Autonics THD-W1-C Temperature Humidity Transducer

Autonics THD-W1-C Temperature Humidity Transducer is a wall-mounted environmental sensor with a 100 mm sensing pole and dual DC 4–20 mA outputs for simultaneous temperature and humidity measurement when powered from 24 V DC. It measures temperature from -19.9 to 60.0 °C and relative humidity from 0.0 to 99.9% RH, with a 500 ms sampling interval and an IP65-rated housing (sensing portion excluded) to withstand demanding environments. Temperature accuracy is ±1.0 °C at room temperature, while humidity accuracy is ±2% RH over 10–90% RH at room temperature, with a maximum stated humidity error up to about ±2.5% RH under certain conditions. The unit’s enclosure is 72 × 185 × 34.5 mm, it uses a 100 mm sensing pole, and it weighs about 415 g gross (net approximately 160 g). This makes it suitable for wall-mounted HVAC monitoring, data-center environmental control, laboratories, and industrial processes where reliable, loop-powered temperature and humidity signals feed into remote readouts or control systems.
