Ashcroft 4 1/2 in Process Compound Gauge

The Ashcroft 451379SSL04LVAC/30# is a process compound gauge built for industrial pressure monitoring. It covers a 30 to 0 to 30 psi range with a nominal dial size of 4 1/2 in and an accuracy of +/- .5 percent. The case is aluminium with a black finish and a glass lens.

Who This Gauge Suits

This gauge suits technicians who need a bottom-mounted, male NPT connection of 1/2 in and an IP66 or NEMA 4X rated enclosure. It is field fillable and uses liquid-filled vibration resistance with a white dial. Buyers who require a different pressure span, a smaller dial or a non-fillable dry case should look elsewhere.

Deciding Specification

The primary pressure range of 30 to 0 to 30 psi is the single figure that determines whether this gauge matches the application. If the process operates outside that compound vacuum and pressure window, the instrument will not read correctly.

Questions about this item

How do I verify the gauge is reading correctly after installation?

The gauge is calibrated to +/- 0.5 percent accuracy across the 30 to 0 to 30 psi range; compare its needle position against a known reference pressure to confirm it falls within this tolerance.

What components are included with the Ashcroft 451379 compound gauge and what must I supply?

The unit ships as a complete assembly with its aluminum case, glass lens and 1/2 in male NPT bottom connection; you must provide compatible process piping and any required thread sealant.

Which pressure range version should I select for vacuum and positive pressure up to 30 psi?

The 30 to 0 to 30 psi compound range covers both vacuum and pressure in a single instrument, so choose this model when your process spans that full span.
