Overview
The Tiankang PT100 thermal resistance temperature measurement is based on the characteristic that the resistance value of metal conductors increases with temperature. Most thermistors are made of pure metal materials, with platinum and copper being the most commonly used. In addition, materials such as nickel, manganese, and rhodium have been used to manufacture thermistors.
Product Details
During the installation of the Tiankang PT100 thermistor, as its leads are connected to the resistance element, it is necessary to rotate the leads synchronously with the end face thermistor to ensure that they are not artificially damaged during installation. However, this situation is inevitable during the actual installation process. Due to the occurrence of this situation, Anhui Instrument has increased its research efforts and successfully developed a special device that only requires tightening the screws on the outer end during installation, without the need for lead wires and synchronous rotation.

Types of Thermal Resistors
1) Ordinary type thermistor
According to the temperature measurement principle of thermal resistance, the change in the measured temperature is directly measured by 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.
2) 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 2mm. 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, and has a long service life.
3) The temperature sensing element is wound with specially treated resistance wire material.
4) 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.
