OMEGA’s rugged air temperature sensors EWSA series offer the perfect solution for temperature monitoring outdoors or in demanding environments. A 6 mm–diameter sheathed RTD (Pt100, Pt1000) probe is housed in the centre of a 12.7 mm outer protection tube which is drilled to improve airflow around the sensor.

A 4-terminal connector block or 4 to 20 mA transmitter are housed in a tough aluminium alloy enclosure rated to IP65. A cable gland is fitted on the opposite side of the enclosure to the sensor, suitable for cables from 2.5 to 6.5 mm diameter.
