- **Caution**: 
- **Caution**: 

### Q: Why is stainless steel construction important for pressure gauges in food manufacturing?
**A**: Stainless steel provides corrosion resistance, easy cleaning, and meets food safety standards by preventing contamination in hygienic environments like starch processing systems.

### Q: How does this pressure gauge maintain accuracy in continuous starch hydrocyclone operations?
**A**: The Bourdon tube sensing element and precision movement mechanism ensure reliable pressure readings despite constant operation, while tempered glass protects the dial from moisture and cleaning chemicals.

### Q: What makes this gauge suitable for hydrocyclone separator applications?
**A**: With brass/bronze fittings for secure connections and a design that withstands vibration and pressure fluctuations, it provides stable monitoring essential for efficient starch separation processes.
