一、产品简介   Product Brief

    WZPK系列圆接插式热电阻是一种温度传感器，它比装配式铂电阻直径小，易弯曲，抗震性好，适宜安装在装配式铂电阻无法安装的场合。本公司生产的WZPK系列铠装铂电阻采用引进铂电阻测温元件，因此具有、灵敏、热响应时间快、质量稳定、使用寿命长等优点。

    WZPK series of armoured platinum resistor is a temperature sensor, It is better than the assembly type platinum resistance of small diameter, Easy to bend, Good earthquake resistance, Suitable for installation in Assembly type platinum resistance cannot be installed occasions. The company production of WZPK series of armoured platinum resistance With the introduction of platinum resistance temperature measuring element, So it has accurate, Sensitive, Fast thermal response time, Stable quality, The advantages of long life.

    WZPK系列圆接插式热电阻外保护套管采用不锈钢，内充满高密度氧化物资绝缘体，因此，它具有很强的抗污染性能和优良的机械强度，适合安装在环境恶劣的场合。

    WZPK series of armoured platinum resistance The outer protective sleeve made of stainless steel, Filled with high density oxidation material insulator, Therefore, It has very strong anti pollution performance and excellent mechanical strength, Suitable for installation in the harsh environment applications.

    WZPK系列可用于测量－200～+420℃范围内温度，可直接用铜导线和二次仪表相连接使用。由于它具有良好的电输出特性，可为显示仪、记录仪、调节器、扫描器、数据记录仪以及电脑提供的温度变化输入信号。

    WZPK series of armoured platinum resistance Can be used to measure－200～+420℃The range of temperature, Using copper conductor directly and two meter connected using. Because it has a power good output characteristics, For the display device, recorder, regulator, scanner, The data recorder And the computer to provide accurate temperature change of input signal.

二、工作原理   The working principle of:

    WZPK系列铠装铂电阻工作原理：在温度作用下铂电阻丝的电阻随之变化而变化。显示仪表将会指示出铂电阻产生的电阻值所对应的温度值。

    WZPK series of armoured platinum resistance The working principle of: Under the action of temperature The platinum resistance wire resistance change with change. Display instrument will indicate Platinum resistance The generated resistance value The corresponding temperature value.
