OMEGA Engineering, Inc. Dewpoint Transmitters RHCM

The RHCM series is a family of low cost, high performance chilled mirror dewpoint transmitters. The sensor provides accurate long term repeatability and high reliability performance for process control and energy management. The RHCM-10 sensor electronics are housed in a rugged enclosure which can be wall mounted for climate control. The RHCM-20 and RHCM-30 sensors are designed to be either pipe or duct mounted for process control in HVAC/Energy management applications. Field calibration is not required and the ambient temperature effects, hysteresis, and calibration drift with age are all virtually eliminated. The RHCM series offer a wide range of user specified power inputs including 24 Vdc, 24 Vac, 115 Vac and 230 Vac, for many applications. The user specified outputs include 100 platinum RTD (4-wire) or 4 to 20 mA, which can be scaled over three different temperature ranges of 0 to 100F, 0 to 50C and -40 to 140F. Either output can be directly connected to a panel meter, controller or data acquisition system.
