The use of the bimetallic thermometer is introduced

The use of the bimetallic thermometer is introduced in the selection of the bimetallic temperature time, we must give full consideration to the practical application environment and requirements, such as the dial diameter, precision grade, fixed installation way, risk categories and measured medium environment, etc. In addition, also attaches great importance to the performance and maintenance workload and other factors. In addition, the bimetallic thermometer in use process should pay attention to the following: 1, the bimetallic thermometer protecting tube immersed in the measured medium length must be greater than the length of the thermal components, immersed in length is more than 100 mm, 0 50 ℃ range into greater than 150 mm in length, so as to ensure the accuracy of measurement. 2, all kinds of bimetallic thermometer should not be used to measure open containers within the medium temperature, electric contact thermometer should not be at work used in the control circuit of larger vibration 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, bimetallic thermometer in the case of normal use shall be regular inspection. 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. 5, the temperature of the instrument often work well in the scale range of 1/3 to 2/3.
