Excellent Moisture Resistance NTC Temperature Sensor Use For
Household Appliances
NTC thermistors can be assembled into customized NTC temperature
sensors in various product applications for measurement, detection,
indication, monitoring and control. NTC temperature sensor probe
assemblies can be easily connected to any system or an integral
part of any system to monitor or control temperature, the choice of
assembly depends on the application. The main factors that
determine the best form factor configuration of an NTC temperature
sensor assembly are the operating environment, installation, time
response, and minimum dissipation constant.

►Different NTC thermistor using in the NTC temperature sensors with
the following different operating temperature:
Chip or MF52A,MF51E,MF55: temperature resist grade 125℃,actual
temperature resist grade 150℃
MF58: temperature resist grade 200℃,actual temperature resist grade
250℃
MF51: temperature resist grade 200℃,actual temperature resist grade
250℃
Special MF51: temperature resist grade 250℃,actual temperature
resist grade 300℃
Weldless chip:temperature resist grade 450℃,actual temperature
resist grade 500℃
►Operating environment
In the environment of high temperature,high humidty and high
corrosion,we suggest to use glass sealed type thermistor as the
core element.And MF51 type will be the best NTC thermistor in high
humidity environment.
►Design considerations and procedure of temperature sensor:
1. Choose the shape acoording to customer's design or assemble
requirements, and confirm the thermistor.
2. Confirm the thermistor element and other materials according to
customers' requirement
3. Choose the suitable resistance,B value and tolerance
4. Choose suitable moisture-proof and insulation technology to meet
customer's requirement
5. Choose suitable encapsulation structure to meet performance
requirements of mechanical shock resistance
6. Meet customer's special requirements.
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.
