Industrial use of bimetallic thermometer dial and selection range

A thermometer is the floorboard of all measuring temperature instrument. Today we want to say is one of the kind of thermometer & ndash; — The bimetallic thermometer used in industry. It is mainly used to measure the temperature of the industrial equipment. So how to choose the industrial bimetallic thermometer watch brand and range? When it comes to industrial bimetallic thermometer range, due to the limitation of temperature sensing element, it can measure temperature range - commonly 50 - 500 c in the temperature of the liquid, gas or steam medium. General control error in the scale range + / - 1. About 5%. Industrial use of the bimetallic thermometer dial can customize according to the working temperature, can choose single range display or double range two kinds. Its scale is Fahrenheit and Celsius scale commonly used instructions. The Celsius scale ( C) With the Fahrenheit scale ( F) Definition of the difference between 0 degrees difference, under normal atmospheric pressure, will the freezing point of pure water as the 0 degrees Celsius, Fahrenheit will ice, water, the melting point of a mixture of ammonium chloride and sodium chloride as zero. From the bimetallic thermometer range is used in industry, its measuring the temperature of the object belongs to the low temperature, it has to do with the contact measurement method. Bimetallic thermometer used in industry have long heat pipe, heat element among them, it needs to be tested after a few seconds to a few minutes fully, good contact, just can get accuracy in 1. The temperature value of level 5.
