Traditional Styling & Function… 21st Century TECHNOLOGY

Dial, pointers and reset are identical to the first generation accelerometer

New drive system moves the dynamic pointer smoothly and steadily through the entire range and works the tell-tale pointers with an authority not found on prior QED accelerometers or other competitive products

With no detectable hysteresis, the E/AA is more repeatable than similar cockpit accelerometers on the market today

 

 

Designed For Longevity & Performance

The new E/AA digital instrument is easier, less time-consuming & less expensive to manufacture.

With shorter lead times and lower calibration costs, QED/Inc. passes the savings on to its customers

Solid-state sensing and an electrical drive system dramatically improve reliability and maintainability, translating into lower life-cycle costs and improved user confidence in the values displayed

 

 

Traditional Mechanical versus Electronic Analog

Designed to completely replace the existing instrument

Envelope design and the materials in the exposed areas are identical to those in the original instrument

Mounting holes are unchanged for easy retrofitting

Two 28 VDC wires plus one ground wire for power differentiate the mechanical accelerometer from the new E/AA

 

 

We’ve Passed Every Test

Drive motors tested for more than 3.4 million cycles without one failure, ensuring longevity & reliability

Envelope design and the materials in the exposed areas are identical to those in the original instrument

Mounting holes are unchanged for easy retrofitting

Two 28 VDC wires plus one ground wire for power differentiate the mechanical accelerometer from the new E/AA
