WZPK2-338 platinum rtd Hereaus Thin Film Pt100 surface sensor is smaller in diameter and easier to bend than assembled platinum resistance, which is suitable for special occasions such as narrow pipeline, rapid response and miniaturization. It can automatically detect the gas, liquid medium and solid surface in the temperature range of - 200 ~ 500 ℃, and can be directly connected with the secondary instrument by copper wire. Because of its good electrical output characteristics, it can provide accurate input values for display instrument, recorder, regulator, scanner, data recorder and computer. The outer protective tube of armored thermal resistance is made of stainless steel, which is filled with high density oxide insulator. Therefore, it has strong anti pollution and excellent mechanical strength, and is suitable for installation in bad environment. Armored platinum resistance is usually composed of armored platinum thermistor temperature sensing element, installation and fixing device, wiring device and other major components.
Armored thermal resistance measures the temperature of a substance as its resistance changes with temperature. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value.
