Analytical Instrumentation & Environmental Monitoring


Wall mount temperature and RH transmitter

February 2012 Analytical Instrumentation & Environmental Monitoring

Michell Instruments has introduced the WM33 and 52 wall mounted units that provide a % RH, dew point or absolute humidity and temperature output signal of excellent accuracy and stability. WM33 is designed for low cost HVAC applications and the WM52, incorporating digital technology, is ideal for accurate measurements in controlled environments. Both sensors are easy to calibrate for high accuracy in measuring ranges of 0–100% RH and -20 to 80°C.

Output signals are 4–20 mA, 0–1, 0–5, and 0–10 V, with supply voltages of 5–30 VDC. The electronics is housed in a white moulded polymer enclosure with connections made via screw terminals.
