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 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.
