Tiankang Analysis of Common Types of Thermal Resistance Temperature Transmitters
Thermal resistance temperature transmitter consists of reference unit, R/V conversion unit, linear circuit, reverse connection protection, current limiting protection, V/I conversion unit, etc. It is mainly used to detect various medium temperatures in the industry. What are the types of thermal resistance temperature transmitter ? The following Tiankang to specifically introduce the common types of thermal resistance temperature transmitter , and hope to help everyone.
1. Proficient in the structure and characteristics of the common thermal resistance temperature sensing element (resistor) in the industry. From the principle of temperature measurement of the thermal resistance, it can be seen that the change in the measured temperature is directly measured by the change in the resistance of the thermal resistor. Therefore, the change in the resistance of the lead wire, such as the thermal resistor body, will affect the temperature measurement. In order to eliminate the influence of the lead resistance, three-wire or four-wire systems are used in the same way.
2. The outer diameter of the armored thermal resistance armored thermal resistance is generally φ2~φ8mm, and the minimum is φmm. Compared with common type thermal resistance, it has the following advantages:
1 Small volume, no internal air gap, thermal inertia, low measurement lag;
2 good mechanical properties, vibration resistance, impact resistance;
3 can bend, easy to install 4 long service life.
3, the end of the thermal resistance of the end of the thermal resistance temperature sensor device by a special treatment of the resistance wire wound, close to the thermometer face. Compared with general axial thermal resistance, it can more accurately and quickly reflect the actual temperature of the tested end face, and is suitable for measuring the end face temperature of the bearing pad and other parts.
4. The flameproof thermal resistance flameproof type thermal resistance is limited to the junction box through the junction box with special structure, and the explosive mixture gas inside the shell is affected by sparks or arcs, and the explosion will not be induced at the production site. Flameproof RTDs can be used for temperature measurement in explosion-hazardous areas in Bla-B3c zones.
Anhui Tiankang will always adhere to the "TaiKang spirit of transcending excellence," and on the basis of creating a harmonious enterprise, it will continue to grasp the pulse of market development, actively seek economic strategic alliances, and continue to work for the revitalization of national industries. Welcome customers to negotiate.
