Product System Overview
The Bently Nevada 3500/50 133388-02 is a professional dual-channel tachometer and overspeed monitoring module designed for the industry-leading 3500 machinery protection system by Baker Hughes. As a dedicated speed monitoring core component of the TSI turbine supervision instrumentation system, it complements vibration, displacement and temperature monitoring modules to form a complete API 670-compliant full-dimensional machinery safety protection solution. This module focuses on rotational speed detection, overspeed protection and rotation direction judgment, filling the core monitoring gap of mechanical speed anomalies that conventional monitoring cards cannot cover. It seamlessly matches the standard 3500 rack architecture, supporting stable data interaction with System 1 diagnostic software, DCS and SCADA industrial control platforms. Widely verified in global energy and process industries, it serves as a standard configuration for new system construction, equipment upgrade and faulty module replacement of high-value rotating machinery monitoring systems.

Core Product Functions
This high-performance tachometer module undertakes high-precision speed collection, real-time judgment and safety protection tasks for industrial rotating equipment. Equipped with two fully independent signal channels, it stably receives and processes pulse signals from eddy current probes and magnetic speed sensors, achieving accurate real-time measurement of equipment rotational speed within 0–20000 RPM. It supports intelligent identification of forward and reverse rotation status, effectively judging abnormal rotation faults of mechanical equipment. Users can flexibly configure overspeed alarm and trip threshold parameters through official 3500 configuration software. Once the equipment speed exceeds the preset safe range, the module will instantly trigger hierarchical alarm signals and safety interlock actions to prevent equipment overspeed runaway and mechanical damage. In addition, it integrates peak speed hold and reverse rotation counting functions, continuously recording speed change trends and abnormal operation data, providing accurate data support for equipment fault tracing and predictive maintenance.

Product Features & Technical Advantages
The 3500/50 133388-02 module features ultra-high measurement precision, powerful comprehensive functions and excellent industrial environmental adaptability, meeting strict safety monitoring standards for core industrial equipment. Adopting optimized high-resolution signal processing algorithm, it delivers measurement accuracy up to ±0.1% and 0.1 RPM resolution, capturing subtle speed fluctuations that affect equipment operation safety. The dual-channel independent design avoids signal cross-interference, supporting redundant monitoring configuration to further improve system reliability. Built-in multi-level signal filtering mechanism effectively eliminates on-site electromagnetic clutter and pulse interference, ensuring stable and true speed data output in harsh factory environments. It integrates self-diagnosis function to automatically detect sensor faults, signal disconnection and module anomalies, reducing monitoring blind spots and false alarms. The standardized rack-mounted plug-and-play structure simplifies on-site installation and replacement procedures, greatly shortening maintenance downtime and reducing overall system operation and maintenance costs.
