Product Name
3500/42M 140734-02 Machinery Protection Module
Product Description
The 3500/42M 140734-02 module is a high-performance machinery protection module designed for Bently Nevada 3500 monitoring systems, specializing in continuous vibration and position monitoring of rotating equipment such as turbines, compressors, and pumps. It collects real-time data from proximity probes, accelerometers, and velocity transducers, processes the signals to detect anomalies (e.g., imbalance, misalignment, or bearing wear), and triggers alarms or shutdowns to prevent catastrophic equipment failure.
In a natural gas pipeline compressor station, this module monitors 8 radial vibration sensors and 4 axial position sensors on a 5MW compressor. It samples data at 1024Hz per channel, analyzing vibration amplitudes with a resolution of 0.1µm, and detects early-stage bearing degradation (vibration increase of 2µm RMS) 2 weeks before critical failure, allowing scheduled maintenance and avoiding unplanned downtime costing $50,000 per hour. In a power plant’s steam turbine system, it processes signals from 6 vibration sensors, comparing real-time data to predefined thresholds and transmitting alerts to the control room within 10ms of exceeding limits, ensuring turbine operation within safe parameters and extending service life by 3 years.
Constructed with rugged industrial-grade components, the module operates reliably in harsh environments with temperatures ranging from -30°C to 70°C, high vibration, and electromagnetic interference. It integrates seamlessly with the 3500 rack system, supporting hot swapping for minimal maintenance downtime. This module is widely used in oil and gas, power generation, chemical processing, and marine industries where continuous machinery health monitoring is critical for operational safety and cost efficiency.
