              Summary
              Armored thermocouple has many advantages, such as being able to bend, resistant to high pressure, fast thermal response time and durable. Like the industrial assembled thermocouple, it is used as a transmitter for measuring temperature, usually in combination with the display instrument, recording instrument and electronic regulator, and also as a temperature sensing element of the assembled thermocouple. It can directly measure the temperature of liquid, steam, gas medium and solid surface in the range of 0 ~ 800 ℃.
              principle
              The working principle of armored thermocouple is that the two ends of two different components of conductor are welded to form a circuit, and the direct temperature measuring end is called the working end, and the terminal end is called the cold end, also known as the reference end. When there is a temperature difference between the working end and the reference end, a thermal current will be generated in the circuit. When the display instrument is connected, the corresponding temperature value of the thermoelectric EMF generated by the thermocouple will be indicated on the instrument.
              The thermoelectric force of the armored thermocouple will increase with the temperature of the measuring end. The thermoelectric force is only related to the material of the thermocouple conductor and the temperature difference between the two ends, and has nothing to do with the length and diameter of the thermoelectric pole.
              The structure principle of armored thermocouple is that it is made of conductor, high insulating magnesium oxide and 1Cr18Ni9Ti stainless steel protective tube, which has been pulled together for many times. Armored thermocouple products are mainly composed of junction box, terminal and armored thermocouple, and equipped with various installation and fixing devices.
              Armored thermocouple is divided into two types: insulation type and shell type.
              Basic technical indicators


              Note: 1. T is the absolute value of the measured temperature


              2. T-type graduation products need to be ordered through consultation with the manufacturer


              Thermal response time of armored thermocouple


              In case of step change of temperature, the time when the output of thermocouple changes to 50% of the step change is called thermal response time, which is expressed by τ 0.5.


              insulation resistance


              When the ambient air temperature is 20 ± 1.5 ℃ and the relative humidity is not more than 80%, the insulation resistance between the coupling wire of insulated armored thermocouple and the outer sleeve shall meet the requirements of the following table.


              Deflection


              The radius of flexible curvature of armored thermocouple shall not be less than 5 times of its outer diameter.

              Note: the nominal total length L of 1 ¢ 3 insulated armored thermocouple shall not be greater than 10000mm.


              2. The outer diameter of armored thermocouple is d < 5mm, and there is splash proof or waterproof junction box. Users should pay attention to that when installing the thermocouple, the exposed part of the equipment must be equipped with support and other auxiliary supports to increase the rigidity, ensure the firmness, prevent the junction box from shaking back and forth, and damage the thermocouple.


              structure


              Structure form of armored thermocouple material


              Structure form of working end (hot end)


              Installation and fixation form


              The fixture is for user installation. In addition to the products without fixed device, the armored thermocouple fixed device has four structural forms: fixed ferrule type, movable ferrule type, fixed flange and movable flange. The fixed ferrule type is used for the user to fix in a short time, and the movable ferrule type user can fix for many times.

              Note: the numbers in brackets are generally not used as specifications. If special specifications are needed, order.


              Free end (junction box) type of armored thermocouple


              The junction box is used to connect the free end of the thermocouple and the display instrument. At present, there are many types of structures, such as simple type, splash proof type, waterproof type, handle type, small junction box type and compensation conductor type.
