Industry Information
Armored thermal resistance suitable for installation in harsh environments
2012-2-15 10:06:56

Armored thermal resistance is a type of temperature sensor. It has a smaller diameter than assembled thermal resistance, is easy to bend, and has good shock resistance. It is suitable for installation where assembled thermal resistance cannot be installed. The WZPK series armored thermal resistance produced by our company is introduced. Thermal resistance temperature measuring element, therefore, has the advantages of accuracy, sensitivity, fast thermal response time, stable quality and long service life.
The outer protective sheath of the armored thermal resistor is made of stainless steel and filled with high-density oxidizing material insulators. Therefore, the armored thermal resistor has strong anti-pollution performance and mechanical strength, and is suitable for installation in harsh environments. Armored thermal resistance can be used to measure the temperature in the range of -200-600 ℃. It can be directly connected to the secondary instrument with copper wires. Since the armored thermal resistance has good electrical output characteristics, it can be used for display instruments, recorders, and regulators. , Scanners, data loggers, and computers provide accurate temperature changes.
Working principle: Armored thermal resistance Working principle: Under the action of temperature, the resistance of the thermal resistance wire changes accordingly, and the display instrument will indicate the temperature value corresponding to the resistance value generated by the thermal resistance.
Main technical indicators: Resistance value of thermal resistance temperature sensing element at 100 ℃ (R100) and its resistance R0 ratio at 0 ℃: (R100 / R0)
Indexing number Pt100: Class A R0 = 100 ± 0.06Ω
Class B R0 = 100 ± 0.12Ω
R0 / R100 = 1.3850


Armored thermal resistance performance characteristics Armored thermal resistance is a type of temperature sensor, which has a smaller diameter than the assembled thermal resistance, is easy to bend, and has good shock resistance. It is suitable for installation where the assembled armored thermal resistance cannot be installed. Armored thermal resistance It has the advantages of accuracy, sensitivity, fast thermal response time, stable quality and long service life. The outer protective sheath of the armored thermal resistor is made of stainless steel and filled with high-density oxidizing material insulators. Therefore, the armored thermal resistor has strong anti-pollution performance and mechanical strength, and is suitable for installation in harsh environments. Working principle of armored thermal resistance Under the action of temperature, the resistance of the thermal resistance wire changes accordingly. The display instrument will indicate the resistance value generated by the thermal resistance. The armored re resistance is used as a temperature sensor. It has a smaller diameter than assembled platinum resistors and is easy to bend. It is suitable for installation in special occasions where the pipeline is narrow and requires fast response and miniaturization. It can automatically detect the gas, liquid medium and solid surface in the temperature range of -200 ~ 600 ℃, and can be directly connected with a copper wire and a secondary instrument for use. Because of its good electrical output characteristics, it can be used as a display instrument. , Recorders, regulators, scanners, data loggers, and computers provide accurate input values. The armored resistance outer protection tube is made of stainless steel, and it is filled with high-density oxidizing material insulators, so it has strong anti-pollution and excellent mechanical strength, and is suitable for installation in harsh environments.
Armored re resistors are usually composed of armored platinum thermal resistance temperature sensing elements, mounting fixtures and wiring devices, etc. Features: less thermal response time, reducing dynamic errors; small diameter, unlimited length; high measurement accuracy;
Imported thin film resistor elements, reliable and stable performance;

Working principle Armored thermal resistance measures the temperature of a substance when its temperature changes. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value.
