HDR200 Dew Point/Temperature or Humidity/Temperature with RS-232 Output, Any Mounting Configuration

A configurable dew point or relative humidity transmitter that is perfect for applications in compressed air, dryers, and environmental chambers|Measures dew point over a wide temperature range Measures humidity from 0 to 95% RH (non-condensing) Flexible scaling range for all measurements Calibration can be performed down to -60?C Features a 4 to 20 mA or RS-232 output for easy communications|The HDR200 series is a family of humidity probes and electronic modules that offer % RH and dew point measurements with NIST traceable calibration. The all-stainless-steel probe construction coupled with a high temperature cable allows up to 200?C operations. For pressure applications, the probe is capable of handling 750 psi. It comes in 2 versions, dew point (HD200) and % RH (HR200). The HD200 pressure version features an enhanced calibration for measuring dew points down to -60?C. The HR200 relative humidity version has an accuracy of ?1.0% at 25?C. The probe and electronics provide a single two wire loop powered by a 4 to 20 mA interface. The units accept a voltage source from 12 to 28 VDC (24 VDC is recommended). These units will display temperature along with RH or dew point depending on the version selected. The RS-232 allows a user to scale their output ranges as well as displayed units. The unit and sensor are connected via a 1-meter high-temperature cable.
