Meggitt S3960-144-159-000-501 Vibration Transducer Unit

Module Feature

S3960-144-159-000-501 is a piezoelectric vibration accelerometer from Meggitt S3960 series.

It is designed for continuous vibration measurement of turbines, pumps, fans and other rotating machinery. It outputs charge signal proportional to vibration acceleration. The rugged sealed housing adapts to high temperature and harsh industrial environments. Widely stocked as spare part for power plant and petrochemical online condition monitoring system.

Working principle

Internal piezoelectric crystal generates electric charge under mechanical vibration acceleration.

The charge signal is transmitted to the signal conditioner or monitoring module through dedicated low-noise cable. The system converts charge signal into vibration value, used for vibration trend tracking, alarm and fault diagnosis of rotating equipment.

Onboard components

Piezoelectric sensing crystal, internal insulator, hermetically sealed metal housing, integral cable connector and shielding structure.

LED indicators

No built-in LED indicator.

Hardware self‑diagnosis

Check cable insulation, connector tightness and signal integrity by monitoring system. No local adjustment.

Programming software

Not applicable, raw charge output transducer, matched with vibration monitoring system software.
