Digital Pressure Gauges
Compared with traditional analog pressure gauges, digital pressure gauges offer a wider range of signal outputs and remote transmission capabilities, allowing users to monitor pressure readings from a distance more efficiently.Depending on application requirements, specifications such as large displays, high accuracy, digital contacts, and RS485 communication can be selected. In addition to these standard options, SJ Gauge also provides customized digital pressure gauge solutions tailored to specific operational needs.If you have any special requirements, please feel free to contact us.

Digital Pressure Gauges FAQ
Common selection questions for digital pressure gauges, including output signal, accuracy, data logging, corrosive media, and customization.
How do I choose a digital pressure gauge for my application?
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.
When should I choose RS485 or 4-20mA output?
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.
Which digital pressure gauge is suitable for pressure calibration?
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.
Can digital pressure gauges record pressure data?
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.
Are digital pressure gauges suitable for corrosive media?
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.
Which models are commonly used for HVAC or low differential pressure monitoring?
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.
Can SJ Gauge customize digital pressure gauges?
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.
