It measures temperature, relative humidity and derived dew point on the same channel, so a single duct insertion covers the three variables an AHU or clean-room panel typically logs. ## 82 mm probe, 101 mm body — what fits the duct With an 82 mm probe diameter and 43 mm installation depth, the SH3XD22 seats into a standard duct tap without protruding into the airflow far enough to disturb the reading — the 182 mm overall height and 101 mm body width clear most terminal-box lids once the probe is committed. Internal mounting and IP65 around the housing keep the electronics side of the partition clean while the sensing tip reads the airstream; the gasket at the duct face is the wet-side barrier, so torque it down on a flat gland surface to keep the IP65 rating honest. ## 0-40 °C, 0-100 %RH — coverage that matches HVAC duty The 0...40 °C temperature range and 0...100 % humidity span line up with conditioned-air and process-room envelopes rather than outdoor or freezer duty — this is an indoor-air probe, not a chiller or rooftop sensor. A 4...20 mA loop on two wires lets the cable run share conduit with other low-voltage instrumentation, and scaling both ranges into the same 4-20 mA channel means the downstream PLC or BMS card reads either variable from one analogue input.","metaTitle":"SH3XD22 Duct Temp/Humidity Sensor, 4-20 mA, IP65","metaDescription":"SH3XD22 active-production duct temperature and humidity sensor, 4...20 mA 2-wire loop, IP65, 0...40 °C.
