PRESSURE GAUGES
All pressure gauges are calibrated and tested:
100% helium leak tested
100% calibrated against the master – NIST traceable standards
Our goal is to deliver the best gauge solution to every customer, every time. Whether
it’s a new application that involves R & D brainstorming or calibration for an instru-
ment, it’s likely that QED has already built a gauge that meets or exceeds your requi-
rements. Select from our aerospace pressure gauges.

ACCURACY Tested by the same methods as master gauge builders QED specialists will assist you in selecting the level of accuracy that best suits your application.

VIBRATION Meets MIL-G-25867 and testing parameters for RTCA DO 160 and Mil-Std-810. Approved for “equipment installed in propeller airplanes and equipment mounted to engines including jet engines”. Special designs tested to 90 gRMS overall.

SHOCK Shock–tolerant designs to withstand loads up to 100Gs.

ENVIRONMENT Meets MIL-G-25867 for humidity, salt, fog, fungus, dirt, over-pressure, endurance, seasoning, temperature-altitude, high and low pressure extremes Custom environmental testing is available for RTCA DO 160, Mil-Std-810 and many others.

TEMPERATURE QED gauges have been tested to -65 degrees F/ -54 degrees C and + 257F(+120C), so they’re built to withstand the most severe temperature fluctuations . Meets requirements for MIL-G-25867.

COIL Fabricated from Inconel X-750 on custom built, QED-designed CNC equipment. Compatible with most fluids. Extremely durable, Non-magnetic. Excellent oxidation and corrosion resistance with a very high modulus of elasticity. Beryllium Copper Bourdon coils also available.

LONG LIFESPAN QED gauges are designed to outlive the systems into which they are installed. Each unit is a custom-designed piece with engineering that’s unique to each installation.

IN-HOUSE CNC MACHINING & PROGRAMMINGISO 9001 certification and quality control system ensures that component parts conform to specs. In-house facility managers oversee every step of the process, keeping on-time delivery QED’s highest priority.

CASE Materials are matched to the application. For example, aluminum for light-weight needs, and 300 Series CRES for corrosion resistance or strength. QED fabricates all materials on CNC turning centers.

LENS Chose the material that best suits your application. QED can supply glass crystals or fabricate plastic lenses in its factory on QED designed, purpose-built machinery. Acrylic (Plexiglas) delivers superb clarity, and is resistant to scratches and UV, while polycarbonate (Lexan) offers greater strength.

FITTINGS Hundreds of different styles and sizes in corrosion-resistant, high-strength 300 Series
stainless steel or other materials to suit your needs. All fittings are manufactured in-house to exacting industry standards on our state-of-the-art CNC machines. You can order back-mount, top-mount or bottom mount…the choice is yours.
