■Test Circuit Diagram and Resistance vs. Temperature
■Application Notes
● Operate the sensor under the specifi ed maximum
per mis si ble electric power. Otherwise, it gen er ates
heat, which may cause malfunction and de te ri o ra tion
of its characteristics.
● Resistance values of the sensor shall be measured
by the specifi ed measuring circuit, described in the
individual specifi cation.
● Do not operate the sensor above the Operating
Tem per a ture Range.
● When attaching the sensor with a screw, do not touch
the terminal area. Do not apply excessive torque and
pres sure when screwing, otherwise the product may
become damaged and malfunction.
● The sensor may be damaged or deteriorated when
dropped or exposed to a large impact. Excessive
shock and impact shall not be applied.
