KHD2-T85 Duct Mounted 2% Temperature Humidity Sensor, 1000Ω RTD @32˚F (0˚C).
The Kele KHR, KHD, and KHO Series humiditytransmitters are specifically designed for use in HVAC/BASapplications. These instruments measure relative humidityfrom 0% to 100%. The standard two-wire, 4-20 mA outputprovides low-cost humidity monitoring for building control.The RH transmitters are available with thermistor or RTDtemperature sensors. They come in room (KHR), duct (KHD),and OSA (KHO) mounting styles.
OPERATIONThe transmitter converts the relative humidity into a4-20 mA signal with the latest microprocessor capacitivedesign. Multipoint factory-automated calibration improvesaccuracy and repeatability. The optional temperaturesensors, thermistor or RTD, offer direct connections to mostautomation systems.
