B00Y54

The B00Y54 is a watertight three-axis IEPE accelerometer built on a piezoelectric ceramic shear structure with a wide-band frequency response. With 1 mV/g sensitivity and a ±5,000 g range it is the highest-range model in the family, with ±5,000 g for shock and impact events on submerged or wet structures. Typical uses include underwater shock and impact testing, marine and offshore structures under wave and slamming loads, hull and propulsion shock and high-level vibration in humid or flooded environments.

A one-piece vulcanized 6-pin polyurethane cable withstands longitudinal and transverse water pressure above 3 MPa and is inherently resistant to moisture and corrosion, so there is no connector to flood. The built-in low-impedance circuit sits inside a double-layer shielded construction that isolates the signal ground (≥ 10⁸ Ω) for strong interference immunity, low noise and a well-behaved temperature response. The laser-welded low-density titanium-alloy 27 × 27 × 15 mm housing weighs 60 g, uses memory-alloy fasteners for a stable, reliable structure, and bolts down through two M4 through-holes.

Sealed for immersion and corrosion

Laser-welded titanium housing sealed to IP68 with a one-piece vulcanized cable rated above 3 MPa in both directions and inherently resistant to moisture and corrosion. Rated to 6,000 g rms vibration and 10,000 g pk shock, −50 to +120 °C.

Three axes, double shielded

Simultaneous X, Y and Z from a single 27 × 27 × 15 mm block with ≤ 5% transverse sensitivity. Double-layer shielding isolates the signal ground (≥ 10⁸ Ω) and rejects interference on long cable runs to the surface.

Built for high levels

Shear-mode ceramics with a ≥ 30 kHz resonance and a ≤ 0.5 s discharge time constant handle ±5,000 g events cleanly. Built-in IEPE circuit with 2–20 mA excitation and 8–12 V bias, spectral noise of 400 µg/√Hz at 100 Hz and 0.01 g rms broadband resolution.
