一、产品简介   Product introduction

    双支四芯热电阻元件作为测量温度的传感器,通常和显示仪表、记录仪表和电子调节器配套使用。它可以直接测量各种生产过程中从-200℃~420℃范围内的液体、蒸汽和气体介质以及固体表面温度。

    Industrial thermal resistance as a measurement of the temperature sensor, Usually, and display instruments, recording instruments and electronic supporting the use of regulator. It can be directly measured in various production processes From -200℃~420℃range of liquid, steam and gas and solid medium surface temperature.

    根据规定，我公司生产符合IEC标准分度号的Pt100、Pt1000铂热电阻和符合专业标准分度号的Cu50铜热电阻两大类组成两大类装配式、统一设计型热电阻。

    According to the provisions of the state, Our company in line with the IEC international standard index number Pt100, Pt1000 platinum thermal resistance And in accordance with the professional standards index number Cu50 thermal resistance two categories two kinds of assembly type, unified design thermal resistance.

二、工作原理   Working principle

    双支四芯热电阻元件,铂热电阻和铜热电阻两大类。

    The thermal resistance of industrial, platinum thermal resistance and thermal resistance of two kinds of.

    是利用物质在温度变化时自身电阻也随着发生变化的特性来测量温度的。热电阻的受热部分(感温元件)是用金属丝均匀地双绕在绝缘材料制成的骨架上。当被测介质中有温度梯度存在时，所测的温度时感温元件所在范围内介质层中的平均温度。

    Thermal resistance is when the temperature changes its resistance along with the characteristic changes of temperature measurement using the material. The thermal resistance of the heating part (temperature sensor) is made of metal wire even double wound on the insulating material on the skeleton. When measured in the medium temperature gradient exists, The average temperature of the measured temperature is the temperature of the components within the dielectric layer in the.

    装配式热电阻主要由接线盒、保护管、接线端子、绝缘套管和感温元件组成基本结构，并配以各种安装固定装置组成。

    Assembly type thermal resistance is mainly composed of a junction box, protection tube, terminals, the insulating casing and the temperature sensing element is the basic structure, And with a variety of mounting and fixing device.

    WZP型铂热电阻的感温元件是一个铂丝绕组，双支铂电阻主要用于需要用二套显示、记录或调节仪同时检测同一地点温度的场合。

    The temperature sensing element WZP platinum thermal resistance is a platinum wire winding, Double platinum resistance is mainly used to detect the same place temperature occasions with two sets of display, recording or regulator.

    WZC型铜电阻的感温元件是一个铜丝绕组。

    The temperature sensing element type WZC copper resistance is a wire winding.
