BENTLY 133396-01
Product introduction
The 133396-01 from Bently Nevada is a high-performance piezoelectric accelerometer sensor assembly designed as a critical vibration measurement component in 3500 Machinery Protection Systems. This rugged sensor directly measures dynamic acceleration and vibration in rotating and reciprocating machinery, converting mechanical motion into electrical signals that form the foundation of machinery health monitoring programs. Bently Nevada’s 133396-01 serves as the primary vibration detection device in countless industrial applications, capturing high-frequency vibration components that indicate early-stage bearing defects, gear wear, and structural resonance—data that, when processed by 140471-01 conditioning modules, enables both protection and predictive maintenance strategies.
Bently Nevada’s 133396-01 addresses the need for reliable high-frequency vibration measurement in harsh industrial environments. Its piezoelectric design provides exceptional sensitivity to subtle vibration patterns, while its rugged construction withstands extreme temperatures, mechanical shock, and environmental contaminants. When integrated with 140471-01 signal conditioning modules, this accelerometer delivers the high-quality vibration data that flows through 136188-01 input modules and 3500/34 gateways to operator displays and analytics platforms, forming the basis for informed machinery health decisions.
Core advantages and technical highlights
High-frequency measurement capability: The 133396-01 excels at capturing high-frequency vibration components up to 10 kHz, making it ideal for detecting early-stage faults in rolling element bearings, gear teeth, and high-speed rotating components. This high-frequency response complements the lower-frequency measurements from proximity sensors like the 128275-01-E, providing a complete vibration profile of machinery health.
Exceptional sensitivity and linearity: With a sensitivity of 100 mV/g and linear operation up to ±50 g peak, the accelerometer accurately measures both subtle vibration trends and severe transient events. This wide dynamic range ensures reliable detection of both incipient faults and catastrophic machinery events, supporting both predictive maintenance and protection functions.
Rugged environmental performance: Constructed with a 316L stainless steel housing and hermetically sealed design, the 133396-01 operates reliably in extreme temperatures from -55°C to +121°C. Its IP67 rating provides protection against dust ingress and temporary water immersion, making it suitable for installation in harsh environments including turbine enclosures, compressor skids, and outdoor equipment.
System-optimized connectivity: Equipped with a MIL-spec connector compatible with 163179-01 extension cables, the accelerometer integrates seamlessly into 3500 system architectures. This optimized connection ensures that high-frequency vibration signals reach 140471-01 conditioning modules with minimal signal loss or noise interference, preserving the diagnostic value of the original measurements.
Typical application scenarios
In power generation facilities, the 133396-01 is installed on turbine and generator bearing housings to monitor high-frequency vibration associated with bearing condition and rotor dynamics. Mounted in conjunction with 128275-01-E proximity sensors, it provides complementary vibration data that helps distinguish between shaft-related and structure-related vibration issues. Signals from these accelerometers are conditioned by 140471-01 modules, with processed data transmitted via 3500/34 gateways to both protection systems and diagnostic platforms for detailed spectral analysis.
Oil and gas processing plants utilize the 133396-01 on pump and motor bearing housings, where its rugged design withstands the harsh conditions of processing environments. The accelerometer’s high-frequency response detects early-stage bearing defects in critical pumps, providing advance warning that enables maintenance before unplanned failures occur. Conditioned signals from 140471-01 modules help operators distinguish between normal operational vibration and potential mechanical issues requiring intervention.
Manufacturing facilities deploy the 133396-01 on production line machinery such as gearboxes, fans, and conveyors, where its sensitivity to high-frequency vibration enables detection of gear mesh problems, belt defects, and motor bearing degradation. Installed in production-critical equipment, these accelerometers provide continuous vibration data that is processed by 136188-01 modules and displayed on 3500/60 systems, helping maintenance teams schedule repairs during planned downtime to maximize production efficiency.

Installation, calibration and maintenance instructions
Installation preparation: Before installing the 133396-01, verify the mounting location provides a rigid connection to the machinery structure (avoid flexible surfaces). Ensure the measurement axis aligns with the direction of interest (typically vertical or horizontal vibration). Required tools include a torque wrench, mounting hardware (10-32 UNF stud), and cable management accessories. Inspect the sensor and cable for damage, particularly checking the connector pins and cable jacket.
Mounting procedure: Secure the 133396-01 using the 10-32 UNF mounting stud, torquing to 2.3 Nm (20 in-lbs) to ensure proper mechanical coupling. For temporary installations, use approved adhesive mounting pads. Position the sensor to minimize cable strain, avoiding sharp bends or contact with rotating components. Connect the sensor to the conditioning system using 163179-01 extension cables, ensuring proper alignment of the MIL-C-5015 connector before mating.
Calibration process: After installation, verify sensor performance using the 330130-080-00-00 calibration fixture or a shaker table. Check sensitivity at reference frequencies (typically 100 Hz and 1 kHz) to confirm it remains within the ±5% specification. For critical applications, perform a full frequency response check from 0.5 Hz to 10 kHz. Document calibration results and store with system records, repeating calibration annually or after sensor removal/reinstallation.
Maintenance suggestions: Include the 133396-01 in quarterly visual inspections, checking for loose mounting hardware, cable damage, and contamination on the sensor housing. Ensure cable connectors remain secure and free from corrosion. During scheduled shutdowns, verify mounting torque and inspect the mounting surface for corrosion or damage. If vibration data appears 异常,check for loose connections or mounting issues before suspecting sensor failure. Clean the sensor housing with a soft cloth—avoid using solvents that could damage the housing or cable jacket.
