What are the car temperature sensors

source:http://www.finecomtech.com/news/xyzx/57.html   release time:2020-09-27

The temperature sensor is mainly used to detect engine temperature, intake air temperature, cooling water temperature, fuel temperature and catalytic temperature. There are three main types of temperature sensors: wire-wound resistance, thermistor and thermocouple resistance. The three types of sensors have their own characteristics, and their applications are also slightly different.

Wirewound resistance temperature sensor has high accuracy, but poor response characteristics;

The thermistor type temperature sensor has high sensitivity and good response characteristics, but the linearity is poor and the adaptation temperature is low;

The thermocouple resistance temperature sensor has high accuracy and a wide measuring temperature range, but it needs to be used with an amplifier and cold junction processing.

The practical products include thermistor temperature sensor (universal type -50℃~130℃, accuracy 1.5%, response time 10ms; high temperature type 600℃~1000℃, accuracy 5%, response time 10ms), ferrite type Temperature sensor (ON/OFF type, -40℃~120℃, accuracy 2.0%), metal or semiconductor film air temperature sensor (-40℃~150℃, accuracy 2.0%,
