1. Pressure Range and Accuracy
Select a gauge that matches your required pressure range. For best performance, the operating pressure should be within 30–70% of the full-scale range.
High-quality industrial digital pressure gauges offer:
- ±0.5% FS accuracy (or better for calibration)
- Stable readings over long-term use
- Support for both positive and vacuum pressures
2. Display and Usability
A clear LCD display improves field and workshop usability. Look for:
- Backlit, easy-to-read screens
- Multiple pressure units (bar, psi, MPa, kg/cm²)
- Peak hold and auto zero functions
These features are especially useful for portable digital pressure gauges and in industrial maintenance applications.
3. Construction and Environmental Protection
Choose gauges made from stainless steel or robust materials for durability. Features to consider:
- IP65/IP67 waterproof and dustproof
- Corrosion-resistant wetted parts
- Shock-resistant housings
These ensure reliable operation in industrial, hydraulic, and HVAC systems.
4. Output Options and Integration
For system monitoring or automation, consider gauges with output signals:
- 4–20 mA or 0–10 V analog
- RS485 / Modbus (optional models)
These allow integration with PLCs or SCADA systems and support industrial process monitoring.
5. Supplier Reliability and Bulk Supply
When sourcing digital pressure gauges for wholesale or OEM, consider:
- Stock availability and delivery lead time
- OEM customization options
- Technical support and calibration services
Partnering with a reliable supplier ensures consistent quality and stable supply.
Conclusion
When buying a digital pressure gauge, prioritize accuracy, pressure range, display quality, durability, and supplier reliability. Selecting the right gauge improves system performance and reduces operational costs.
