Differential pressure transmitter

Differential Pressure Transmitter:

• Function: A differential pressure transmitter measures the difference in pressure between two points.
• Reference Point: It compares the pressure at one point to the pressure at another point (often across a restriction or orifice).
• Applications:
  • Flow measurement (using Bernoulli’s principle).
  • Level measurement (e.g., in tanks or vessels).
  • Filter monitoring.
• Output Signal: Similar to pressure transmitters, it provides a 4-20 mA HART.
