In every DP transmitter application, there must be some means of connecting the transmitters pressure-sensing ports to the points in a process. Metal or plastic tubes (or pipes) work well for this purpose, and are commonly called impulse lines, or gauge lines, or sensing lines.
How does pressure differential transmitter work?
The most common and useful industrial pressure measuring instrument is the differential pressure transmitter. This equipment will sense the difference in pressure between two ports and produce an output signal with reference to a calibrated pressure range. It will have two pressure ports marked as “High” and “Low”.
What does a pressure transducer do?
A pressure transducer is a measuring device which converts an applied pressure into an electrical signal. Generally, a pressure transducer consists of two parts, an elastic material that deforms under the application of pressure and an electrical part that detects this deformation.
How do you create a differential pressure?
Differential pressure, in general, is a measure of pressure where the reading and reference values are variable. Differential pressure is calculated by subtracting one of these values from the other. If Pipe A flows at 100 psi and Pipe B flows at 30 psi, the differential pressure would be 70 psi.
How do I choose a pressure transducer?
When selecting a pressure transducer, keep these five criteria in mind:Application and measurement type. Common type of pressure measurement include: Absolute, gauge, differential, vacuum, bidirectional, and sealed gage. Pressure range. Process media. Temperature range and installation environment. Accuracy. Output.

How do you calculate differential pressure?
Differential pressure, in general, is a measure of pressure where the reading and reference values are variable. Differential pressure is calculated by subtracting one of these values from the other. If Pipe A flows at 100 psi and Pipe B flows at 30 psi, the differential pressure would be 70 psi.
Why is differential pressure important?
Differential pressure refers to the difference in air pressure from one location to another within a system. In cleanrooms, maintaining the right amount of differential pressure—either positive or negative—is essential to preventing contamination.
What does pressure differential mean?
Differential pressure is essentially the difference in pressure between two given points. It is a type of pressure measured within different industries using differential pressure sensors. Differential pressure is more complex than Gauge or Absolute pressure as it has two variables.
