Typical applications for the Model 1410 include microcomputer controlled applications, such as automotive airbags, active suspension, adaptive brakes, and security systems; fuzing; shipping recorders; appliances; vibration measurement and analysis, and machinery control.
The test and measurement devices offer low power consumption and high long-term bias stability (1000 PPM typical), which makes them suitable for use within low current applications consuming 2 milliamps with 5 volts excitation.
The Model 1410 uses a clock frequency between 100 KHz and 1.0 MHz and produces a pulse density output relative to acceleration. Units are available in seven standard ranges, from plus-or-minus 2g to plus-or-minus 200g, with sensitivities from 0.625 kHz/g (200 g range) to 62.5 kHz/g (2 g range).
Frequency response is from 0 to 400 Hz (plus-or-minus 2 g) to 0 to 2000 Hz (plus-or-minus 200 g) at fixed intervals according to selected g range, responding to DC (continuous) and dynamic acceleration. A MEMS VC accelerometer design enables the Model 1410 to withstand mechanical shock inputs to 5000 g (2000 g on low range units -- 2g and 5g FSO) without damaging the unit. All units are serialized for traceability and quality control. Custom ranges are available.
Design of the Model 1410 incorporates the Silicon Designs proprietary MEMS sensing element, which has constant nitrogen damping over its full operating temperature range of -55 to 125 degrees Celsius. Each unit is hermetically sealed in a miniature package measuring 0.36 by 0.35 by 0.165 inches, terminating in either a 20-pin LCC or JLCC type connector.
This makes them suitable for placement on circuit boards, in small packages, or for OEM applications. The digital output signal of the Model 1410 is compatible with TTL/CMOS devices.
