The Series RHP-W Wall Mount Humidity/Temperature/Dew Point Transmitter is the most versatile room transmitter on the market. The stylish housing is well vented to provide air flow across the sensor to improve measurement accuracy. An optional LCD display can be integral to the transmitter or a remote display can be ordered for building balancing or LEED® validation. The LCD display indicates the ambient temperature along with the humidity or dew point. The transmitter has internal dip switches to select the temperature engineering units and whether the transmitter outputs humidity or dew point.

The humidity and temperature sensors are field replaceable to reduce service cost and inventory. The humidity and the dew point are measured using a capacitive polymer sensor that completely recovers from 100% saturation. The humidity and dew point can have either a current or voltage output, while the optional temperature output can be a current, voltage, RTD or thermistor. For models with current or voltage for the temperature output, the temperature range is field selectable.

          • Loosen plastic probe retainer on radiation shield by unscrewing two retainer screws.
          • Slide humidity transmitter probe completely into radiation shield.
          • Screw plastic probe retainer to the radiation shield until the probe is firmly held in place. Do not over tighten the screws.

          For Pipe Mounting:
          • Remove the u-bolt from the mounting bracket.

          For Surface Mounting:
          • Remove the u-bolt and the screw holding the pipe retaining bracket.
          • Mark the outer two holes of the mounting bracket on the surface.
          • Drill the two holes marked in the previous step into the surface.
          • Attach the radiation shield to the surface.
