinsically Safe Humidity and Temperature Sensor E+E Elektronik EE100Ex is certified ATEX Zone 1 use for hazardous areas. Backed up with IECEx approval. The EE100Ex intrinsically safe sensor measures reliably relative humidity (RH) and temperature (T) in explosion hazard areas. Powered by any intrinsically safe power source or via Zener barriers. It also calculates the dew point (Td) and frost point (Tf) temperature. It features very robust sensing head and IP65.

The Intrinsically Safe Humidity and Temperature Sensor E+E Elektronik EE100Ex is certified ATEX Zone 1 use for hazardous areas. Backed up with IECEx approval. The EE100Ex intrinsically safe sensor measures reliably relative humidity (RH) and temperature (T) in explosion hazard areas.

Measurement Performance: Beside of the very robust sensing head, the proprietary sensor protection and encapsulated measurement electronics inside the probe, the EE100Ex stands for best accuracy and long term stability over the working range 0…100 % RH and -40…60 °C (-40…140 °F).

Reliable in Harsh Environment: It means that the entire device can be placed in explosion hazardous area. Due to the rugged metal IP65 enclosure and the choice of filter caps, the EE100Ex performs reliably in a wide range of demanding applications such as utility tunnels, hazardous storage rooms or pharmaceutical industries.

Power Supply and Outputs: The device can be powered by any intrinsically safe power source or via Zener barriers. Beside RH and T, the EE100Ex calculates the dew point (Td) and frost point (Tf) temperature. The measured data is available on two galvanic isolated 4…20 mA, 2-wire outputs.

Protective Sensor Coating

  • The E+E proprietary sensor coating is a permeable layer applied to the active surface of the RH sensing element. The coating extends substantially the life-time and the measurement performance of the E+E sensor in corrosive environment. Additionally, it improves the long term stability in dusty and dirty applications by preventing stray impedance caused by deposits on the active sensor surface.

Typical Applications

  • Explosive, hazardous storage rooms
  • Utility tunnels
  • Pharmaceutical industry
