    Measurement Performance
    With the very robust sensing head, the proprietary sensor protection and the encapsulated measurement electronics inside the probe, the EE100Ex stands for best accuracy and long term stability.

    Reliable in Harsh Environment 
    Due to the robust metal IP65 enclosure and the wide choice of filter caps, the EE100Ex performs reliably in demanding applications such as utility tunnels, hazardous storage rooms or pharmaceutical industry.

    Power Supply and Outputs
    Besides measurement of relative humidity and temperature, the EE100Ex calculates dew point [Tf] and frost point temperature [Td]. The intrinsically safe humidity and temperature sensor features two galvanically isolated 4-20 mA outputs in 2-wire technology.

    FAQ

    Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
