Industrial pressure gauge 0 to 400 psi

The Ashcroft 351009SWL02L400# is a new industrial pressure gauge with a 3-1/2 in dial and a primary range of 0 to 400 psi. It suits technicians who need a stainless steel instrument for general process monitoring. Buyers who require a digital readout or data logging should look elsewhere.

Thermals noise and power draw

The gauge is a mechanical instrument with no electrical supply, so it produces no noise and draws no power. Its 304 stainless steel case carries IP54 rating when the vent plug is open and IP65 plus NEMA 4 when the plug is closed. The polycarbonate lens protects the dial in normal plant environments.

Sustained load behaviour

Accuracy is rated at +/- 1.5 percent of span across the full 0 to 400 psi range. The case is field fillable with liquid to add vibration resistance for continuous service. A 1/4 in male NPT bottom connection secures the gauge directly into the process line.

Questions about this item

How do I install the 1/4 in NPT male bottom connection, and what step do people get wrong?

Thread the 1/4 in NPT male bottom connection into the process port using a wrench on the stainless steel hex; the step often missed is leaving the vent plug closed for IP65 or opening it for IP54 before pressurising.

What maintenance or replacement will the gauge need later?

The case is field-fillable; you can add or replace glycerine dampening fluid through the fill port to maintain vibration resistance without removing the gauge.

What limit appears first under sustained use at the top of the 0 to 400 psi range?

Accuracy is rated at ±1.5 % of span, so at 400 psi the reading can drift by up to 6 psi before any mechanical limit is reached.
