Pressure Measurement Trainer

Pressure Measurement Trainer

The setup:

  • The setup comprises of air pump (Foot pump) to build pressure
  • A bourdon tube dial gauge will be fixed to the pressure chamber parallel to the pressure transducer
  • Pressure transducer is of diaphragm type on which strain gauges will be bonded

Display unit:

  • The display unit comprises of inbuilt power supply, Strain gauge signal conditioner, amplifier and Analog to Digital converter
  • The power supply provides power for signal conditioning and amplifiers, ADC and also for strain gauge excitation
  • The system provides front panel bridge balancing through potentiometer adjustment
  • The instrument is calibrated to read the pressure directly in Kg/cm2
