Ashcroft 451279 Process Pressure Gauge 0 to 5000 psi

The Ashcroft 451279 is a process pressure gauge built for industrial measurement tasks. It provides a primary pressure range of 0 to 5000 psi with an accuracy of +/- 0.5 percent. The phenolic case and glass lens suit demanding environments. Dry vibration-dampened PLUS! Performance handles mechanical shock without liquid fill.

Check NPT connection size and mounting orientation

Verify that your system uses a 1/2 in male NPT process connection at the bottom entry point. The gauge is field fillable no, so it arrives ready for dry operation. Ensure the phenolic case material and glass lens are compatible with the process media and ambient conditions. The case colour is black with a white dial for clear reading.

Sustained load behaviour with dry dampening

Under continuous pressure cycling the dry dampened PLUS! Performance resists pointer flutter without glycerine fill. The phenolic case maintains structural integrity across the 0 to 5000 psi span. Vibration resistance remains consistent because there is no fluid to leak or degrade over time. Accuracy stays within +/- 0.5 percent during extended service intervals.

Questions about this item

Does the gauge come with any fittings or adapters for the 1/2 in NPT male connection?

The gauge has a 1/2 in NPT male process connection; mating fittings or adapters are not included and must be sourced separately.

Is the 0.5 percent accuracy figure the only specification to consider, or are there other variants?

The listed accuracy is +/- 0.5 percent of span with a dry PLUS! Performance dampened case; no other accuracy grades or dampening options are described for this model.

What does the +/- 0.5 percent accuracy mean when the gauge reads near 5,000 psi?

At full scale the reading can deviate by up to half a percent of the 5,000 psi range, so the true pressure may be above or below the indicated value by that margin.
