Humidity / Temperature Transmitters

Sensors with an electrical transmission output for remote indication of humidity. Some products have an LCD display while others have different designs. Some transmitters are mounted.

Model 657-1
Dual Channel Design for Simultaneous 4-20 mA Output Signals

Relative Humidity/Temperature Transmitter has a stainless steel probe that can easily mounted to most ductwork. Applications include clean room monitoring, HVAC, and building control.
Model 657C-1
Dual Channel Design for Simultaneous 4-20 mA Output Signals – Conduit Housing

Relative Humidity/Temperature Transmitter produces separate output signals for both relative humidity and temperature.
Series RH-R
Remote Mount, Field Replaceable Sensor Filter, Up to 16' Cable

Humidity/Temperature Transmitter is an ideal transmitter for applications where space is limited. Ideal for environmental chambers, rubber bladder burst detection, and air handler applications.
Series RHP
Passive Temperature Outputs, Sintered Filter Options

Humidity/Temperature Transmitter combine voltage or current humidity transmitter output with a passive temperature thermistor or RTD output.
Series WHT
Compact Housing, Sintered Filter

Weather-Resistant Humidity/Temperature Transmitter is designed to withstand elements. Ideal for measuring outside air temperature and humidity levels for air handling economizer applications.
Series HHT
Intrinsically Safe or Explosion-Proof Models

Hazardous Area Humidity/Temperature Transmitter takes accurate measurements in the harshest environments. Sensor should be replaced annually or sooner depending on conditions.
Series RHP-W
Optional LCD Display

Wall Mount Humidity/Temperature/Dew Point Transmitter is the most versatile room transmitter. Sensors are field replaceable to reduce service cost and inventory.
Series WHP
Transmits up to 100 Feet, Battery Operated

Wireless Humidity/Temperature Sensor provides flexibility in locating sensors and reduces wiring cost. The duct mount and outside air mount sensors come standard.
Series RHRS
6 or 10 Plate Design, Integral Pipe Mounting Kit

Outside Air Humidity Radiation Shield protects outside air humidity transmitters from rain and radiated heat. Applications include weather stations and building outside air reference.
Series RHP-E/N
Optional LCD Display

Wall Mount Humidity/Temperature/Dew Point Transmitter is the most versatile with a stylish housing that is well vented to improve measurement accuracy.
Series RHPLC
2% or 3% Humidity Sensor, Passive Temperature Outputs

A compact economical sensor for the building automation market space.
