EE211

The EE211 is dedicated for accurate and long term stable measurement under continuous high humidity (>85 %RH) and condensing conditions in demanding climate control. It features a heated humidity (RH), and an interchangeable temperature (T) probe.

Humidity and Temperature Sensor for Continuous High Humidity

  • Humidity
  • Temperature

It features a heated humidity probe and an interchangeable temperature probe. Excellent performance of EE211 even in polluted, aggressive environment is ensured by the combination of completely encapsulated measurement electronics inside the humidity probe and the long-term stable HCT01 sensor with E+E proprietary Sensor coating.

The EE211 enclosure is rated IP65/NEMA 4, minimizes installation costs and provides outstanding protection against pollution and condensation. All measured and calculated values are available on the Modbus RTU interface whereas two of the values are available on the analogue voltage or current (3-wire) output. Additionally up to three values can be shown simultaneously on the optional illuminated display.

With the optional USB configuration adapter the user can set the Modbus RTU interface parameters, the display format, the measured parameters and the output scaling. Furthermore, the user can perform an one or two point humidity and temperature adjustment. The T probe can also be adjusted separate, whereby the reference can be a high accuracy dry block calibrator.

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.
