Wide-range Linear Analysis and Procedures of NTC Thermistors

Hao Cheng

Abstract

Due to its low price,NTC thermistor is often used in industry to replace the thermocouple or integrated temperature sensor for temperature measurement,which will reduce the product cost in mass production.However,due to its great non-linear temperature resistance,in a wide temperature range of measurements,data acquisition and processing the microprocessor system may lead to significant errors.Based on the data analysis of HCS34B502F-E5015 thermistor type temperature sensor,this paper reaches a VF conversion of temperature measurement considering its low-cost microcontroller-based system.
