The Siemens controller module * * 6ES7590-1AB60-0AA0 $r $n sensor is more suitable. The more widely used thermal resistance materials are platinum, copper, nickel, etc. They have the characteristics of high temperature coefficient of resistance, good linearity, stable performance, wide temperature range of use, and easy processing. Classification of temperature resistance sensors used for measuring temperatures within the range of -200 ℃ to+500 ℃: NTC thermistor sensors are negative temperature coefficient sensors, meaning that the sensor resistance decreases with increasing temperature. PTC thermistor sensors are positive temperature coefficient sensors, meaning that they are sensors
