Selecting a pressure Gauge
Adequate safety results from intelligent planning, careful selection and installation of gauges into a pressure system. The user should inform the supplier of all conditions pertinent to the application and environment so the supplier can recommend the most suitable gauge.
The pressure sensing element in most gauges is subjected to high internal stress, and applications exist where the possibility of catastrophic failure is present. Pressure regulators, chemical seals, pulsation dampeners or snubbers, siphons, manifolds and other similar items are available for usage in these potentially hazardous systems.
The potential hazard increases at higher operating pressure.
When selecting a pressure gauge, it is important to consider the following factors
to insure safety and accuracy.
