The S3960 444-680-000-511 is a high-performance, all-purpose piezoelectric vibration sensor (accelerometer) from Vibro-Meter / Meggitt for use with heavy machinery in harsh industrial environments. It utilizes the industry-standard 2-wire voltage transmission technique with a constant current supply, delivering a factory-calibrated sensitivity of 100 mV/g. Thanks to the accelerometer's isolated ground and internal shield, no ground loops or frame voltages are present to disturb the high-precision measurement.
Hermetically sealed for harsh environments
Shear mode operation, therefore no output due to thermal transients
Designed for medium temperature industrial applications (-50°C to +120°C)
The sensor demonstrates extremely low noise levels and exceptional bias voltage stability at elevated temperatures ranging from -55°C to +120°C. Structurally, it features a shear-mode crystal geometry that eliminates false signal outputs caused by thermal transients. Enclosed in a premium stainless steel housing with a complete hermetic welding seal, it maintains total operational integrity against moisture, dust, and chemical splashes. The device provides a flat frequency response from 3 Hz to 5 kHz (±5%), backed by a high mounted resonant frequency exceeding 30 kHz to ensure precise vibration data extraction from rotating machinery. Its integrated electronics allow direct attachment to the surfaces of motors, fans, pumps, and gearboxes via standard 1/4-28 UNF mounting studs, offering a low-impedance voltage output that prevents ambient noise injection over long cabling runs.

During the use of the S3960 444-680-000-511 signal conditioning module, it is vital to ensure proper rack insertion and secure mounting within the VM600 chassis to prevent intermittent backplane connections. Always verify that the input voltage complies with the stable 24 VDC specifications to avoid hardware damage from voltage fluctuations.
Carefully configure and calibrate the scaling parameters for the eight channels using the VM600 MPS software prior to system commissioning. Maintain strict isolation of the 4-20 mA loop wiring to eliminate electrical noise interference and preserve the ±0.1% measurement accuracy. Avoid hot-swapping the card while the machinery protection system is active to prevent false trips or data loss in the connected plant control architecture.
The S3960 444-680-000-511 (CE 680 M511) is an industrial IEPE piezoelectric accelerometer for harsh environments. Driven by a two-wire constant current supply, it outputs a 100 mV/g dynamic voltage signal proportional to acceleration. An isolated ground and internal shield eliminate ground-loop interference, while the low 100-ohm output impedance permits long-distance cabling to route vibration data directly into PLCs, DCSs, or downstream monitoring racks.

It is a general-purpose vibration sensor with integrated electronics (IEPE) for machinery vibration monitoring in harsh industrial environments.
What signal transmission technique does the S3960 444-680-000-511 utilize?
It utilizes the industry-standard 2-wire voltage transmission technique with a constant current supply for both powering and signal routing.
How does the S3960 444-680-000-511 prevent industrial ground loop interference?
It prevents measurement disturbances from frame voltages or ground loops via an isolated ground and an internal shield.
What material is used for the housing of the S3960 444-680-000-511?
It features a rugged stainless steel housing with a complete hermetic welding seal to counter moisture and dust.
How should the S3960 444-680-000-511 sensor be properly mounted?
Secure it tightly to a rigid, flat surface of the machinery using a standard 1/4-28 UNF mounting stud.
