Steam and gas pressure type thermometer when use common attention should be paid to matters

Steam and gas pressure type thermometer when use common attention should be paid to the matters including the following: 1. The measured medium temperature package should be no corrosion. 2. Check whether the thermometer is through measuring department inspection, and in the period of validity. Reads and processes data should be combined with measurement department given temperature point revised accordingly. 3. Should choose the appropriate range of pressure type thermometer. Should make often indicate temperature in the range of about two-thirds or 3/4, observe so convenient reliable readings. For example, to measure the temperature of 70 ℃ or so medium, pressure type thermometer of the existing maximum range of 100 ℃ and the maximum range of 200 ℃ pressure type thermometer each one, then you should choose the former. 4. Header should be installed vertically in the absence of vibration plate. 5. Pressure type thermometer should insert the bulb all when use of the measured medium, and try to achieve maximum depth, lest affect measurement accuracy. If the bulb is only part of the measured medium, is due to the heat loss, the thermometer will show the temperature lower than actual temperature. But also can't go, will be part of the capillary tube inserted into the medium or heat medium in the capillary will because of the changes in temperature and make the temperature higher than the actual temperature thermometer. 6. Capillary pressure type thermometer shall not be affected by extrusion, and pay attention to keep clear of capillary. Such as the need to install the capillary tube bending, the bending radius should not be less than 50 mm, so that the temperature in the package of pressure can be measured quickly and accurately to institutions. 7. Considering the lag, pressure type thermometer should be stable after reading.
