industrial production of thermal resistance thermocouple how to distinguish? this station for you.
At the beginning, introduce the industrial production of thermal resistance. Although the industrial production of thermal resistance is widely used in industrial production, its application is undoubtedly limited because of its temperature detection range, but it does not need platinum thermal resistance, and it is even better than real-time hot spots. The basic concept of temperature detection of the heating resistor is based on the characteristic that the resistance value of an electric conductor or a semiconductor device changes with a change in temperature. It also offers numerous advantages: it can transmit electrical signals over long distances, boasts high sensitivity and strong reliability, exhibits good interchangeability and accuracy, and is capable of measuring temperature changes in an instant. Industrial production grade thermal resistance generally use Pt100,Pt10,Cu50,Cu100, platinum thermal resistance temperature detection range is generally 210-350 degrees Celsius, copper thermal resistance is 40 to 250 degrees Celsius.
secondly, introduce blackbody temperature controller . platinum thermal resistance is the most widely used temperature electronic device in temperature measurement. its main characteristics are wide inspection scope, relatively stable characteristics and simple structure, the dynamic reply is good, and the data signal of 4-50 m A electronic device of water meter can be transmitted wirelessly, which is beneficial to the automatic control system and centralized automatic control system.
platinum thermal resistors currently used globally have a standard specification. globally, thermocouples are divided into several different detection ranges, namely B,R,S,K,N,E,J and t, and their measured temperatures range from 0 to 1500 degrees celsius. among them, B,R and S belong to thermocouples of platinum product series. since platinum belongs to precious metals, so they also called noble metal thermocouples and the remaining several called cost-effective metal composite thermocouples. Thermocouples come in two structural types: the installation type and the armored cable type. The installed thermocouple is generally composed of thermoelectric factory grade, insulating tape, maintenance of flexible waterproof sleeve and terminal block, while the armored cable thermocouple is a solid combination manufactured by Latin after installation of the three-liability insurance of thermoelectric heating wire, cable sheath raw material and metal composite material maintenance of flexible waterproof sleeve.
because electronic thermostat electronic device data signals must be transmitted through a different power line, which is called platinum thermal resistance. Different types of thermocouples must have different platinum thermal resistors. Its important role is to connect with thermocouples to avoid power transformers at the control end of thermocouples, thus stabilizing the temperature at the control end. Platinum thermal resistance is divided into two types: compensation type and lifting type. The composition of lifting power line is the same as that of thermocouple to be compensated. However, in practice, lifting power line is not a metal composite material with the same raw material as thermocouple, and is generally replaced by power line with the same electronic energy level as thermocouple. The wiring of a platinum resistance thermometer to a thermocouple is usually quite straightforward: the positive terminal of the thermocouple is connected to the red wire of the platinum resistance thermometer, while the negative terminal is connected to the remaining wire. General temperature controllers are mostly made of cobalt alloy.
