This article will help you understand how to install a digital differential pressure gauge. Let’s find out!
There are 2 main types of differential pressure gauges: Mechanical and digital ones.
The differential pressure gauge installation method is the problem encountered by many engineers. Differential pressure gauges are one of the popular products of VCR. Digital differential pressure gauge P2000 is suitable for differential pressure applications with high requirements for pressure monitoring. A set includes LED display, button setting, sound alarm, input, output, etc.

Digital differential pressure gauge introduction
Features
- Using high-precision MEMS sensors and digital technology, it can detect positive pressure, negative pressure or differential pressure, and it can completely replace traditional mechanical differential pressure gauges.
- Diverse mounting method. It can be flush, surface, or wall-mounted.
- Various measuring ranges and units: 0-60 pa, -60-60pa, 0-250pa, 0-500pa, 0-750pa
- Accuracy up to 1%FS
- Weight: 600gr/pieces
- Max pressure: 3 PSI (0.2 bar)
- Working environment: -20~+85°C
- Protection: IP65
- Connection: 1/8” ports (high-pressure ports and low-pressure ports), two pairs (on left side and back)
Application
- 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.
- It can be used on medical equipment to monitor blood and respiratory pressure.
- Digital differential pressure gauges are used in many industrial sectors, such as Pharmaceutical cleanroom, food processing cleanroom, HVAC, hospital cleanroom, laboratories, and many other fields…
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.
Digital differential pressure gauge mounting
The digital differential pressure gauge mounting box made by inox 304 is commonly used with the gauges.

Pressure connection installation process
- Positive pressure measurement:
Connect the pipe to the hole “high pressure” at the back of the meter and block the other high-pressure hole.
Expose two holes “low pressure” to the atmosphere
- Negative pressure measurement:
Connect the pipe to the hole “low pressure” at the back of the meter and block the other low-pressure hole.
Expose two holes “high pressure” to the atmosphere
- Differential pressure measurement:
Connect the pipe to the hole “high pressure” at the back of the meter and block the other high-pressure hole.
Connect the pipe to the hole “low pressure” at the back of the meter and block the other low-pressure hole.
