Overview
WZ series industrial thermal resistors are used as temperature measurement sensors. They are usually used in conjunction with temperature transmitters, regulators and display instruments to form a process control system to directly measure or control various processes. The temperature of liquid, steam, gas medium and solid surface in the range of -200℃-500℃ during the production process.
Thermal resistance uses the characteristic that the resistance of the substance changes when the temperature changes. To measure temperature. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the medium within the range of the temperature sensing element.
Although the shapes of various thermal resistors vary greatly. , but their basic structures are roughly similar, generally consisting of temperature sensing elements, insulating sleeves, protective tubes, and junction boxes.
Features
·Compression spring type sensor Temperature element, good anti-vibration performance;
·High temperature measurement accuracy;
·High mechanical strength, good voltage resistance;
·Imported thin film resistor components , reliable and stable performance.
Working Principle
Thermal resistance uses the characteristic that when the temperature of a substance changes, its resistance also changes to measure temperature. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value.
