This sensor combines the
usefulness of our ultra-precise air
measurement RTD sensors with
the convenience of our PR-21 M12
enabled RTD sensors. The design
of the probe includes a perforated
sheath over the sensing element
shielding it from debris while
allowing airflow to directly reach
the element. This results in
a sensor which is capable of
providing accurate, fast responding
temperature measurements.
OMEGA also offers a wide variety
of compression fittings, extension
cables and measurement and
control instruments which allow
you to fully customize the system
to best meet your measurement
and control needs.
