| Armored thermal resistance |
是一种温度传感器，它比装配式热电阻直径小，易弯曲，抗震性好，适宜安装在装配式热电阻无法安装的场合，WZPK系列铠装热电阻采用引进热电阻测温元件，因此，具有精确、灵敏、热响应时间快、质量稳定、使用寿命长等优点。 Armored thermal resistance is a type of temperature sensor. It has a smaller diameter than assembled thermal resistance, is easy to bend, and has good shock resistance. It is suitable for installation where assembled thermal resistance cannot be installed. WZPK series armored thermal resistance adopts the introduction of thermal resistance to measure temperature. Components, therefore, have the advantages of accuracy, sensitivity, fast thermal response time, stable quality, and long service life. zzyfwh.com
The outer protective sheath of the armored thermal resistor is made of stainless steel and filled with high-density oxidizing material insulators. Therefore, the armored thermal resistor has strong anti-pollution performance and mechanical strength, and is suitable for installation in harsh environments.
Armored thermal resistance can be used to measure the temperature in the range of -200-600 ℃. It can be directly connected to the secondary instrument with copper wires. Since the armored thermal resistance has good electrical output characteristics, it can be used for display instruments, recorders, and regulators. , Scanners, data loggers, and computers provide accurate temperature changes.
工作原理：在温度作用下，热电阻丝的电阻随之变化而变化，显示仪表将会指示热电阻产生的电阻值所对应的温度值。 ● Working principle Working principle of armored thermal resistance : Under the action of temperature, the resistance of the thermal resistance wire changes accordingly, and the display meter will indicate the temperature value corresponding to the resistance value generated by the thermal resistance.
● Main technical indicators: Resistance value of thermal resistance temperature sensing element at 100 ° C (R100) and its resistance R0 ratio at 0 ° C: (R100 / R0)
