All kinds of liquid pressure type thermometer is introduced

Liquid pressure type thermometer is the use of the thermal expansion and contraction for temperature measurement, temperature, airtight system composed of capillary tube and spring - full of temperature measuring medium - Liquid, package feel the temperature changes when the temperature, the pressure inside the closed system for liquid volume change and change, cause spring tube displacement curvature changes to its free end, through the connecting rod and the transmission mechanism to drive pointer rotation, the table indicates the temperature being measured on the dial. This instrument has a linear scale, temperature, small volume, fast response, high sensitivity, intuitive reading etc, almost set the glass rod thermometer, bimetallic thermometer, all advantages of steam and gas pressure type thermometer, is currently the most widely applicable scope, when one of the most comprehensive mechanical performance measurement instrument. Liquid pressure type thermometer shockproof shockproof thermometer is in type wty thermometer developing, on the basis of its structure and working principle and pressure type thermometer are exactly the same, the difference is within the header is filled with oil liquid, to increase the damping of transmission parts and pointer. Shockproof thermometer for oscillations, such as high frequency and low frequency vibration occasion, such as compressors, diesel engine temperature measurement equipment, avoid caused by equipment vibration meter pointer jitter or mechanical damage, improve the service life of instrument. Liquid pressure type electric contact thermometer in type wty thermometer is installed on a contact device, through adjusting mechanism, can easily change set the position of the pointer. When the measured temperature rise ( Or falling) To the set point temperature of the opportunity to give an open or close the signal, is used to control, adjust or alarm temperature being measured.
