A dual heating system prevents condensation on the humidity sensor, on the sensing probe and on the filter cap. This leads to an extremly short response times and fast recovery after condesing conditions.

The measuring principle with separate humidity and temperature probes enables precise and continuous measurement even at permanent high humidity.

The proprietary coating protects the sensors and their leads against corrosive and electrically conductive pollution.

Typical applications

  • Meteorology
  • Wind turbine generators
  • Road icing warning
  • Off-shore measurements

EE33-M FAQ

  • What is the difference between a 2 wire and a 3 wire current output?

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