Accelerometers
- Electronic E/AA
|
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 |
