Vintage Brass Mechanical Pressure Guage
-
It measures pressure relative to the surrounding atmospheric pressure.
-
The gauge operates mechanically without needing electricity.
-
It uses a curved tube (Bourdon tube) that straightens under pressure, moving a pointer on a calibrated scale.
-
Pressure is displayed in units such as pounds per square inch (psi) or newtons per square meter (Pascals).
-
It is used in industrial, commercial, and process systems to monitor pressure in various applications.
-
Different types of pressure gauges exist for specific uses, like measuring absolute, gauge, or differential pressure.
- This particular gauge measures pressure up to 160 units, likely PSI.
