Structure principle

By the measurement system indicates the instrument section and housing components. The instrument has a good seal and a check seal means to protect its internal measurement mechanism from mechanical damage and contamination intrusion.

Action principle instrument is based on the elastic element (Bourdon tube measuring system) deformation under pressure measured medium, forcing the end of the spring tube to produce the corresponding elastic deformation - displacement, by means of the lever and the transmission gear mechanism to amplified by the fixed gear shaft will be measured by the value of the pointer is indicated on the indexing plate.

YB201251 precision pressure gauges

Precision pressure gauge is mainly used to check industrial pressure gauges and other common variety of instruments having a pressure parameters; can be used for precision measurement of non-corrosive media pressure.

Structure principle

Instrument from the measuring system, and the case indicating section section and other components.

Measuring system - consisting of the adapter, spring tube and gear rotating mechanism and other components.

Measured by the pressure of the media, so that the end of the spring tube (free end) corresponding displacement, with the rod driven institutions sector gears corner displacement, leaving the gear shaft can be deflected - pass indicator part.

Indicating portion - by the indexing plate, mirror (YB-201 type without mirrors and other components pointer by the pointer value of the deflection gear shaft on the corresponding sub-dial indicates the pressure value measured media.

Case part - by the table cover, table glass and the lower end of the cover housing and other components are provided for adjusting the zero position with zero means zero value in order to maintain the accuracy and readings.
