The use of the bimetallic thermometer maintenance

Bimetallic thermometer is a kind of special measure - 50/550 c field instruments, wide use. Use also is very convenient, as long as it's heat pipe insert can be measured medium. If you want to take longer to use it, the necessary maintenance is necessary. We sort out the matters needing attention in operation and maintenance of bimetallic thermometer: 1, bimetallic thermometer in custody, installation, use and transportation process, should try to avoid collision protection tube, don't make the protection tube bending, deformation. When installation, it is forbidden to twist the instrument shell. 2, instrument should be in - Within the environment temperature 25 ℃ ~ 55 ℃ to work normally. 3, temperature instrument often work better in the scale range of 1/2 to 3/4 place. 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 deformation and torsion meter directly. 7, thermometer in the case of normal use shall periodically 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.
