Pressure gauges are precision measuring devices that visually indicate the exerted pressure by fluid or gas in a system. They are must-have tools in various industries and applications where accurate pressure monitoring is crucial. A pressure gauge typically features multiple components, such as a dial or digital display, a sensing element, and a mechanism to convert the pressure into a readable format. Moreover, they come in varied sizes, diameters, orientations, shapes, and types. In addition, pressure gauges are designed from different robust materials, ensuring long-lasting performance and resistance to harsh environmental conditions.
Materials of Pressure Gauges
Pressure gauges comprise various components, each made of different materials, depending on the gauge type, environment, and applications. The gauge case materials include stainless steel, brass, or plastics. Moreover, the gauge's dial case is made of aluminium or plastic. Additionally, the bourdon tube is constructed from phosphor bronze or Inconel.
Back Entry and Bottom Entry Pressure Gauges
Back Entry and Bottom Entry refer to the orientation of the pressure gauge's connection point, specifically where the pressure inlet is located on the gauge.
- Back Entry Pressure Gauge – In a back entry pressure gauge, the pressure inlet is located on the back or rear side of the gauge casing. This means the connection for measuring pressure is positioned at the back of the gauge, perpendicular to the dial face.
- Bottom Entry Pressure Gauge – The pressure inlet is located on the bottom of the gauge casing in a bottom entry pressure gauge. This means the connection for measuring pressure is positioned at the bottom of the gauge, parallel to the dial face.
What is the Difference Between Back Entry and Bottom Entry Pressure Gauges?
Both back-entry and bottom-entry pressure gauges measure pressure similarly, but their orientation allows for different installation configurations. The back entry design is commonly used when the pressure measurement is taken horizontally or from the backside of the gauge. On the other hand, the bottom entry design is typically used when the pressure measurement is taken vertically or from underneath the gauge.
