Which WSS series bimetal thermometer is good is Shanghai Feilong. WSS series bimetal thermometers are suitable for measuring fluid temperature, industrial bimetal thermometers, and electric node bimetal thermometers. When the temperature exceeds a set value, the output electrical signal has reached the purpose of control.
When ordering bimetal thermometers, the product model, measurement range, installation thread, protective tube length, housing diameter, accuracy, and other technical parameters must be indicated separately.
The working principle of a bimetal thermometer is to use two metals with different temperature expansion coefficients. One end is welded at a fixed point, and the other end is distorted when the temperature changes, which is converted into a pointer deflection angle to indicate the temperature. The core-pulling type refers to the bimetallic temperature sensing element that can be pulled out of the outer protective tube and replaced. It is the most widely used field indicating thermometer. Bimetal thermometer is a kind of on-site testing industrial instrument suitable for measuring medium and low temperature. It can be used to directly measure and display the temperature of gas, liquid and steam. The bimetal thermometer with live contact can automatically send control signals when the industrial temperature exceeds a given value. Power off or alarm.
Bimetal thermometers have the advantages of no mercury harm, easy reading, waterproof, anti-corrosion, and anti-vibration. Machinery, chemical, textile, petroleum, food and other industrial and scientific research departments. The bimetal thermometer is divided into three types: ordinary type, outdoor type and anticorrosive type. From its structure, it can be divided into radial type, axial type, 135 ° type and universal type.

5, use and maintenance
◎ In order to ensure the accuracy of the bimetal thermometer, the length of the tail pipe immersed in the medium to be measured should be above 75 depending on the length of the medium;
◎ The line of sight should be perpendicular to the scale when reading;
◎ After using the thermometer for a period of time (usually 12 months), it should be regularly verified according to the relevant verification regulations of industrial bimetal thermometers;
◎ When the hot-sleeve thermometer is damaged during use and needs to be replaced, simply loosen the nut in the opposite direction, pull out the watch core, leave the protection tube in the device, install the new watch core, and tighten the nut.
◎ In the process of transportation, storage, installation, and use of the thermometer, avoid collision with the tail pipe as much as possible, and do not deform or bend it.
