Descriptions and Applications
STE-1400 Series 10,000 ohm, Type III thermistor,
temperaturesensorsareavailableindierenthous-
ings for surface, duct, duct averaging, immersion,
strap-on, and outside air applications. All probes
are constructed to provide good heat transfer and
fast response. The averaging sensors are available in
both plenum-rated cable or with a copper probe.
Each STE-1401/1402/1404/1405 duct sensor is en-
capsulated in a 1/4-inch OD stainless-steel probe.
Theprobeprotrudesfromtheboomofthesensor
housing (if included). The probe can be inserted di-
rectly into the duct for single-point monitoring, and
mounting holes are provided to rigidly support the
assembly.
An STE-1411/1412/1413/1414/1415/1416/1417 aver-
aging duct sensor incorporates numerous sensors
inside a copper tube and is available in a 5/16-inch
ODbendablecopperprobeorinaexibleplenum-
rated cable. The completed assembly acts as a single
sensor and any temperature change is averaged
acrossthesensor.Theprobescanbebenttotany
size duct.
An STE-1421/1422 immersion sensor is encapsu-
lated in a 1/4-inch OD 304 stainless-steel probe. The
probeprotrudesfromtheboomofthesensorhous-
ing, minimizing lead length error. The probe has a
1/2-inchNPTingtobescrewedintoanHMO-
4534/4544 stainless-steel well.
The STE-1455 strap-on sensor is encapsulated in a
two-inch-long, 1/4-inch OD stainless-steel probe. The
probehasave-footleadwire.TheSTE-1454 strap-
on sensor also comes with an enclosure.
The STE-1451 outside air sensor is mounted in a
weatherproof gasketed enclosure with a sun shield
for protection against the outdoor elements. It comes
withanLBc/w1/2"NPTingforconnectionto
conduit.
The STE-1430 room sensor, designed for tamper-
resistant temperature measurement of occupied
spaces, can be mounted on an interior hollow wall in
astandardsingle-gangelectricalbox.Thesensoris
mountedbehindaatbrushedstainless-steelplate.
