Spring manufacturer at the time of pressure measurement is in what way?
Believe that everyone is very curious, let us take you to look at!
Pressure measurement method contains: liquid pressure balance method, the elastic deformation principle balance method and electric logging three process, tightening
spring measuring pressure of three kinds of methods: 1.
Bourdon tube pressure gauges are working on the basis of elastic properties of elastic element.
Organized by spring tubes, mechanical transmission, amplification, pointer and dial, measured pressure by spring tube into the free end displacement, the displacement of mechanical drive organization into a pointer, after compared with scale can know the size of the measured pressure.
Bourdon tube pressure gauge structure brief, measurement and reliable, the price is low, is the use of scale wide, long history of on-site instruction type pressure surface before use.
2.
Strain type pressure sensor based on strain effect of measured pressure to complete the measurement.
By pressure adjustable element, strain gauge, chau bridge, flash surface composition, pressure adjustable element stress effect occurs after the corresponding strain E effect, the strain effect shows that resistance value changes, the measurement circuit is converted into voltage changes, by the size of the flash came out on the surface of measured pressure.
3.
Hall by bourdon tube type pressure sensors, hall effect device, flash surface, measured pressure by spring tube into a hole in the nonlinear magnetic field of displacement, the corresponding potential hall, the hall effect device output by the size of the flash came out on the surface of measured pressure.
4.
Capacitance pressure transmitter by the capacitive pressure adjustable components and conversion circuit, measured pressure through conversion components into capacitance of dynamic displacement, again through the capacitor into capacitance change of momentum, and the measuring circuit to detect the changes of capacitance, by the size of the flash came out on the surface of measured pressure.
Above is a time when spring manufacturer in spring pressure test used by the way, did you know?
