OPERATION
PTC thermistors exhibit very high sensitivity over a
narrow temperature band. For temperature measure-
ment in this range, NTC thermistors are easier to
measure and more accurate.
PTC thermistors are especially suited as temperature
sensors for monitoring the windings of electric
machines, and also for use in simple fail-safe circuitry.
When a given temperature (nominal response tempe-
rature
off through a relay or amplifier, since the PTC-sensor
will have an extremely high ohmic value in the region
of its response temperature. This will have the same
effect as a break in the circuit or a failure of the
thermistor.

SPECIAL VERSIONS
PTC’s are also available in many special housings
(can be manufactured to customers specifications)
INSTALLATION TIPS
For PTC temperature sensors in electrical windings:
- the thermistors can only be inserted in the windings
- it is advisable to embed one in each phase, if
- air inflow onto the temperature sensor will interfere
- if using varnish/lacquer which is not chemically
- WARNING! It is very important that the sensor must

be installed parallel with the copper of the winding,
so that the teflon leads can assume the form of the
rest of the winding and thereby retain the high-
voltage resistance rating.
