WSS - 381 the performance of the bimetallic thermometer structure

WSS - 381 bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. WSS - Bimetallic thermometer can be directly measured 381 - in the process of all kinds of production 80℃- Liquid + 500 ℃ range steam and gas medium temperature. WSS - 381 main components of bimetallic thermometer is one with two or more pieces of metal laminate composed of multilayer metal together, using two different metal working in the principle of expansion degree of different temperature changes. WSS - Bimetallic thermometer is based on the 381 round made ring bending shape of bimetallic strip. End is heated expands, turns the pointer, the instrument will show thermoelectric potential should value. WSS - 381 bimetallic thermometer can cooperate with various casing installation, satisfies the requirement of different pressure levels. Can be directly measured in the process of various production - 80 ~ + 500 ℃ within the scope of liquid, steam and gas medium, as well as solid surface temperature measurement. WSS - 381 bimetallic thermometer using two different temperature expansion coefficient of metal, welding in fixed point at one end, on the other side when the temperature distortion, converts it into a pointer deflection Angle, indicating the temperature. WSS - 381 double metal thermometer, adopting the core-pulling structure bimetallic temperature sensing element can be drawn from the external protecting tube, if instrument damage need to change, don't have to cool, step-down or downtime, simply replace the table core. WSS - 381 bimetallic thermometer is given by upper and lower contacts, set temperature range, when the temperature reaches a given value, the dynamic and static contact closure, send electrical signals, thereby the purpose of automatic control and alarm. WSS - 381 bimetallic thermometer is a kind of suitable for measuring the temperature of the testing instrument, can be used to directly measure the temperature of the gas, liquid and steam. WSS - 381 bimetallic thermometer is widely used in machinery, shipbuilding, petrochemical, metallurgical, power, light industry and scientific research departments and so on. WSS - 381 bimetallic thermometer compared with industrial glass mercury thermometer, a mercury-free harm, easy reading, solid and the advantages of resistance to vibration, can use it to replace the fragile industrial glass mercury thermometer. WSS - 381 bimetallic thermometer can cooperate with various casing installation, satiety different pressure levels. Can directly measure various - in the process of producing 80 - + 500 ℃ within the scope of liquid, steam and gas medium and solid appearance temperature measurement. WSS - 381 bimetallic thermometer is made of round shape into threaded heat dual metallic piece as temperature sensing element, and put it in a protective sleeve, one end fixed ( Fixed end) And the other end, The free end) Connection on a thin shaft, shaft end is equipped with a pointer. When the temperature changes, temperature sensing element of the free end immediately rotation, thus fine axis pointer to produce angular displacement, indicates that the change in temperature on the dial; Straight table by steering transmission mechanism to drive a pointer. Due to the heat element has a linear relation with temperature changes, so the WSS - 381 bimetallic thermometer pointer indicated by the location of the measured temperature value is. Watchcase material with steel, cast alloy, stainless steel plate; Detecting element also have core-pulling structure; Adjustable Angle the header part of the thermometer with the aid of the corrugated pipe, Angle of body parts, such as you can from the Angle to the straight or from the straight to the Angle at any Angle.
