The NOSHOK PT20-7500PSIG-1-1-2-25-ST8 is a high-pressure diaphragm seal pressure gauge designed for extreme industrial environments. It features a 7500 PSIG measurement range with a 4-inch dial size and 316 stainless steel wetted materials. The unit utilizes a 25mm capillary length to isolate the sensing element from process media, ensuring accurate readings in corrosive or viscous applications.
Verify that the specified capillary length matches the installation distance between the process connection and the gauge location. Confirm that the diaphragm material compatibility aligns with the specific chemical composition and temperature of the process medium to prevent premature failure.
Select this model when standard bourdon tube gauges fail due to clogging or corrosion. Ensure the process temperature remains within the operational limits of the silicone fill fluid used in the sealed system. Validate that the 25mm capillary does not introduce excessive damping for dynamic pressure measurements.
This component belongs to the NOSHOK PT series of diaphragm seal pressure instruments. These devices are engineered for harsh conditions where direct contact with the gauge internals must be prevented. The series offers various wetted materials and fill options to suit diverse industrial demands.
Direct replacement requires matching the 25mm capillary length and 7500 PSIG range. Verify that the new unit supports the same 316 stainless steel wetted material specification to maintain chemical compatibility.
