High precision pneumatic instrument calibration device

1、 Introduction to SYFZ-15 Pneumatic Momentum Meter Calibration Device:

SYFZ-15 typeHigh precision pneumatic instrument calibration deviceIt is a specialized measuring tool for buoy type air momentum meters, used in metrology laboratories to calibrate buoy type air momentum meters. The pneumatic axial measuring head of the air momentum meter calibration device is a standard measuring nozzle, and a measuring block is ground on the upper micro motion block as a parallel baffle. When the differential device of the micro motion measurement platform is rotated, the upper micro motion block can be moved horizontally, and the corresponding displacement in the height direction can be obtained, which can change the gap at the end face of the measuring nozzle. The ratio of the distance between the displacement in the height direction and the displacement in the horizontal direction is 1:50. The two constitute the nozzle baffle mechanism, which is the basic component of pneumatic measurement.

2、 Characteristics of pneumatic momentum meter calibration device:

SYFZ-15 typeHigh precision pneumatic instrument calibration deviceThe relative movement of a pair of inclined wedges is used to adjust the measurement gap, which has high accuracy, is easy to use, and can be used at room temperature.

5、 Regarding the measurement principle of pneumatic measuring instruments:

The measurement principle of pneumatic measuring instruments is comparative measurement method. The measurement method is to convert the length signal into an airflow signal, which is indicated by a float in a graduated glass tube, called a float type pneumatic measuring instrument; Or by using a gas electric converter to convert the gas signal into an electrical signal, a light column indicator composed of light-emitting tubes is called an electronic column pneumatic measuring instrument. Pneumatic measuring instrument is a type of measuring instrument that can be assembled into multiple units. When paired with different pneumatic measuring heads, it can achieve the measurement of multiple parameters. Pneumatic instruments have been widely used in the mechanical manufacturing industry due to their many advantages.
