225-THT-1 Temperature and Relative Humidity Sensor

The 225-THT-1 Temperature & Humidity Sensor is configured for measuring relative humidity and temperature in environmental control systems, where condensation or dust will commonly be encountered. A fully gasketed watertight enclosure, locking strain relief connections, and a brass sintered filter protect the electronics and sensors from environmental or mechanical damage.

An electronic circuit in the enclosure converts the capacitance to a voltage output which is linearly proportional to the ambient relative humidity. Temperature is sensed by a 100 ohm platinum resistance element and converted to a linear analog output. The sensor should be mounted in a solar radiation shield when placed outdoors. The remote probe comes with four feet of cable and a mounting clamp.

The sensor can be powered by 10-30Vdc, 120Vac 50/60Hz, or 220Vac 50/60Hz. It features three outputs for relative humidity and three outputs for temperature, 0-1V, 0-5V, and 4-20mA. All six outputs are available on a terminal strip inside the enclosure and can be used at the same time.
