Common bimetallic thermometer use the matters needing attention

Bimetallic thermometer is used widely, and is often visible in our lives. Today, we summarize the matters needing attention of using bimetallic thermometer. 1, double metal thermometer in custody, installation, use and transportation process, should try to avoid collision protection tube, do not make. To protect the tube bending and deformation. When installation, it is forbidden to twist the instrument shell. 2, the bimetallic thermometer should be - 30 ℃ ~ 80 ℃ environment temperature in normal work. 3, the temperature of the bimetallic thermometer often work best to 1/2 to 3/4 in scale range. 4, bimetallic thermometer protecting 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. 5, 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. 6, 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. 7, 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.
