RH/Temp Transducer Dual Setpoint Adjust SP Series

The SP series RH/T transmitter incorporates two sensors in one attractive wall mount enclosure for the most efficient environmental monitoring and control system. It uses a field-proven RH sensor to monitor relative humidity over 0-100 %RH and a curve-matched thermistor to measure temperature over common field-selectable ranges. Two setpoint controls are also available for temperature and RH adjustment. The device may also include an occupancy override button and an external communication jack. Both measurements and setpoint signals are continuously available on separate outputs as linear 4-20 mA, 0-5 or 0-10 Vdc signals. Several configurations of the device are available with one to four outputs as required. An LCD is included for configuration and local indication of all parameters. Several operating parameters can be programmed using a keypad for specific applications including four temperature ranges and C/F display.
