Electrical Pressure Measuring Devices

This was the presentations made by my college classmates in BSEE. Enjoy Reading!!!

1. Electrical Pressure Measuring devices Prepared by: ROMEO LUNA Jr.

2. Why Electrical Pressure Transducers? Has high accuracy than field pressure gauges. Transmission requirements for remote display as electric signal transmission can be through cable or cordless . Electric signals give quicker responses and high accuracy in digital measurements . The linearity property of the electric signal produced to pressure applied favors simplicity . They can be used for extreme pressure applications, i.e. high vacuum and pressure measurements.

3. Strain Gauge Pressure Transducer

4. Capacitive Pressure Transducer

5. C=ε0 εr A/d Where, C = the capacitance of a capacitor in farad A = area of each plate in m 2 d = distance between two plates in m εr = dielectric constant ε0 = 8.854*10^-12 farad/m 2

6. Potentiometric Pressure Transducer

7. Resonating Wire Pressure Transducer

8. Piezoelectric Pressure Transducer

9. Magnetic (LVDT) Pressure Transducer

10. Optical Pressure Transducer
