Measuring conditions in air
ducts are hardly ever ideal.
Ruggedly constructed duct
point and averaging sensors
are available in a variety of
models to meet specific
mounting requirements and
sensing applications. Averaging
ensures that temperatures are
acquired more reliably and
independent of the measuring
location and airflow conditions.
Active output signals in 0 to 10
Vdc or 4 to 20 mA and
numerous resistive signal
output versions in 10K Ohm
NTC or 1K Ohm Platinum (375
and 385) RTD ensure
compatibility.
For versions in metal housings,
standard lengths are 8’, 16’,
and 24’ for duct averaging;
4", 8", and 18" for duct point.
Analog sensors (533 and 544)
provide input for accurate loop-
powered temperature sensing
(detecting) for controllers via a
20 AWG twisted, shielded cable
pair. The loop current varies
according to the temperature
being measured.
