What is the working principle of the pressure gauge?
The models are different and the working principle is different1.WTY-1 - racy liquid pressure type thermometerThe model WTY liquid pressure thermometer utilizes the thermal expansion of a liquidA temperature, capillary, and Bourdon tube for measuring temperatureThe enclosed system is filled with a temperature measuring medium - liquid, when heatedWhen the temperature changes, the pressure in the closed system is due to the liquid bodyThe product changes as a result of a change in the curvature of the spring tubeThe displacement is generated by the end, and the pointer is driven through the connecting rod and the transmission mechanismTurn on the dial and indicate the temperature to be measured. This instrumentThe utility model has linear scale, small temperature package, fast reaction speed and sensitivityHigh, direct reading and other features, almost a collection of glass rod thermometer,Bimetallic thermometers, steam and gas pressure thermometersAdvantage, when the current application of the widest range of performance of the most comprehensive kindMechanical temperature measuring instrument.
The working principle of the pressure gauge:The pressure gauge through the sensitive element in the table (Bourdon tube, bellows, bellows) of the elastic deformation, then the conversion mechanism of table movement will transfer to the pointer pressure distortion caused by pointer rotation to show pressure.
