The DEWTRAN-LC (patent pending) is our lowest cost series of  precision dew point chilled mirror transmitters that provide a quick and accurate measurement of dew point. The transmitter is available with two mounting styles, wall mount and duct mount. Each unit offers stable, accurate and repeatable measurements that are traceable to NIST. Dew points are measured down to -15°C @ 25°C (77F°) heat sink temperature.

The basic Dewtran LC includes one 4-20mA output which transmits the dew point temperature.   It is also available with temperature or barometric pressure output.  Those options add a second 4-20mA output signal.  The models with temperature output can also be programmed to transmit humidity as a one of the 4-20mA outputs. The humidity output would use one of the two 4-20mA outputs. 

RS232 Communications

The Dewtran LC can be programmed through an RS232 connection.  Any of the measurements can also be read via the RS232 connection.

Applications are HVAC, clean rooms, industrial processes, and the pharmaceutical industry.
