Fast Response High Precision 60K 70K 100K NTC Temperature Sensor
For Refrigerator
Thermistor probes are invaluable for sensing temperature levels in
a variety of industries ranging from HVAC and food handling to
automotive and laboratory research. In such applications, it's
critical that the thermistor probe used is accurate to ensure
reliable thermal monitoring.
A world-class provider of thermistors and thermistor probes and
assemblies, We offers temperature probes designed and built from
the ground up. The thermistors we use are created from a precise
blend of raw materials and processed using proprietary techniques
that result in superior discrete components, probes and assemblies.

The main technical parameters:
1. The rated zero-power resistance value R25 refers to the
zero-power resistance value of the thermistor measured at 25°C.
2. B value; defined as the ratio of the difference of the natural
logarithm of the zero-power resistance value at two temperatures to
the difference between the two temperatures.
3. Thermal time constant; under zero power conditions, when the
temperature changes suddenly, the time required for the temperature
of the thermistor body to change by 63.2% of the temperature
difference between the beginning and the end.
4. Dissipation coefficient; at a specified ambient temperature, the
ratio of the change in power dissipation of the thermistor to its
corresponding temperature change.
Application

Working principle of temperature sensor
Using the NTC thermistor under a certain measurement power, the
resistance value drops rapidly as the temperature rises. Utilizing
this feature, the NTC thermistor can be used to determine the
corresponding temperature by measuring its resistance value, so as
to achieve the purpose of detecting and controlling the
temperature.
