Dytran’s new generation of sensors combines two technologies (piezoelectric and DC response MEMS), which until now have never been packaged simultaneously in a single housing.

The Dytran model 7705A3 Extended Low Frequency (ELF™) accelerometer combines both a piezoelectric and a variable capacitance MEMS element, combined as a single output, to create the widest frequency response bandwidth in the industry, from DC (0 Hz) to 10 kHz. Unique ELF™ technology combines the most desirable features of piezoelectric sensors (excellent high frequency response) with those of variable capacitance accelerometers (true DC response), eliminating the need for using two different technologies to cover the bandwidth of interest in an application. Slow rotation speeds in the sub-1Hz range and gear mesh frequencies up to 10 kHz can now be made using the same sensor. The Dytran model 7705A3 ELF™ accelerometers are ideal for flight testing, ride quality, Health & Usage Monitoring Systems (HUMS), wind turbine measurements, machinery monitoring, and the widest range of structural response applications.

ELF™ accelerometer model 7705A3 is offered with a 20g range and operates on 5-28 VDC power at 7-9 mA of current. Signal/power is handled via a 4-pin M4.5 x 0.35 radial connector. The lightweight titanium housing weighs just 15 grams, and is hermetically sealed for use in rugged environments, from test tracks to outer space. The ELF™ incorporates a 10-32 tapped mounting hole and a hex base.
