Overview
The NOSHOK PT20-30PSIG-1-1-2-8-ST8 is a precision bourdon tube pressure gauge designed for general industrial applications. It features a 2-1/2 inch dial with a measurement range of 0 to 30 PSIG. The instrument utilizes a stainless steel case and includes a liquid-filled movement, typically glycerin, to dampen vibration and protect internal components from wear. The process connection is a 1/4 inch NPT lower mount configuration.
Feature Summary
- Liquid-filled movement design effectively dampens needle oscillation and protects the mechanism from mechanical shock and vibration.
- Stainless steel case construction provides durability and resistance to harsh environmental conditions.
- Bourdon tube sensing element ensures accurate pressure indication across the specified measurement range.
Applications
- Hydraulic systems monitoring
- Pneumatic equipment instrumentation
- Industrial machinery pressure gauging
Procurement Notes
Verify that the specific model suffix corresponds to the required case material and fill fluid type. Confirm the process connection size matches the system interface. Ensure the pressure rating aligns with the maximum operating pressure of the application to maintain accuracy and safety standards.
Selection Notes
Select this gauge when vibration damping is critical for reading stability. The stainless steel case offers superior corrosion resistance compared to standard aluminum options. Ensure the 1/4 NPT connection fits the existing piping or manifold setup without requiring additional adapters.
Part Context
This model belongs to the NOSHOK PT series of bourdon tube pressure instruments. These gauges are engineered for reliability in demanding environments. The series is known for its robust construction and consistent performance in measuring non-corrosive gases and liquids compatible with wetted materials.
Replacement Considerations
When replacing an existing unit, verify the dial diameter, case style, and connection thread match the original specifications. Check if the previous gauge was liquid-filled to ensure equivalent vibration protection is maintained during the swap.
