Description:
NTC Temperature Sensor is a detection element that feeds back the
results to the system.
It is also called thermistor or probe. Its principle is the
resistance decreases rapidly when the temperature rises.
NTC(Negative Temperature CoeffiCient)refers to thermistor
phenomenon and material with negative temperature coefficient, and
the resistance decreases exponentially when the temperature rises.
NTC Temperature sensors are widely used in household, automotive,
industrial, medical and other industries.Generally speaking,
temperature sensors are used in most electrical and electronic
products that require temperature feedback.
