The RHCM Series is a family of high-performance chilled mirror dewpoint transmitters. The sensors are designed to provide accurate long-term repeatability and reliable performance for process control and energy management.

RHCM-10 sensor electronics are housed in a rugged enclosure that can be wall-mounted for climate control. 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 offers a range of user-specified power inputs including 24 Vdc, 24 Vac, 115 Vac, and 230 Vac. User-specified outputs include 1001/2 platinum RTD (four-wire) or 4-20 mA, which can be scaled over three different temperature ranges of 0 to 100°F, 0 to 50°C, and -40 to 140°F. Each output can be directly connected to a panel meter, controller, or data acquisition system. Price is $975.
