CERAMIC PTC THERMISTORS:TEMPERATURE SENSORS

SENSORS

PS Series PTC Thermistors
SR Series PTC Temp Sensors

PTC thermistors are used as temperature sensors when the positive linear
portion of the R-T curve is processed with a specific range corresponding
to the desired sensing range.

The same sensing range can also be used to compensate the effect of
temperature change on electrical properties of the transistors.

L1=6.0mm	T=2.0mm
L2=7.5mm	1=3.7mm
L3=3.5mm	2=7.7mm
T=3.0mm

PTC thermistors are used to detect overheating conditions in motor windings and other heat sensitive devices. A relay
switch can be used in conjunction with the thermistor to deactivate the device at detection of overheat conditions. The
PTC thermistors can be made to have trigger function within

C of the rated temperature for the motor and a broad
protection temperature is available upon request.
