一、產(chǎn)品簡介   Product introduction

    微型熱電阻作為測量溫度的傳感器,通常和顯示儀表、記錄儀表和電子調(diào)節(jié)器配套使用。它可以直接測量各種生產(chǎn)過程中從-200℃~420℃范圍內(nèi)的液體、蒸汽和氣體介質(zhì)以及固體表面溫度。

    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.

    根據(jù)規(guī)定，我公司生產(chǎn)符合IEC標準分度號的Pt100、Pt1000鉑熱電阻和符合專業(yè)標準分度號的Cu50銅熱電阻兩大類組成兩大類裝配式、統(tǒng)一設(shè)計型熱電阻。

    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

    微型熱電阻,鉑熱電阻和銅熱電阻兩大類。

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

    微型熱電阻是利用物質(zhì)在溫度變化時自身電阻也隨著發(fā)生變化的特性來測量溫度的。熱電阻的受熱部分(感溫元件)是用金屬絲均勻地雙繞在絕緣材料制成的骨架上。當(dāng)被測介質(zhì)中有溫度梯度存在時，所測的溫度時感溫元件所在范圍內(nèi)介質(zhì)層中的平均溫度。

    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.

    微型熱電阻主要由接線盒、保護管、接線端子、絕緣套管和感溫元件組成基本結(jié)構(gòu)，并配以各種安裝固定裝置組成。

    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.

    微型熱電阻的感溫元件是一個鉑絲繞組，雙支鉑電阻主要用于需要用二套顯示、記錄或調(diào)節(jié)儀同時檢測同一地點溫度的場合。

    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型銅電阻的感溫元件是一個銅絲繞組。

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