Industrial Pressure Monitoring

The Ashcroft 251009 pressure gauge is built for technicians and engineers who need reliable 0 to 200 psi readings in process and hydraulic systems. Its diaphragm seal isolates the sensing element from corrosive or viscous media. The 2-1/2 inch dial with polycarbonate lens provides clear visibility in plant or field environments. Accuracy is rated at plus or minus one percent of span.

Panel And Line Integration

A lower back 1/4 inch NPT connection allows direct mounting on panels or tight piping runs without extra fittings. The stainless steel case and 316SS socket and tube resist chemical attack and vibration. Polycarbonate lens and stainless steel ring protect the movement from impact and wash-down. Operating range spans minus 40 to 150 degrees Fahrenheit for outdoor or heated lines.

Sustained Load Behaviour

Under continuous pressure the diaphragm seal prevents process fluid from entering the bourdon tube, eliminating clogging and drift over time. The 2 psi graduation remains readable during long shifts without parallax error. Series 1009 construction maintains calibration through thermal cycles from minus 40 to 150 degrees Fahrenheit. Five year manufacturer warranty reflects confidence in long term stability.

Questions about this item

At what pressure will the 200 psi range stop reading accurately?

The gauge is calibrated to +/-1% accuracy across the full 0 to 200 psi scale, so sustained use at the upper end stays within that tolerance.

Will the polycarbonate lens or 316SS tube degrade when running continuously at 150 °F?

Both materials are rated for the full -40 to 150 °F operating range, so all-day operation at the top temperature limit will not cause heat-related failure.

Does the 1/4" NPT lower-back connection need a special seal or adapter to install?

It mates directly with standard 1/4" NPT fittings; the integral diaphragm seal is already assembled, so no extra sealing components are required.
