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