Commercial Vacuum Gauge

This commercial vacuum gauge uses a bronze sensor and brass socket with a 1/4 NPT centre-back connection. The ABS plastic case holds a two-inch acrylic lens and the instrument is rated for an accuracy of +/-3-2-3 percent. It is designed for general test and measurement tasks where a panel-mountable unit is not required.

Upgrade from basic analogue gauges

The electronic design replaces simpler mechanical gauges that lack the stated +/-3-2-3 percent accuracy specification. The bronze sensor and brass socket combination suits applications needing those specific wetted materials. The jump is worth it when the process connection must be a 1/4 NPT male fitting in a centre-back orientation.

Handles vacuum measurement within stated accuracy

The gauge comfortably handles vacuum readings within the +/-3-2-3 percent accuracy band using the bronze sensor and brass socket. It runs out when an IP or NEMA environmental rating is required, as the unit carries no such rating. Hazardous location certification is also absent, limiting use to non-classified areas.

Questions about this item

What size NPT thread does the 1/4-inch brass socket need?

The gauge has a 1/4-inch male NPT process connection located at the centre back, so it threads directly into a matching female port.

How should the gauge be oriented when fitting the centre-back connection?

Apply thread sealant to the male NPT threads, tighten using a wrench on the brass socket flats, and avoid turning the ABS case to prevent damage.

What should be checked periodically on the bronze sensor and acrylic lens?

Inspect the acrylic lens for cracks or clouding and verify the bronze sensor connection remains leak-free; replace the gauge if calibration drift is suspected.
