A03E01

The A03E01 is a uniaxial capacitive MEMS accelerometer with true DC response, so it measures static acceleration, tilt and slow motion as well as vibration. A variable-capacitance MEMS element with internal AC excitation and demodulation outputs a differential voltage signal proportional to acceleration, and with 20 mV/g sensitivity and a ±200 g range it is the highest-range model in the family, with ±200 g and 2 kHz bandwidth for overload, impact and high-level road-load events. Typical uses include overload and crash-pulse testing, vehicle road-load data acquisition on suspension and chassis, drop and impact events and high-level low-frequency vibration.

The response is flat within ±5% from DC to 2 kHz, with ≤ 0.2% transverse sensitivity and 0.1% typical non-linearity (0.3% max), a ±4 V full-scale output and noise of 678 µg/√Hz over 0 – 100 Hz. It runs from any 6 – 30 VDC supply with low power consumption and survives 5,000 g pk shock. The laser-welded titanium-alloy HEX 16 × 15 mm housing weighs 10 g, is sealed to IP68, and carries a 1/4-28 4-pin connector with the signal ground isolated from the housing and an M5 stud mount (10-32 optional).

True DC response

Capacitive MEMS sensing measures from 0 Hz, so static tilt, sustained acceleration and slow motion are captured alongside vibration to 2 kHz. Resonance 11 kHz, transverse sensitivity ≤ 0.2%, non-linearity 0.1% typical.

Low-noise MEMS chip

An industry-leading capacitive DC-response MEMS chip gives 678 µg/√Hz noise over 0 – 100 Hz and 9.8 mg rms broadband resolution, with a differential ±4 V full-scale output that runs straight into a voltage-input DAQ from a 6 – 30 VDC supply at low power.

Rugged sealed titanium

Laser-welded HEX 16 × 15 mm titanium-alloy housing sealed to IP68, weighing 10 g, rated to 5,000 g rms vibration and 5,000 g pk shock and −55 to +125 °C. Signal ground isolated from the housing, 1/4-28 4-pin connector and M5 stud mount at 3.0 N·m.
