Overview
The Bently Nevada 177988-01 Prox Accel Seismic (PAS) Module is part of the ADAPT 3701/40 Machinery Dynamics Monitor series, designed for high-performance vibration and position monitoring of critical rotating equipment such as turbines, compressors, and gearboxes. It supports simultaneous processing of proximity probes, accelerometers, and seismic sensors, enabling comprehensive diagnostics including radial vibration, thrust position, and casing vibration.
Its DSP-based real-time analysis ensures fast response to abnormal machinery behavior, improving reliability and reducing unplanned shutdowns. The module also supports multi-event Keyphasor® inputs and dynamic pressure measurements, making it ideal for machines with complex dynamic characteristics.
In harsh industrial environments like petrochemical facilities, the 177988-01 helps detect bearing wear, imbalance, misalignment, and casing vibration issues before they escalate — enabling predictive maintenance and asset health optimization.
