B00B72

The B00B72 is a uniaxial IEPE waterproof accelerometer with a built-in miniature impedance converter that turns the piezoelectric charge signal into a low-impedance voltage output. With 2 mV/g sensitivity and a ±2,500 g range it is the highest-range model in the family, a 9 g watertight cube with ±2,500 g and an 80 kHz resonance for underwater shock and high-level vibration. Typical uses include underwater shock and impact testing, high-level vibration on submerged or wet components, marine propulsion and washdown installations.

A one-piece vulcanized polyurethane cable with multi-layer protection is rated to water pressure above 2 MPa and is inherently resistant to moisture and corrosion, so there is no connector to flood. The built-in IEPE circuit runs from any 2–20 mA constant-current source with an 8–12 V bias. The laser-welded stainless-steel 8.5 × 8.5 × 10 mm housing weighs 9 g, is sealed to IP68 and mounts on an M3 thread with the supplied screws, with the cable exiting from the side. TEDS is available to order.

Sealed for immersion and corrosion

Laser-welded stainless-steel housing sealed to IP68 with a one-piece vulcanized PU cable rated above 2 MPa and inherently resistant to moisture and corrosion. No connector, no O-ring, nothing to flood. Rated to 3,000 g rms vibration and 7,000 g pk shock, −50 to +120 °C.

Built-in IEPE electronics

Shear-mode piezoceramic with a built-in impedance converter: ±5% response from 10 Hz to 8 kHz (±10% over 5 – 10k Hz), resonance ≥ 80 kHz, spectral noise of 200 µg/√Hz at 100 Hz and 0.005 g rms broadband resolution, straight into any IEPE input on the surface.

Tiny watertight cube

At 9 g and 8.5 × 8.5 × 10 mm, the B00B72 fits on small submerged components and adds almost no mass, mounting on an M3 thread with the supplied screws and a low side cable exit.
