Thermistors for Temperature Measurement, Compensation, and Control
Negative Temperature Coefficient NTC Thermistors are semi-conductor non-linear resistors, which alter their resistance characteristics with temperature and the resistance of the NTC thermistor will decrease as the temperature increases.
Ametherm’s NTC thermistors are manufactured from a specially-formulated high quality metal oxide ceramic material which is extremely accurate in sensing temperature used in Temperature Measurement, Compensation, and Control applications.
Application Overview Ametherm’s DG series glass-encapsulated thermistors provide long-term stability and reliability for high-accuracy temperature sensing in automotive and industrial applications. Hermetically sealed, the thermistors eliminate errors in resistance readings due to moisture penetration, while offering high operating temperatures and a compact size. DG Series Application Benefits • Provide faster, more-accurate, and less-expensive alternatives to thermocouples and RTD probes • Free from limitations due to solder temperature, which enables them … Continue Reading
The Relationship between Thermal Time Constant and Temperature Sensors In this article, we’ll break down the relationship between the thermal time constant and NTC thermistors. We’ll also cover the importance of selecting the right thermistor with characteristics that will produce the correct thermal time constant for your application. Further down in this article, we demonstrate one way to measure thermal time constant; running two tests, then present the results. What is Thermal … Continue Reading
Temperature Sensors – Thermistors vs Thermocouples We Weigh the Pros and Cons of Each Type of Temperature Sensor Thermistors vs Thermocouples. They’re both good choices for temperature measurement and temperature control applications depending on your application requirements. For electrical engineers faced with the task of managing one or more temperature detection circuits, choosing the right temperature sensing device for a Printed Circuit Board (PCB) can be confusing. When you go … Continue Reading
