You know what inside the pointer thermometer?

Pointer thermometer and bimetallic thermometer, in industry, petroleum, chemical industry, heating system, pipeline, power plants, Marine and other industries and fields widely used. Its working principle is to round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. Today we could lead to a universal type of bimetallic thermometer ( A300 - 1) As an example to introduce structure of pointer thermometer. Description: specifications: A300C - 1 ( WSS3B825150) Type: hot shell bimetallic thermometer structure: universal type cover circle: flange type, tray type panel material: stainless steel SS304 tooth head: 1/2 & quot; NPT other optional surface diameter: 80 mm heat pipe diameter: 6. 35 mm heat pipe length: 150 mm ( 50 - Optional) around 2000 mm. Temperature range: 0 - 150 c F ( Can be customized) Accuracy: & plusmn; 1. Table: 5% glass protection grade: IP65 ( Dust, water) Product features: the scene display temperature, intuitive and convenient; Safe and reliable, long life, fast reading. Use notice: the thermometer when use should pay attention to clean up and check, regularly test the measured values. Service is introduced: the product can rotate 180 degrees Angle observation, in order to meet the characteristics of different devices, parameters such as heat pipe length and the teeth can be customized.
