Sheathed thermoresistor

Product Introduction: The WZPK series armored thermistor is a commonly used temperature measurement sensor in industrial field. It features a small diameter, ease of bending, good toughness, and strong vibration resistance, making it suitable for installation in narrow pipelines and special situations requiring rapid response and miniaturization. It can also be used as the measuring element for assembled thermistors.

Product Description

The WZPK series armored thermoresistive sensors are commonly used industrial temperature measurement sensors. They feature a small diameter, ease of bending, good flexibility, and strong shock resistance, making them suitable for installation in narrow pipelines and special situations requiring rapid response and miniaturization. They can also be used as measuring elements for assembled thermoresistive sensors.

Sheathed thermistors measure temperature by utilizing the characteristic that the resistance of a material changes with temperature variations, and when the resistance changes, the working instrument displays the corresponding temperature value. They are commonly used with display meters, recorders, and digital regulators, etc., for temperature measurement, display, and control applications.

Operating Principle

Thermocouple resistance sheathed utilizes the characteristic that the resistance of a material changes with temperature variations to measure temperature. When the resistance changes, the working instrument displays the corresponding temperature value. The resistance sheathed thermocouple is a type of temperature sensor, which is smaller in diameter than assembled thermocouples, more flexible, and has better vibration resistance, making it suitable for installation in places where assembled thermocouples cannot be installed. The WZPK series resistance sheathed thermocouples adopt imported thermocouple temperature measurement elements, thus offering advantages such as high sensitivity, fast thermal response time, stable quality, and long service life.

The armored thermoresistor's external sheath is made of stainless steel, filled with high-density insulating material of oxidized substances. Consequently, the armored thermoresistor boasts excellent anti-pollution properties and mechanical strength, making it suitable for installation in harsh environments.

Features

The armored resistance external protective tube is made of stainless steel and filled with a high-density oxide insulating material, thus it boasts excellent resistance to contamination and mechanical strength, making it suitable for installation in harsh environments. The armored thermistor typically consists of the armored platinum thermistor sensing element, mounting fixtures, and wiring devices, etc., which feature a short thermal response time and minimize dynamic errors; it has a small diameter and the length is not subject to specific regulations.

High measurement accuracy;

Imported thin-film resistor elements, reliable and stable performance.
