The bimetallic thermometer operating instructions

1, the application of the bimetallic thermometer industrial 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 + 600 ℃ range steam and gas medium temperature. 2, the characteristics of the bimetallic thermometer display temperature, intuitive convenient mercury-free harm, safe and reliable, long life many kinds of structure form, wide scope of application, that can satisfy different requirement for - commonly 80℃- + 600 ℃ 3, the structure of the bimetallic thermometer 4, the working principle of bimetallic thermometer WSS series bimetallic thermometer is the use of two different metal working in the principle of expansion degree of different temperature changes. To improve the temperature measuring sensitivity, is usually made of metal spiral coil shape. When multi-layer metal temperature change, the layers of metal expansion or contraction, makes the spiral coil rolled up or let go. As a result of the spiral coil end fixed and the other end connected to a free rotating pointer, therefore, when the bimetallic strip feel the temperature change, Pointers can be on a circular dividing scale to indicate the temperature. 5, main technical parameters of product standards: gb, JB/T8803 - 1998; European standard EN13190:2001 e; American standard AMSE B40. 200 - Dial 2008 nominal diameter, 25, 28, 35, 44 and 50, 63, 80, 100, 120, 150 mm accuracy level: 1. 0 and 1. 5 protection grade: IP45, IP55, IP65 material: SS304, 316316 L6, temperature measurement range ℃ temperature measurement range, small - to adapt to the range of industrial and commercial laboratory 80 - +40√ √ - 40 - +80√ √ 0 - 50√ √ 0 - 100√ √ 0 - 150√ √ 0 - 200√ √ 0 - 300√ √ 0 - 400√ - 0 - 500√ - 7 work, normal atmospheric conditions workplace temperature ℃ relative humidity % shelter - 25 - + 555 - 100 - outdoor places 40 - + 855 - Note: 100 electric contact thermometer, atmospheric conditions for its normal work: - temperature 25 ℃ ~ + 55 ℃, relative humidity & le; 85%. 8, installation direction shown ( 1) Angle ( The axial type) Detecting element axis and perpendicular to the plane in the form of a dial, also known as axial type. ,( 2) Straight ( The radial type) Detecting element axis parallel to dial plane form, also called radial type.
