Summary: This paper introduces a method for accurately measuring the resistance of three-wire thermal resistance by constant voltage partial pressure method. For Pt100 thermal resistance, the detection resolution can reach 0.005W. At the sam....
Three conventional applications for thermistors: surge absorption, temperature measurement, and temperature compensation. NTC Thermistor It is a negative temperature coefficient thermistor. The resistance decreases with the increase of tempe....
In the field of NTC thermistors, there are currently two insufficient NTC thermistors and single-ended glass-sealed thermistors on the market. Among them, single-ended glass-sealed NTC thermistors are mostly insulated through insulated bushi....
What is the significance of linearity? Linearity is the degree of linearity that describes the output voltage of the sensor varies with temperature . In fact, it is the maximum deviation of the sensor output voltage from the ideal fit line....

The temperature of the chip is one of the most important parameters in the operation of power electronics. One possible way to measure the temperature of the chip is to measure the temperature of the substrate as the base data and then calcu....
Proper selection of NTC thermistor/temperature sensors requires consideration of the following: I. Learn about product application features: 1. Temperature measurement 2. Temperature compensation 3. Inrush current suppression II. Classified....
The electric heating system has gone through the long process of ordinary heating wire, alloy heating wire, electric heating film, PTC heating element , and the alumina ceramic heating core (MCH) widely used today. The so-called MCH alumina....
At the moment when the power circuit is energized, the energy of the external power source is first transferred to the input filter capacitor. This instant generates a large surge current, if not limited, it is easy to damage the fuse and su....
This article provides a more conventional method of collecting temperature using an NTC thermistor. First, an NTC thermistor having a resistance value of Rn=10K and a thermal index of B=3950 is used when the rated temperature Tn=25C. The met....
