3 axes accelerometer

You get simultaneous, phase-matched data from three mutually perpendicular directions in a single housing. That avoids time-alignment issues and guarantees the axes are orthogonal right out of the box. It also simplifies mounting—you drill and bond one stud, not three.

For quasi-static measurements, you need a sensor with DC response—usually a MEMS capacitive model. We supply those with frequency response down to 0 Hz. The static gravity component on each axis gives you tilt angles. For dynamic vibration only, a standard IEPE sensor is fine.

We offer two approaches: a built-in IEPE charge amplifier so the low-impedance signal travels hundreds of meters on coax, or a 4-20 mA current loop for runs over a kilometer. The connector and cable shield termination are set up per your drawing; we can also pot a line-driver circuit inside the sensor body if space allows.

There’s always some crosstalk. Our calibration sheet lists the actual cross-axis sensitivity for each unit, measured on a shaker. Typical values are under 3%, which is low enough that it won’t smear mode shapes, but you can correct for it in post-processing if your software supports it.

Yes. We ship the accelerometer with a set of adapters: flat magnetic bases, curved magnetic blocks for pipes, and epoxy-mount studs with alignment jigs. If your surface has an unusual radius or material, we’ll machine a custom bracket from your sketch and include it in the same shipment.
