  • Interfacing Pressure Sensors to Microchip's Analog Peripherals
    Pressure measurement devices can be classified into two groups: those where pressure is the only source of power and those that require electrical excitation. The mechanical style devices that are only excited by pressure, such as bellows, diaphragms, bourdons, tubes or manometers, are usually
  • Three Process Conditions That Affect Accuracy And Performance Of Pressure Gauges (.pdf)
    one of the most common methods of measuring pressure today. The majority of pressure gauges today still incorporate the bourdon tube, socket, and geared movement; along with a pointer and dial to indicate process pressure. Since the pressure gauge is a purely mechanical device, attention to three
  • Vacuum Measurements Introduction
    Deflection gauges measure true pressure via deflection of a bourdon tube, independent of the type of gas in a system. Bourdon tubes are constructed in either C-tube or helical coil geometries and of these two, helical Bourdon tubes provide the greatest sensitivity.
