Differential Pressure Sensor

Differential Pressure Sensor with pair of Strain Gauges

Determine the following:

  • Identify which port is the “high” pressure port
  • Identify what the voltmeter will register if fixed resistor R1 fails open
  • Identify a component fault that would drive the voltmeter full upscale (“peg” positive)
  • Identify another component fault that would drive the voltmeter full upscale (“peg” positive)

Answer:

Which port is the “high” pressure port: Port “B”

What will happen if fixed resistor R1 fails open: Voltmeter will drive fully upscale (“peg” positive)

Identify a component fault that would drive the voltmeter full upscale (“peg” positive):  as follows below

  • Strain gauge #1 fails shorted
  • Strain gauge #2 fails open
  • R1 fails open
  • R2 fails shorted
