BENTLY 167699-02

Product introduction

The 167699-02 from Bently Nevada is a precision signal conditioner module, engineered to process and amplify signals from industrial vibration sensors in machinery health monitoring systems. As a key component in Bently Nevada’s signal processing ecosystem, the 167699-02 bridges the gap between raw sensor data and monitoring/control systems, ensuring accurate, reliable measurements in demanding industrial environments.

Designed to work seamlessly with Bently Nevada’s velocity sensors like the 330106-05-30-10-02-CN and accelerometers, the 167699-02 conditions analog signals to eliminate noise and interference, delivering clean data to PLCs, DCS, or dedicated machinery protection systems. Its compact design and flexible mounting options make the 167699-02 suitable for both new installations and system upgrades, providing critical signal conditioning that enhances the performance of vibration monitoring systems in power generation, manufacturing, and oil and gas applications.

Core advantages and technical highlights

Superior signal conditioning: The 167699-02 features advanced filtering and amplification circuitry that improves signal-to-noise ratio by up to 40dB, ensuring accurate measurement of subtle vibration patterns that indicate early machinery issues. Its ±0.1% accuracy ensures that critical vibration data—such as bearing wear signatures or rotor imbalance—remains precise, even in electrically noisy industrial environments.

Enhanced isolation protection: With a 2.5kVrms isolation rating, the 167699-02 protects sensitive monitoring equipment from ground loops and voltage transients common in industrial settings. This isolation prevents signal corruption and equipment damage caused by electrical interference, making it ideal for installations near high-voltage motors, variable frequency drives, or power distribution systems.

Flexible integration: The 167699-02 offers multiple output options (4-20mA, 0-10V, and Modbus RTU) that simplify integration with virtually any industrial control or monitoring system. Its DIN rail mounting design allows for quick installation in control cabinets, while the wide operating temperature range (-40°C to 70°C) ensures reliable performance in both hot and cold environments, from desert refineries to arctic processing facilities.

Typical application scenarios

In coal-fired power plants, the 167699-02 is installed in control cabinets to condition signals from vibration sensors on boiler feed pumps and induced draft fans. By filtering out electrical noise from nearby motors and generators, it ensures accurate measurement of pump bearing vibration, enabling early detection of impeller imbalance or seal wear. This helps plant operators schedule maintenance during planned outages, avoiding costly unplanned shutdowns of critical power generation equipment.

Within automotive manufacturing plants, the 167699-02 processes signals from accelerometers on production line robots and conveyor motors. Its fast response time (<10ms) captures rapid vibration changes that indicate gearbox degradation or drive belt slippage, triggering alerts before mechanical failures disrupt assembly lines. The module’s compact size allows installation in space-constrained control panels, maintaining clean signal paths in electrically dense factory environments.

In offshore oil platforms, the 167699-02 conditions vibration data from subsea pump sensors and topside compressors. Its wide temperature tolerance and robust construction withstand the harsh marine environment, while the isolation protection prevents signal interference from platform electrical systems. By ensuring reliable vibration measurements, the 167699-02 helps maintain continuous oil production and prevents equipment failures in remote locations where repair is costly and time-consuming.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 167699-02, ensure the DIN rail is properly mounted in a clean, dry control cabinet with adequate ventilation. Verify that the 24V DC power supply is stable and properly grounded to prevent voltage spikes. Use shielded twisted-pair cables to connect sensors to the 167699-02, grounding the shield at both ends to maximize noise rejection. Leave at least 50mm of space around the module for airflow, and avoid mounting near heat sources or high-voltage components.

Maintenance suggestions: Inspect the 167699-02 semi-annually for loose connections or signs of overheating (discoloration or burning smells). Clean dust from the module using compressed air to maintain cooling efficiency. Calibrate the module annually using a signal generator and precision meter to verify accuracy—this is critical for ensuring vibration measurements remain reliable over time. If communication issues occur, check Modbus wiring and termination resistors; for analog output problems, verify power supply stability and load impedance matches specifications.
