WZP-620 WZP2-620 WZP-630 WZP2-630 Assembly RTD

Overview of WZP-620 WZP2-620 WZP-630 WZP2-630 Assembly RTD

Assembly thermal resistance as temperature measurement sensor, usually display instrument, recorder and electronic regulator supporting use, according to the national provisions of assembly thermal resistance production should conform to IEC international standard grading number Pt100 platinum thermal resistance and conform to professional standard grading number Cu50 copper thermal resistance assembly type, unified design type thermal resistance which is fixed thread cone type, Spray type, waterproof type, diameter: 16mm

Working principle of WZP-620 WZP2-620 WZP-630 WZP2-630 Assembly RTD

It has many advantages, good decomposition of parts, convenient maintenance, low cost to replace wearing parts
Electrical signals, high sensitivity, stability, interchangeability and accuracy are better. The normal temperature insulation resistance of platinum thermal resistance should not be less than 100M ω, and the normal temperature insulation resistance of copper thermal resistance should not be less than 50M ω. Widely used in petroleum, chemical and other production site accompanied by a variety of flammable, explosive gas, steam occasions.
WZ series industrial thermal resistance as, usually with the temperature transmitter, regulator and display instrument supporting the use of process control system, to directly measure or control a variety of production process within the range of -200℃-500℃ liquid, steam and gas medium and solid surface temperature.
Thermal resistance measures temperature by using the property that the resistance of a substance changes with its temperature. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the medium where the temperature sensing element is located.
Although the shapes of various thermal resistors vary greatly, their basic structures are generally similar, consisting of temperature sensing elements, insulating bushings, protective tubes, and junction boxes.

Features of WZP-620 WZP2-620 WZP-630 WZP2-630 Assembly RTD

Thermal resistance is measured by the characteristic that the resistance of a substance changes with its temperature
Measure the temperature. When the resistance value changes, the working instrument will display the temperature corresponding to the resistance value.
Assembled thermal resistance is composed of temperature sensing elements, outer protective tubes, junction boxes and fixed devices for various purposes. There are two specifications of single and double components. The protective tubes not only have corrosion resistance, but also have enough mechanical strength to ensure that the products can be safely used in various occasions. Temperature measurement principle: the resistance of the heated metal wire changes with the change of temperature, and the relationship between its thermoelectric resistance value R(t) and its temperature t can be expressed as :R(t)=R0(1+At+Bt2+......) , the temperature value t can be obtained by checking the corresponding thermometer according to the measured resistance value.
