What is a pneumatic gauge?

Pneumatic measuring instrument is a seat type and upper-mounted measuring instrument of the same length that can indicate the magnitude. Compared with the measuring tool, the measuring instrument has the advantages of high sensitivity, high precision, small measuring force, etc., and its structure is complicated. The measuring instrument has high requirements on environmental conditions and is generally used in the measuring room.

Measuring principle

Pneumatic measurement is the use of gas in the flow process, the change of certain physical quantities (pressure, flow, flow rate) through the gas-electric converter to convert the gas signal into an electrical signal and the light column display composed of the luminous tube to achieve a geometric quantity An instrument that uses this principle to measure is called a gas gauge.

Application field

Pneumatic measurement can achieve measurement items: inner diameter, outer diameter, groove width, two-hole distance, depth, thickness, roundness, taper, concentricity, straightness, flatness, parallelism, perpendicularity, air permeability and tightness. . Widely used in automotive, motorcycle, refrigerator air conditioning compressors, bearings, textile machinery, military, aerospace and other precision machining industries.
