的特点： First, the characteristics of assembled thermal resistance :
1.High temperature measurement accuracy;
2. Spring-loaded temperature-sensing component with good anti-vibration performance;
3. High mechanical strength and good pressure resistance;
4. Imported thin film resistor components, reliable and stable performance.
2. The following two points must be noticed when using assembled thermal resistance:
1. The division number of the thermal resistance and the display instrument must be the same;
2. In order to eliminate the influence of the resistance change of the connecting wire, a three-wire connection method must be used.
Usually used in conjunction with display instruments, recording instruments, etc. Fabricated thermal resistance directly measures the temperature of liquid, steam and gas medium and solid surface in the range of -200 ～ 500 ℃ during production.
● Pressure spring type temperature sensing element, good anti-vibration performance;
● High measurement accuracy;
● High mechanical strength and good pressure resistance;
● Imported thin film resistance elements, reliable and stable performance;
Prefabricated thermal resistance measures the temperature of a substance when its temperature changes. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value.

Model and simple overview of assembled thermal resistance
Prefabricated thermal resistance is produced by Jinhu Dongxiang Instrument Co., Ltd. Industrial prefabricated thermocouples as temperature transmitters are usually used with display instruments, recording instruments and electronic regulators. It can directly measure
Surface temperatures of liquids, vapors and gaseous media and solids ranging from 0 ° C to 1800 ° C in various production processes.
Available models: B, S, K, E
Detailed introduction of assembled thermocouple
Jinhu Dongxiang mainly produces primary instruments such as thermocouples and thermal resistors, and the assembled thermocouples produced adopt international IEC standards. At the same time, the series and pattern spectrum of the thermocouples uniformly designed by the Ministry of Machinery and Electronics Industry are adopted.
