Made for ambient air temperature measurement, this wall-mount RTD probe senses -40 to 85°C (-40 to 185°F). It provides a 4-20 mA transmitter output from a 100 Ω platinum element held to Class A tolerance per IEC 60751, with a 4-wire screw-terminal connection. A 6 mm sensing element and M12 cable gland suit it to HVAC, cleanroom, and building air monitoring.

The EWSA air temperature sensors are designed for wall or pipe mounting in harsh indoor or outdoor environments.
A rugged 1/4 in (6 mm) diameter sheathed RTD probe is housed in the center of a 1/2 in (12.7 mm) dia. outer protection tube. The RTD sensor terminal block or optional transmitter are housed in a tough aluminum alloy enclosure, rated to IP65.
