Industrial gauge for 0-1000 psi systems

The Ashcroft 251009 measures pressure from 0 to 1000 psi on a 2 1/2 in dial. It suits technicians who need a direct-reading instrument for hydraulic or pneumatic circuits. The +/- 1.5 percent accuracy supports general industrial monitoring tasks. It is not for buyers who need a digital output or data-logging capability.

Stainless case with IP-rated vent plug

The 304 stainless steel case resists corrosion in harsh environments. An IP54 rating applies when the vent plug is open for pressure relief. Closing the plug raises the seal to IP65 and NEMA 4 for wash-down duty. Liquid filling dampens vibration so the pointer remains steady under continuous pulsation.

Bottom-mounted 1/4 in NPT connection

The male 1/4 in NPT thread screws directly into a port without an adapter. Bottom entry keeps the dial upright on horizontal piping runs. A polycarbonate lens protects the scale from impact. The case is field-fillable so liquid can be added or replaced on site.

Questions about this item

Does the IP54 vented plug let the gauge run quietly all day without overheating?

The gauge is a mechanical dial instrument with no fan or motor, so it produces no audible noise and generates no heat during continuous use.

What thread must my existing port have for the 1/4 in NPT male connection to seal properly?

The process connection is a 1/4 in NPT male thread; the mating port must be a 1/4 in NPT female thread.

Will the 304 stainless steel case and polycarbonate lens withstand the same vibration as my older liquid-filled gauge?

Yes, the gauge is liquid-filled for vibration resistance and the 304 stainless steel case with polycarbonate lens matches the durability of traditional liquid-filled models.
