Product Overview

The Bently Nevada 3500/50-01-00-01 133442-01 is a dual-channel tachometer module designed for precision monitoring of rotating machinery. As part of the 3500 Series platform, this module integrates seamlessly with Bently Nevada’s machinery protection systems to deliver real-time insights into shaft rotational speed, acceleration, direction, and peak speed events. Unlike standalone tachometers, the 133442-01 combines signal conditioning, internal terminations, and advanced diagnostic capabilities, acting as a centralized hub for speed-related data processing .

Key to its value is the peak hold function, which stores the highest speed, reverse speed, and number of reverse rotations for post-fault analysis. Its modular design allows easy integration into existing 3500 Series racks, supporting applications in oil and gas, power generation, and manufacturing. Compliance with API 670 standards ensures reliability in safety-critical environments, while dual 4–20 mA outputs per channel facilitate seamless integration with distributed control systems (DCS) .

Main Features and Advantages

Multi-Function Monitoring:
The 133442-01 supports simultaneous measurement of rotational speed, rotor acceleration, and direction. Its peak hold function captures transient events (e.g., overspeed during startup) for post-fault analysis, eliminating the need for external data loggers. This is particularly valuable in applications like gas turbines, where rapid speed fluctuations must be analyzed retrospectively .

Keyphasor Signal Integration:
Unique to the 133442-01, it provides conditioned keyphasor signals directly to the 3500 rack backplane, eliminating the need for a separate keyphasor module. This simplifies system architecture and reduces cabling complexity, making it ideal for retrofitting legacy systems or building compact monitoring solutions .

Modular Design with Internal Terminations:
By integrating termination blocks within the module, the 133442-01 reduces cabling complexity and minimizes EMI interference. This design is particularly beneficial in harsh environments (e.g., offshore platforms) where external connections are vulnerable to corrosion. The internal terminations also support quick sensor changes without rewiring the entire system .

Wide-Range Compatibility:
Supports proximity probes (e.g., 3300 XL series) and magnetic pickups, making it suitable for legacy and modern machinery. The dual 4–20 mA outputs allow integration with SCADA systems for centralized data management. Unlike the 288062-02 model, the 133442-01 explicitly supports Modbus TCP/IP, enabling direct integration with modern industrial IoT platforms .

Rugged Construction:
Built to withstand extreme conditions, the module features an IP65-rated enclosure and shock-resistant design. Front-panel LEDs provide real-time status updates (OK, TX/RX, bypass mode), simplifying troubleshooting. Its operating temperature range (-40°C to +85°C) ensures stability in both arctic and desert environments .

Application Areas

The Bently Nevada 3500/50-01-00-01 133442-01 excels in industries where precise speed monitoring is critical:

Oil and Gas: Monitoring compressors and pumps to prevent overspeed failures. Its peak hold function aids in analyzing surge events during process upsets. The keyphasor support is particularly useful for turbine blade vibration analysis .
Power Generation: Safeguarding steam turbines by detecting rotational anomalies. The module’s API 670 compliance meets stringent power plant safety requirements. Its Modbus TCP/IP support enables seamless integration with smart grid systems .
Manufacturing: Optimizing conveyor systems and high-speed rollers in automotive and pulp mills. The adjustable filtering ensures reliable data in noisy environments .
Mining: Ensuring continuous operation of crushers and slurry pumps. The wide temperature range (-40°C to +85°C) makes it suitable for harsh outdoor conditions .
