What is a digital differential pressure gauge? In this article, VCR will provide the basics of this differential pressure gauges. Let’s find out!

1. What is a digital differential pressure gauge?

Digital differential pressure gauge is a device used to measure the difference in air pressure from one location to another within a system.

In purification industry, digital differential pressure gauge is mounted outside cleanroom, to measure the pressure inside and outside cleanroom.

When compared to mechanical differential pressure gauges, digital differential pressure gauges take advantage of available technology to provide more features, better performance, and a more accurate and complete product.

2. Digital differential pressure gauge features

  • Various measuring ranges: 0-60 pa, -60-60pa, 0-250pa, 0-500pa, 0-750pa
  • Weight: 600gr/pieces
  • Max pressure: 3 PSI (0.2 bar)
  • Working environment: -20~+85°C
  • Protection: IP65
  • Accuracy: ±2.0% FS ; for range 0-60 pa, the accuracy is 4.0% FS
  • Connection: 1/8” ports (high-pressure ports and low-pressure ports), two pairs (on left side and back)

3. Differential pressure gauge working principle

Digital differential pressure gauges working principle is different from mechanical differential pressure gauges. The AC and DC power supplies play a major role in digital differential pressure gauges. The switching circuit or AC is converted to DC. The pressure is measured and sent to the sensor diaphragm, which senses the pressure, based on which an electrical signal is generated to reach the computer or smartphone. These gauges have a small LCD display.

4. Differential pressure gauge applications

Digital differential pressure gauges are widely used to measure the pressure of fan and blower, air velocity, pressure drops across orifice plates, liquid levels with bubbler systems, and pressures in fluid amplifier or fluidic systems.

This digital differential pressure gauge is commonly used in chemical processing, oil refineries, gas liquefication, power plants, pharmaceutical manufacturing, food production, and industrial processes. It assists in flow measurement and filter monitoring.

Digital differential pressure gauges are used in many industrial and manufacturing sectors, such as Pharmaceutical cleanroom, food processing cleanroom, HVAC, hospital cleanroom, laboratories, and many other fields…
