Humidity Detector in a compact design / Modbus RTU interface /
measures air humidity, temperature / calculates the dew point and absolute humidity
The Humidity Detector measures air humidity and air temperature. The Humidity Detector calculates the dew point and the absolute humidity from these two values. The measurement data from the Humidity Detector are output via the Modbus RTU interface. This makes the Humidity Detector suitable for mass applications where the humidity and temperature must be measured quickly and easily.
Due to the compact dimensions, the Humidity Detector can be easily installed in control cabinets, on walls or in cavities. Optional filters protect the sensor element from the Humidity Detector from external influences such as moisture or dust. A simple cable connection creates the connection between the Humidity Detector and a Modbus master. The Humidity Detector can be used in conjunction with a Modbus display, a Modbus data logger or a paperless recorder.
