Product Name: WSS series bimetal thermometer
Product Name: bimetal thermometer, thermometer, electric node bimetal thermometer, temperature measurement, Shanghai bimetal thermometer, Shanghai thermometer, Shanghai thermometer manufacturer, Shanghai bimetal thermometer manufacturer, protective metal protective sleeve thermometer, pipeline thermometer, magnet thermometer, electronic thermometer industry, customized thermometer, pointer bimetal thermometer ,
WSS series bimetal thermometer which good, first choice Shanghai Feilong. WSS series bimetal thermometers are suitable for the measurement of fluid temperature. When the temperature of industrial bimetal thermometers and electric node bimetal thermometers exceeds the set value, the output electric signal has reached the purpose of control.
When ordering bimetal thermometers, technical parameters such as product model, measurement range, installation thread, protection tube length, shell diameter and accuracy shall be indicated respectively.
1. Overview
The working principle of bimetal thermometer is to use two kinds of metals with different temperature expansion coefficient, one end is welded at the fixed point, the other end is twisted and deformed when the temperature changes, which is converted into the deflection angle of the pointer to indicate the temperature. The core pulling type refers to the bimetal temperature sensing element that can be extracted from the outer protective tube for replacement, and it is the most widely used on-site indicating thermometer. Bimetal thermometer is a kind of industrial instrument suitable for measuring medium and low temperature, which can be used to directly measure and display the temperature of gas, liquid and steam. The bimetal thermometer with live contact can automatically send out control signal to cut off the power supply or alarm when the industrial temperature exceeds the given value.
Bimetallic thermometers are widely used in ten power plants because of their advantages such as no mercury damage, easy reading, waterproof, anti-corrosion and vibration resistance. Machinery, chemical industry, textile, petroleum, food and other industrial and scientific research departments. Bimetal thermometer can be divided into three types: ordinary type, outdoor type and anticorrosive type. Its structure can also be divided into radial type, axial type, 135 ° type and universal type.

5、Use and maintenance
o ensure the accuracy of bimetal thermometer, the apparent length of the tail pipe immersed in the measured medium should be more than 75;
When reading, the line of sight shall be perpendicular to the dial;
After the thermometer is used for a period of time (generally 12 months), it shall be regularly verified according to the relevant verification regulations of industrial bimetal thermometer;
When the thermowell thermometer is damaged in use and needs to be replaced, just loosen the nut reversely, pull out the meter core, leave the protective tube in the equipment, install the new meter core, and tighten the nut.
In the process of transportation, storage, installation and use, the thermometer shall avoid colliding with the tailpipe as much as possible, and shall not be deformed or bent.
