EGT K Type Thermocouple Exhaust Probe High Temperature Sensors Threads is a kind of temperature sensor. The braided thermocouple has many advantages such as bending, high pressure resistance, fast thermal response time and durability. It can measure the temperature of gas and steam. The armored thermocouple is the most widely used in temperature measurement. A wide range of temperature devices, his main features are wide temperature range, stable performance, simple structure, good dynamic response, and can remotely transmit 4-20mA electrical signals, facilitating automatic control and centralized control.
The armored thermocouple is a solid combination of thermocouple wire, insulating material and metal protective sleeve after being assembled and stretched. However, the electrical signal of EGT K Type Thermocouple Exhaust Probe High Temperature Sensors Threads requires a special wire for transmission. This wire is called a compensation wire. Different thermocouples require different compensation wires, the main function of which is to connect with the thermocouple, so that the reference end of the thermocouple is far away from the power supply, so that the temperature of the reference junction is stable. The compensation wire is divided into two types: compensation type and extension type. The chemical composition of the extension wire is the same as that of the compensated thermocouple. However, in practice, the extension type wire is not made of the same material as the thermocouple, and is generally used and thermoelectric. Instead of wires with the same electron density. The connection of the compensation wire to the thermocouple is generally clear. The positive terminal of the thermocouple is connected to the red line of the compensation wire, and the negative electrode is connected to the remaining color. Most of the materials for the compensation wires are made of copper-nickel alloy.
