双金属温度计的分类及选型须知
1、分类
  按双金属温度计指针盘与保护管的连接方向可以把双金属温度计分成轴向型、径向型、135°向型和万向型四种。     
        ①轴向型双金属温度计:指针盘与保护管垂直连接。 
  ②径向型双金属温度计:指针盘与保护管平行连接。
     ③135°向型双金属温度计:指针盘与保护管成135°连接。 
  ④万向型双金属温度计:指针盘与保护管连接角度可任意调整。
2、双金属温度计的安装固定形式
  为了适应实际生产的需要,双金属温度计具有不同的安装固定形式:可动外螺纹管接头、可动内螺纹管接头、固定螺纹接头、卡套螺纹接头、卡套法兰接头和固定法兰。
3、双金属温度计型号命名方式

Classification and selection of bimetal thermometers 1. Classification, bimetal thermometers can be divided into axial type, radial type, 135-direction type and universal type according to the connection direction between the dial and the protective tube. 1 Axial bimetal thermometer: The dial is vertically connected to the protective tube. 2 Radial bimetal thermometer: Pointer Plate and protective pipe parallel connection. 3135 directional bimetal thermometer: dial is 135 connected to protective tube. 4 universal bimetal thermometer: Pointer disc and Protective Tube Connection Angle can be arbitrarily adjusted. 2. Installation and fixing of bimetallic thermometers, in order to meet the needs of actual production, bIMETAL thermometers are available in a variety of mounting and fixing modes: external screw couplings, internal screw couplings, fixed screw couplings, snap-on screw couplings, snap-on flange couplings and fixing flanges. 3. BIMETAL thermometers type named as type W S □□□□ as protective form non-common type, fixed type W protection type 0-non-fixed device f-corrosion type, structural type 1-movable external thread 0-axial type 2-movable internal thread 1-radial type 3-fixed thread 2-1354-fixed thread 3-universal type 5-clip thread, case nominal diameter 6-clip Flange 3-604-1005-125 temperature sensor is bimetal, metal expansion, temperature instrument
