1, the application of the bimetallic thermometer bimetallic thermometer apply to live in low-temperature detection, direct measurement of liquids, gases and steam temperature, a mercury-free harm, the instructions clear, strong, resistant to vibration. All instruments of stainless steel materials, has a good waterproof, decay resistance performance. It is widely used in petroleum, chemical, metallurgical, textile, food and other industries. Can be directly measured in the process of various production - 80℃- Liquid + 500 ℃ range steam and gas medium temperature. 2, the characteristics of the scene display temperature, intuitive convenient safe and reliable, long life many kinds of structure forms, can meet the different requirements of 3, the working principle of double metal thermometer is based on the ring around the made of bent bimetallic strip. End is heated expands, turns the pointer, the instrument will show thermoelectric potential should value. 4, main technical parameters of product standards: JB/T8803 - 1998; GB3836- Dial 83 nominal diameter: 60, 100, 150, precision grade: 1. 0 and 1. 5 thermal response time: 40 s or less protection grade: IP55 Angle adjustment error: error of Angle adjustment shall not exceed the range of 1. 0% return difference: the thermometer shall not return difference more than the absolute value of basic error limits repeatability: the thermometer repeatability limit scope shall not cut more than 1/2 basic error limits the absolute value of
