Overview
The NOSHOK PT20-150PSIG-1-1-2-14-ST8-CC is a bourdon tube pressure gauge designed for industrial applications. It features a 150 PSIG measurement range with a 2-1/2 inch dial diameter. The unit utilizes a 316 stainless steel wetted materials construction, including the case and bourdon tube, ensuring corrosion resistance. It employs a rear panel mount configuration with a 1/4 inch NPT lower connection. The gauge includes a liquid-filled chamber using glycerin to dampen vibration and provide internal lubrication for extended service life under dynamic conditions.
Feature Summary
- Liquid-filled design utilizing glycerin to absorb mechanical shock and reduce pointer oscillation during high-vibration operation.
- Constructed from 316 stainless steel for enhanced chemical compatibility and corrosion resistance in harsh environments.
- Rear panel mounting style allows for secure installation on control panels or enclosures without protruding into process spaces.
Applications
- Hydraulic systems requiring vibration damping
- Pneumatic equipment monitoring
- Industrial machinery with pulsating flow
- Process control panels
Procurement Notes
Verify that the specific model suffix matches the required connection size and material specifications for your application. Confirm the liquid fill type if operating in extreme temperature ranges, as standard glycerin may freeze at low temperatures. Ensure the process connection thread aligns with existing piping infrastructure before finalizing the order.
Selection Notes
Select this model when vibration isolation is critical for accurate reading stability. The 316 SS construction is preferred over brass for corrosive media. Consider the rear panel mount requirement versus front panel accessibility. Verify the pressure rating exceeds the maximum system working pressure to maintain safety margins.
Part Context
This instrument belongs to the NOSHOK PT series of bourdon tube gauges. These instruments are engineered for general industrial use where reliable pressure indication is necessary. The series offers various case sizes and connection options to accommodate different panel layouts and process requirements.
Replacement Considerations
Direct replacements must match the 1/4 NPT lower connection and 2-1/2 inch dial size. Cross-reference with other NOSHOK models such as the 25-510 series for similar performance characteristics. Ensure any substitute maintains the 316 SS wetted material specification for equivalent corrosion resistance.
FAQ
What is the purpose of the liquid fill in this gauge?
The glycerin fill dampens pointer movement caused by vibration and pulsation, protecting the internal mechanism from wear and improving readability.
Is the gauge suitable for oxygen service?
Standard models are not typically cleaned for oxygen service. Specific cleaning and oil-free configurations must be requested separately if intended for oxygen applications.
