Bimetallic thermometer range

Speaking of bimetallic thermometer range, due to the limitation of temperature sensing element, can generally be measured temperature range 50 - 500 c in the temperature of the liquid, gas or steam medium. General control error in the scale range + / - 1. About 5%. Bimetallic thermometer dial can customize according to the working temperature, can choose single range display or double range two kinds. Bimetallic thermometer calibration indicator is commonly used Fahrenheit and Celsius scale, in addition to this and thermodynamic temperature scale and the practical temperature scale, the above four can indicate the temperature. The Celsius scale ( ℃) With the Fahrenheit scale ( ℉) 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. Fahrenheit and Celsius conversion formula: C = 5/9 ( F - 32) Calculate a calculate how many degrees Fahrenheit equals more than? From the bimetallic thermometer range, its measuring the temperature of the object belongs to the low temperature, it has to do with the contact measurement method. Bimetallic thermometer has 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 0. 1 - The temperature of the 1st level instructions. The above said good contact specific what things? Good contact with the analyte thermal components in after almost does not affect the temperature of the object; The temperature of the object to be tested is lower than the thermal component of analyte can limit and not corrosion thermal components. Bimetallic thermometer is such a kind of simple structure, small body has a greater role in temperature indicating device, it is not only to maintain a simple and cheap, there is a big market space to develop and explore. Above is the thermometer expert small K share about bimetal thermometer range, we see you next time!
