Gauge needle

Needle gauge is mainly applied to the rolling stock used to measure the hydraulic system or the storage cylinder pressure; can be used for brazing copper alloy non-corrosive, non-end product and solidification of both media pressure measurement. The instrument can simultaneously measure two identical or different (difference between the two is generally should not exceed the limits of the scale range is 1/3) of pressure. Structural principle Meter [1] consists of two separate measuring systems and indicating devices and other components. The working principle of the instrument is based on the elastic element (Bourdon tube measuring system) is elastically deformed. That is under pressure to be measured, so that the end of the two spring tube chase respective corresponding displacement produced by means of the rod through the gear transmission mechanism and to enlarge, the red fixed gear shaft, two are black pointer chasing is indicated on the measured values ??of the disk; main technical indicators accuracy class Environmental conditions temperature measuring range 1.5 5 ~ 60 ℃ relative humidity less than 80% of the use of temperature such as migraine 205 additional error is less than the temperature of 0.410 0-1000 , 1200,1600,2500kpa
