BENTLY 128240-01

Product introduction

The 128240-01 from Bently Nevada is a precision calibration verification tool, engineered to ensure the accuracy and reliability of vibration sensors and transmitters in industrial monitoring systems. As a critical maintenance accessory in Bently Nevada’s ecosystem, this portable device provides on-site verification of sensor performance, ensuring that vibration measurement data remains trustworthy for machinery health assessment and protection.

Designed for ease of use in industrial environments, the 128240-01 verifies the performance of velocity sensors, accelerometers, and transmitters—including popular models like the 330104-00-05-10-02-CN and 22810-01-05-50-02. Its compact, battery-powered design allows technicians to perform calibration checks at the sensor installation point, eliminating the need for costly removal and laboratory testing. When used regularly as part of maintenance programs, this verification tool ensures measurement integrity, reduces false alarms, and supports confident decision-making based on vibration data.

Core advantages and technical highlights

Precision measurement capability: The 128240-01 delivers laboratory-grade accuracy (±1% of reading) in a portable format, ensuring reliable verification of vibration sensors across their operating range. Its wide measurement spectrum (0.1-50mm/s velocity and 0.01-10g acceleration) covers the performance range of most industrial vibration sensors, while the 1Hz-10kHz frequency range verifies sensor response across critical machinery vibration frequencies. This precision ensures that even subtle calibration drift is detected before it affects monitoring accuracy.

On-site verification convenience: Unlike traditional calibration methods requiring sensor removal, the 128240-01 enables verification at the installation point using its magnetic mounting base. This capability eliminates downtime associated with sensor removal and reinstallation, particularly valuable for critical machinery where unplanned shutdowns are costly. Technicians can quickly verify sensor performance during routine maintenance outages, ensuring continuous measurement reliability.

Intuitive operation: The tool features a user-friendly interface with clear digital display and simple navigation menus, allowing technicians to perform verification tests without specialized training. Pre-programmed test routines for common Bently Nevada sensors simplify operation, while customizable parameters accommodate special verification requirements. Results are displayed instantly, with pass/fail indicators for quick assessment of sensor performance.

Flexible connectivity: Equipped with USB, Bluetooth, and analog output options, the 128240-01 offers versatile data capture and documentation capabilities. Test results can be stored on the device, transferred to mobile devices via Bluetooth, or downloaded to computers via USB for record-keeping and trend analysis. This connectivity supports compliance with quality standards and maintenance documentation requirements.

Long-lasting portability: The rechargeable lithium-ion battery provides 12 hours of continuous operation, enabling full-shift use without recharging. The rugged housing withstands drops up to 1m and resists dust and moisture (IP54 rating), ensuring durability in industrial environments. Its compact size and lightweight design (0.5kg) make it easy to carry between measurement points throughout a facility.

Typical application scenarios

In power generation plants, the 128240-01 is used during annual maintenance outages to verify the calibration of 330104-00-05-10-02-CN velocity sensors mounted on turbine bearing housings using 106M1081-01 adapters. Technicians attach the tool’s magnetic base to the sensor mounting surface, generate known vibration levels, and compare sensor output to the tool’s reference measurement. This process ensures that critical turbine vibration data remains accurate for both protection and condition monitoring purposes.

Within petrochemical facilities, the verification tool is deployed quarterly to check accelerometers and transmitters monitoring compressor trains. Its portability allows use in hazardous areas (when properly certified) to verify sensor performance in situ, ensuring that vibration measurements used for predictive maintenance remain reliable. The tool’s data logging capability documents sensor performance over time, supporting trending analysis of calibration stability.

In manufacturing facilities, the 128240-01 provides routine verification of vibration sensors on production line machinery, including motors, pumps, and gearboxes. Maintenance teams use the tool to confirm sensor accuracy after machinery overhauls or sensor replacement, ensuring consistent measurement across identical equipment. This consistency enables meaningful comparison of vibration data between similar machines, improving diagnostic accuracy and maintenance planning.

Operation and maintenance instructions

Preparation for verification: Before using the 128240-01, ensure the tool is fully charged and calibrated (per manufacturer recommendations, annually). Select the appropriate test routine based on the sensor type (velocity, acceleration, or transmitter). Inspect the magnetic base for debris that could affect coupling to the mounting surface. For sensors mounted with 106M1081-01 adapters, ensure the mounting surface is clean and flat for proper tool attachment.

Verification procedure: Attach the 128240-01 to the sensor mounting surface using its magnetic base, positioning it as close as possible to the sensor without mechanical interference. Connect the tool to the monitoring system or directly to the sensor output using appropriate cables. Select the desired frequency and amplitude, then initiate the vibration test. Record the sensor output and compare to the tool’s reference value, documenting any deviation beyond acceptable limits (typically ±5% for in-service verification).

Data documentation: Store verification results on the device, including timestamp, sensor ID, location, frequency, amplitude, and measured deviation. Transfer results to maintenance systems via USB or Bluetooth for long-term record-keeping. Generate calibration certificates for compliance documentation when required. Establish a trending database to monitor sensor stability over time, scheduling full recalibration when drift patterns exceed thresholds.

Tool maintenance: Keep the magnetic base clean and free of debris to ensure proper vibration transfer during tests. Charge the battery fully before each use and perform monthly battery health checks to maintain capacity. Store the tool in its protective case when not in use, avoiding extreme temperatures and physical damage. Send the tool to an authorized service center annually for calibration verification to maintain its NIST-traceable accuracy.
