Question 1

How do I choose a digital pressure gauge for my application?

Accepted Answer

Start with the pressure range, accuracy requirement, pressure type, process media, installation environment, and whether you need local display only or remote output such as 4-20mA or RS485. For example, MXP is suitable for high-precision needs, PRD-S280C is useful when data logging is required, and MXT or PRD-FEF can be considered when remote signal output is needed.

Question 2

When should I choose RS485 or 4-20mA output?

Accepted Answer

RS485 is suitable when multiple devices need to communicate with a control system over a digital network. A 4-20mA output is a common industrial analog signal for stable remote transmission to PLCs, recorders, or monitoring systems. The best choice depends on the existing control architecture and required data format.

Question 3

Which digital pressure gauge is suitable for pressure calibration?

Accepted Answer

For calibration or reference measurement, select a high-accuracy digital pressure gauge with the appropriate pressure range and accuracy class. In this category, MXP and PRD-700 are better suited for precision measurement or calibration-related work than basic display-only gauges.

Question 4

Can digital pressure gauges record pressure data?

Accepted Answer

Yes. Models such as PRD-S280C are designed for automatic pressure data logging, while some models can record peak values or historical readings. These functions are useful for pressure tests, process monitoring, troubleshooting, and applications where readings need to be exported or reviewed later.

Question 5

Are digital pressure gauges suitable for corrosive media?

Accepted Answer

Corrosive applications require careful material selection for wetted parts and the housing. In this category, PRD-APP and PRD-DP are examples designed for corrosion-resistant requirements often seen in PCB or chemical-related processes. Always confirm compatibility with the exact process media before selection.

Question 6

Which models are commonly used for HVAC or low differential pressure monitoring?

Accepted Answer

For HVAC, filter, fan, duct pressure, or low differential pressure monitoring, models such as DRM108, TWM11, and TWM30 can be considered depending on the required output signal, display type, working mode, and pressure range.

Question 7

Can SJ Gauge customize digital pressure gauges?

Accepted Answer

Yes. SJ Gauge can provide customized digital pressure gauge solutions based on pressure range, accuracy, output signal, connection type, display requirements, and application environment. Share your operating conditions with the team so the most suitable configuration can be recommended.
