The NOSHOK PT30-10000PSIG-1-1-50-18-ST8 is a high-pressure diaphragm seal pressure gauge designed for extreme industrial environments. It features a measurement range of 0 to 10,000 PSIG with a 4-inch dial diameter and an accuracy class of 1.5%. The unit utilizes a 316 stainless steel wetted material construction and includes a 1/2 inch NPT lower connection. A key specification is the 18-inch capillary length, which facilitates remote mounting from the process source.
Verify that the specified 18-inch capillary length aligns with the physical distance between the gauge location and the process tap. Confirm that the 1/2 inch NPT thread matches the existing panel or manifold interface. Ensure the 316 stainless steel wetted materials are compatible with the specific chemical properties of the measured medium to prevent corrosion or contamination.
Select this model when standard bourdon tube gauges cannot withstand the 10,000 PSIG operating pressure or when the process fluid requires isolation. The choice depends on the necessity for remote mounting due to environmental hazards. Evaluate if the 4-inch dial size provides adequate readability for the operator's viewing distance compared to smaller 2.5 or 3-inch alternatives.
This instrument belongs to the NOSHOK PT series of diaphragm seal pressure gauges. This line is engineered specifically for applications involving high pressures, elevated temperatures, or clogging fluids. The design integrates a sealed diaphragm element connected to the gauge movement via a capillary system, distinguishing it from direct-mount pressure indicators.
Public confirmed substitute part numbers: None.
