Temperature Sensors
Overview
CPC supplies a variety of temperature sensors for use in
a number of different applications. Most temperature sen-
sors are alike in their basic functions: they are polarity-in-
sensitive 10k
Ω
thermistors that provide accurate
temperature readings within a range of -40° F to 150° F (-
40° C to 65° C).
Table 12 gives a list of all temperature sensors offered
by CPC.
Mounting and Location
Inside Temp Sensor
The inside temperature sensor is supplied within a wall-
mounted enclosure that is attached to a standard switch
plate.
The temperature sensor should be located in a central
location—within the zone to be measured—away from
doors, windows, vents, heaters, and outside walls that
could affect temperature readings. The sensor should be be-
tween four and six feet from the floor.
Mount the sensor using the screws provided as shown
in Figure 28.
