AskA 100 mV/g, three-wire piezoelectric accelerometer for machinery-casing acceleration measurements.
330400-02-CN belongs to the 330400 accelerometer family used for machinery-casing acceleration measurements. The 02 mounting option specifies an integral M8 × 1 stud.
The transducer uses a three-wire, -24 Vdc configuration and provides a nominal 100 mV/g sensitivity with a 10 Hz to 15 kHz amplitude response.
Installation quality depends on a flat, rigid mounting surface, correct stud engagement and a documented cable and monitor-input path.
The integral M8 × 1 stud must match the prepared machine surface.
Confirm the three-wire -24 Vdc monitor input and field wiring.
Review mounting resonance and the application band before comparing measurements.

Yes. The 330400 is intended for critical casing-acceleration measurements, including gear-mesh monitoring, when vibration is transmitted effectively to the mounting point.
Its integral stud is M8 × 1, so a 1/4-28 mounting point is not the same mechanical interface and needs the correct mounting solution.
Use a compatible three-wire input that provides -24 ±0.5 Vdc and supports the sensor’s 100 mV/g signal.
A compliant sensor can still under-report casing vibration when the mounting surface, stud torque or machine location does not transmit vibration effectively.
The sensor body is equivalent to IP68, but the cable is excluded; the connector and wiring need installation-specific protection.
Include the M8 × 1 mounting point, cable length and termination, monitor input, temperature range and a clear nameplate image.
Share the exact nameplate, mounting or route dimensions, connected component labels and approval documents. ApterPLC can then prepare a model-focused quotation without treating a similar connector or family name as proof of interchangeability.
ApterPLC provides a one-year warranty on this item, giving buyers a clear support path after delivery.
