Bimetallic thermometer when use should pay attention to what time is it?

Bimetallic thermometer is a kind of low temperature field temperature measurement instrument. It can be directly measured various - in the process of production 50 ℃ ~ + 500 ℃ temperature range of liquid, steam and gas. It is widely used petrochemical, hvac equipment, industrial equipment, power plants, etc. He said it in the use of bimetallic temperature below timing should pay attention to the points. Bimetallic thermometer is in use process should pay attention to the following: 1. Bimetallic thermometer heat tube immersed in the measured medium length must be greater than the length of the thermal components, generally greater than 100 mm in length, 0 50 ℃ range into greater than 150 mm in length, so as to ensure the accuracy of measurement. 2. Bimetallic thermometer should not be used to measure open containers within the medium temperature, electric contact thermometer colorful vibration at work used in the control circuit of big occasions. 3. Bimetallic thermometer in custody, use the installation and transportation, should avoid collision protection tube, do not make the protection tube bending variant and the table when the spanner is used. 4. Thermometer in the case of normal use shall be regularly test, is every six months. Electric contact thermometer is not allowed to work under strong shock, so as not to affect the reliability of the contact. Bimetallic thermometer, widely used under the condition of high mechanical strength requirements. And have waterproof, corrosion resistance, vibration resistance, intuitive, easy reading, no mercury pollution, strong and durable, etc. Alternative to many other forms of thermometer table, widely used in petroleum, chemical industry, machinery, ships, electricity, textile, printing and dyeing and other industrial and scientific research departments.
