BENTLY 3500/44-01-00

Product introduction

The Bently Nevada 3500/44-01-00 is a 4-channel dynamic signal monitoring module, designed to capture and process high-fidelity vibration and position signals from rotating machinery. As a key component in mid-range monitoring systems, it bridges the gap between basic vibration monitors and advanced analyzers, offering reliable dynamic signal processing for applications that require more detailed insights than entry-level modules but don’t need the full capabilities of high-end analyzers like the 3500/44M-01-00 176449-03.

This module is engineered to work seamlessly with controllers such as the 3500/53 133388-01, providing processed dynamic data for alarm triggering and machinery health assessment. It accepts inputs from a variety of sensors—including proximity probes for shaft position monitoring and accelerometers for bearing vibration measurement—making it versatile across different machinery types, from pumps and fans to medium-sized turbines.

Powered by stable supplies like the 3500/91 190782-01, the 3500/44-01-00 delivers consistent performance in harsh industrial environments, ensuring accurate signal capture even in conditions with temperature extremes or electrical noise. Its integration with the 3500/53 133388-01 controller allows for centralized monitoring and control, making it a cost-effective choice for mid-scale industrial facilities.

Core advantages and technical highlights

Balanced performance and cost: The 3500/44-01-00 strikes a practical balance between functionality and affordability. With a 16-bit ADC and 25.6 kHz sampling rate, it captures sufficient detail for most mid-range monitoring needs—such as detecting bearing faults or rotor imbalance—without the higher cost of 24-bit systems. This makes it ideal for facilities with moderate monitoring requirements, like food processing plants or wastewater treatment facilities using the 3500/53 133388-01 controller.

Multi-sensor compatibility: Supporting proximity probes, accelerometers, and velocity transducers, the module adapts to diverse machinery monitoring needs. For example, it can simultaneously process shaft position data from proximity probes on a pump and bearing vibration from accelerometers on a motor, providing a comprehensive view of machinery health to the 3500/53 133388-01 controller.

Integrated FFT analysis: Equipped with built-in FFT analysis (up to 8192 points), the 3500/44-01-00 identifies frequency components in vibration signals—critical for diagnosing issues like gear mesh problems or misalignment. This processed frequency data is transmitted to the 3500/53 133388-01, enabling the controller to trigger targeted alarms based on specific frequency patterns, reducing false positives.

Seamless system integration: The module communicates seamlessly with the 3500/53 133388-01 controller via the backplane, ensuring processed data is efficiently used for alarm logic and protective actions via the 3500/60. Its compatibility with 170180-01-00 software allows for easy configuration of sampling rates, frequency ranges, and sensor types, simplifying setup and maintenance.

Typical application scenarios

In a municipal wastewater treatment plant, the 3500/44-01-00 is paired with the 3500/53 133388-01 controller to monitor 4 large submersible pumps. Each channel connects to a combination of proximity probes (measuring shaft position) and accelerometers (monitoring bearing vibration). The module’s FFT analysis detects increasing 1x frequency vibration in one pump, indicating rotor imbalance, which the 3500/53 133388-01 uses to trigger a warning via the 3500/60, allowing maintenance to be scheduled during off-peak hours.

At a food and beverage production facility, the module monitors 2 conveyor belt motors and 2 mixers, integrated with the 3500/53 133388-01. It processes vibration data from accelerometers, using FFT to identify characteristic frequencies of bearing wear in one mixer. The controller uses this data to activate a maintenance alert, preventing unexpected downtime during production runs. The 3500/91 190782-01 ensures uninterrupted power, even during plant voltage fluctuations.

In a small-scale power generation plant, the 3500/44-01-00 monitors auxiliary systems (cooling pumps, fans) alongside a 3500/53 133388-01 controller. It captures vibration data from velocity transducers on pump bearings, processing signals to detect early signs of lubrication failure. The controller triggers the 3500/60 to shut down the pump before catastrophic failure, while logging the event for later analysis via 170180-01-00 software.
