Description

OMEGA’s rugged air temperature sensors offer the perfect solution for temperature monitoring outdoors or in demanding environments.
A 6 mm–diameter sheathed RTD probe is housed in the center of a 12.7 mm (0.5") 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 aluminum alloy enclosure rated to NEMA 4X (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 (0.098 to 0.25") diameter.
