NTC Thermistor Experiment 

By measuring the temperature characteristics of the thermistor, combining with the bridge circuit, and based on theoretical analysis and design, the instrument experimented with the design of a linear display digital thermometer, which has high sensitivity and a temperature range suitable for measuring the body temperature of the human body.

Introduction

1. Measure the characteristics of NTC thermistor;
2. Design a digital thermometer with a linear display of 30～50℃.
The main technical parameters:
1. DC 0～2V precision adjustable power supply, maximum current 10mA, stability: 0.02%/min;
2. NTC thermistor, with metal package or separate components;
3. With electric heater and water container;
4. Portable digital thermometer, -40～150℃, resolution 0.1℃, accuracy: ±1℃;
5. One digital multimeter with 4 and a half digits display;
6. One adjustable resistor board, including 3 adjustable resistors.
*Different technical requirements can be customized.
