FAQ
- A process pressure gauge is designed for tougher industrial service than a utility gauge. Stainless case (or coated steel), solid-front safety design, blowout back, fluid-filled for vibration damping, and higher accuracy class (typically 0.5%). Built to take the temperature, vibration, and chemical exposure of refining, chemical, and oil and gas plant service. Costs more, lasts longer, fails safely.
- A solid-front safety case has a steel partition between the Bourdon tube and the dial face. If the tube fails and process fluid flashes into the case (which happens with hot or hazardous fluids), the partition contains it and the blowout back ruptures away from the operator. Standard equipment on process gauges; not on utility gauges. Required by code on many hazardous services and a good idea on any line that could hurt someone if the gauge fails.
