Overview of Handle type armored thermocouple

Handle type armored thermocouple, hand-held digital display thermocouple, hand-held digital display meter is a thermocouple used to measure the surface temperature of various shapes of solid media and the temperature of liquid and gas. Hand held thermocouple has a wide range of applications and is not limited by the shape of the object surface. It is light and convenient to carry. Because the hand-held thermocouple has small diameter, bendable, anti vibration, fast thermal response time, fastening and durability High reliability surpasses the advantages of platinum rhodium thermocouple. This product can directly measure and display the temperature of various media within the range of 0~1200 ℃ in different production processes when used with a digital display instrument. At present, handheld thermocouples are widely used in metallurgical, chemical, textile, printing and dyeing, papermaking, rubber, plastics, ceramics, granaries and other industrial departments and enterprises.

Working priciple of Handle type armored thermocouple

The two ends of two conductors with different components are welded to form a loop. The direct temperature measuring end is called the measuring end, and the terminal is called the reference end. When there is a temperature difference between the measuring end and the reference end, a thermal current will be generated in the circuit. Connect the display instrument, and the instrument will indicate the corresponding temperature value of the thermoelectric EMF generated by the thermocouple. The thermoelectric EMF of the sheathed thermocouple will increase with the temperature rise at the measuring end. The magnitude of the thermoelectric EMF is only related to the conductor material of the sheathed thermocouple and the temperature difference at both ends, and has nothing to do with the length and diameter of the thermoelectric electrode. The structure of armored thermocouple is made of conductor, insulated magnesium oxide and 1Cr18Ni9Ti stainless steel protective tube by drawing for many times. Armored thermocouple products are mainly composed of junction box, terminal and armored thermocouple, and are equipped with various installation and fixing devices.

Thermal response time of Handle type armored thermocouple
In case of step change in temperature, the time required for the output of the thermocouple to change to 50% of the step change is called the thermal response time, which is represented by t0.5.
The thermal response time of armored thermocouple shall not be greater than that specified.
