PT20-30PSIC-1-2-2-25-ST8

Overview

The NOSHOK PT20-30PSIC-1-2-2-25-ST8 is a diaphragm seal pressure gauge designed for industrial process monitoring. It features a 2.5-inch dial with a 0 to 30 PSI measurement range, providing clear visual indication of system pressure. The unit utilizes a stainless steel wetted materials construction to ensure durability and resistance to corrosion in demanding environments. A standard bourdon tube mechanism transmits pressure changes to the pointer, while the integrated diaphragm seal isolates the internal movement from potentially clogging or corrosive media. This configuration supports reliable performance across various fluid applications.

Feature Summary

• Diaphragm seal isolation protects the internal gauge mechanism from corrosive or viscous process media
• Stainless steel wetted components provide enhanced corrosion resistance and structural integrity
• Standard bourdon tube operation ensures accurate pressure transmission and stable pointer movement

Applications

• Chemical processing systems requiring isolation from aggressive fluids
• Pharmaceutical manufacturing processes involving sanitary or sticky media
• Industrial piping networks monitoring low-pressure liquid flows

Procurement Notes

Verify that the specific model number matches the required pressure range and connection type for your application. Confirm material compatibility between the diaphragm seal and the process fluid to prevent degradation. Ensure the mounting orientation aligns with the specified back or bottom connection style. Request certification documents if traceability is required for quality assurance protocols.

Selection Notes

Select this gauge when process media requires isolation from the sensing element due to viscosity or corrosiveness. The 30 PSI range suits low-pressure applications where precise visual monitoring is necessary. Stainless steel construction is preferred for environments demanding hygiene or chemical resistance. Consider the dial size for visibility requirements in the installation area.

Part Context

This component belongs to the NOSHOK PT series of diaphragm seal pressure gauges. The series is engineered for industrial applications where direct contact between the process fluid and the gauge internals must be prevented. These instruments combine standard pressure indication with robust sealing technology to extend service life in challenging conditions.

Replacement Considerations

When replacing this unit, ensure the new gauge matches the original pressure range, connection thread size, and wetted material composition. Verify that the diaphragm seal design accommodates the same process media characteristics. Cross-reference with NOSHOK's official substitution list for compatible alternatives.
