Working Principle of RTD & How do they Work?

What is an RTD?
RTD stands for resistance temperature detector. It is also know as a resistance thermometer. It is a type of temperature sensor which provide high accuracy and stability.

How does it work?
Resistance Temperature Detectors, also known as RTDs and resistance thermometers, it can change resistance at a predetermined rate in response to changes in temperature. They are circuit elements whose resistance increases with increasing temperature in a predictable manner.

ZHYQ’ RTDs are specially designed to ensure precise and repeatable temperature versus resistance characteristics. The sensors are constructed in a unique strain-free manner and use only high-quality RTD elements.

We have types of K(800-1200℃),E(600-800℃),T(350-400℃),J(600-700℃),PT100(0-600℃),CU50(-50~100℃) for per customer’s requirements to ensure the most suitable specification is supplied.
