working principle

Wz seriesKaizhuang thermistorThe principle of temperature measurement is based on conductors or semiconductors

The characteristic that the resistance value changes with temperature is used to measure temperature and temperature related parameters. Most thermistors are made of pure metal materials, with platinum and copper being the most commonly used. Currently, materials such as nickel, manganese, and rhodium have been used to manufacture thermistors. Thermistors typically require the transmission of resistance signals through leads to computer control devices or other secondary instruments.

Main types

Ordinary type thermistor

According to the temperature measurement principle of thermal resistance, the change in the measured temperature is directly measured through the change in the resistance value of the thermal resistance. Therefore, the change in resistance of various wires such as the lead wires of the thermal resistance body will have an impact on temperature measurement.

Armored Thermistor

Armored thermistor is a solid body composed of temperature sensing elements (resistors), leads, insulation materials, and stainless steel sleeves. Its outer diameter is generally between 2 and 8mm, and can be as small as 8mm. Compared with ordinary thermistors, it has the following advantages:

1. Small size, no air gap inside, low measurement lag in terms of thermal inertia;

2. Good mechanical performance, vibration resistance, and impact resistance;

3. Can bend, easy to install;

4. Long service life.

Explosion proof thermistor

Explosion proof thermistor uses a special structure of junction box to confine the explosion of explosive mixed gas inside its shell caused by sparks or arcs within the junction box, so as not to cause excessive explosion in the production site. Explosion proof thermal resistors can be used for temperature measurement in areas with explosive hazards within Bla-B3c class zones.
