Pressure Measurement Trainer

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
• The whole system is self-contained with all accessories included
• The instrument is enclosed in a tapered fiberglass box and all necessary test points are brought out with schematic circuitry for understanding the working of the instrument
• The system operates on 230V AC Supply
