Ashcroft 351009 pressure gauge 304 SS 100 range 1.0 accuracy

Ashcroft 351009 gauge for industrial monitoring

This Ashcroft 351009 pressure gauge is built for industrial monitoring where a 1.0 percent accuracy class is specified. The 304 stainless steel case and polycarbonate lens resist corrosion in process environments. A 1/4 inch NPT male bottom connection fits standard piping without adapters. It suits technicians who need a dry, field-serviceable instrument for pressures up to 100.

Sustained load behaviour with liquid-filled damping

The liquid-filled design damps pointer vibration so readings stay steady under pulsating pressure or mechanical shock. Because the case is not field fillable, the fill fluid is sealed at the factory and will not leak during normal operation. The 304 stainless steel wetted parts maintain calibration when exposed to compatible media over long periods. No dry dampening feature is fitted, so the liquid fill carries the full damping duty.

Straightforward installation with common pitfalls

Thread the 1/4 inch NPT male connection directly into a matching female port using appropriate sealant for a leak-free joint. The bottom mount orientation requires clear space beneath the process connection for the gauge body. Over-tightening can distort the 304 stainless steel threads and cause leakage. The polycarbonate lens should be protected from solvents and impact during panel assembly.
