03 · INSTALLATION

Surface preparation controls the result

Choose location

Select a rigid bearing housing or casing point that transmits the vibration of interest.

Prepare mounting

Use the M8 × 1 interface, maintain a flat clean surface and tighten to 4.1 N·m.

Check signal

Confirm −24 Vdc excitation, bias voltage, cable continuity and channel scaling before service.

System relationship: The three-wire sensor needs external −24 Vdc excitation and a compatible acceleration input channel. Maximum cable length is 305 m without signal degradation.

05 · BUYER FAQ

Details that change measurement quality

Ⓠ Why choose 330425-02-05 instead of 330400-02-05?

Ⓐ The 330425 supports 75 g peak and 25 mV/g, making it better suited to higher acceleration levels; the 330400 offers 100 mV/g and a 50 g range.

Ⓠ Can 330425-02-05 be mounted in any orientation?

Ⓐ Yes, but the sensing axis, mounting rigidity, surface finish and 4.1 N·m torque still determine measurement quality.

Ⓠ What does the bias voltage reveal on 330425-02-05?

Ⓐ A normal bias near −8.5 Vdc indicates a powered sensor and intact circuit; a major shift can indicate wiring, excitation or sensor trouble.

Ⓠ Why can base strain affect 330425-02-05 readings?

Ⓐ Distortion at the mounting surface can couple into the piezoelectric element. A flat rigid mounting point and the correct base arrangement reduce this effect.

Ⓠ Is 330425-02-05 suitable for low-speed unbalance monitoring?

Ⓐ Its specified span begins at 10 Hz. For slower phenomena, confirm that the expected vibration frequency remains within the useful response of the complete measurement chain.
