How to measure the temperature of the liquid inside pipe

How to measure the temperature of the liquid inside pipe? Bimetallic thermometer can be used to detect pipeline inside the temperature of the liquid. Below small make up to introduce bimetallic thermometer for you. Bimetallic thermometer to two different linear expansion coefficient of metal together, one end fixed, when the temperature changes, the two different kinds of metal thermal expansion, drive the pointer to indicate the temperature, that is the bimetallic thermometer. Its principle structure is around into threaded thermal 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. Introduces for you below small make up a bimetallic thermometer: T221 a thermometer, product name: stainless steel, pointer thermometer thermometer, pipes, machinery, industrial thermometer thermometer thermometer using field: industry, petroleum, chemical industry, power engineering, pipeline, food, etc. Three, specification description: models: T221 types: hot shell bimetallic thermometer structure: axial type cover circle: flange type, tray type panel material: stainless steel SS304 tooth head: 1/4 & quot; The NPT, other optional surface diameter: 63 mm heat pipe diameter: 6. 35 mm heat pipe length: 150 mm ( 50 - Optional) around 1200 mm. Temperature range: 0 - 500C& F( Can be customized) Accuracy: & plusmn; 1. Table covered: 5% glass protection grade: IP65 four, product characteristics: corrosion SS304 pan and cover ring, the scene show temperature, intuitive and convenient; Safe and reliable, long life, fast reading. Five, the use matters needing attention: the thermometer when use should pay attention to clean up and check, regularly test the measured values. Six, the service is introduced: the series of thermometer is designed for installation in pipelines, ships, factories and machinery; The heat pipe and pan is 304 stainless steel material; In order to meet the characteristics of different devices, heat pipe length and the tooth is customized design and production process provides IP65 protection grade, can prevent the fog and moisture damage to the normal work of the thermometer.
