What is armored thermistor and how to judge its quality? 1

Armored thermistor is a BH7673G-TR sensor used to measure temperature, widely used in various occasions where temperature measurement and control are required. It usually consists of an internal resistance element and an external metal protective sleeve (armor). The internal resistance components are usually made of metals such as platinum, copper, or nickel, whosediode resistance values vary with temperature. When the temperature rises, the resistance value of the metal increases, and vice versa, it decreases. By measuring the resistance value of the component, the corresponding temperature value can be calculated.

The characteristics of armored thermal resistance are good stability, accuracy, and fast response. At the same time, due to the protection of the external metal protective sleeve, it also has good mechanical strength and anti-interference ability.diode

According to the material and structure of the temperature sensing element, armored thermistors can be divided into several different types, including platinum resistors (Pt100, Pt1000), copper resistors (Cu50, Cu100), etc. Among them, Pt100 means a platinum resistor with a resistance value of 100 ohms at 0 ° C.diode
