Function

Signal conditioning and measurement: Process input signals from proximity probes, seismic sensors, velocity sensors, and accelerometers, generate static values such as vibration, velocity, acceleration, and position (such as direct values, gaps, 1X amplitude/phase), and support multiple filtering options (integration, bandpass, 1X tracking).

Alarm and Protection: Continuously compare monitoring parameters with user-configurable alarm/danger thresholds, trigger relay output (OK, alarm, danger), and protect machinery from vibration or abnormal position.

Data output: Provides 4-20mA analog output and digital signals, supports Modbus and Bently Nevada proprietary protocols, and integrates with DCS/SCADA systems.

Channel isolation: 4 channels are processed independently to ensure data accuracy and fault isolation. It supports TMR mode to enhance system reliability.

Configuration and Diagnosis: Adjust the range, filtering and measurement type through the 3500 rack configuration software; Equipped with LED indicators (OK, TX/RX, Bypass) for on-site diagnosis.

Application scenarios

Rotating machinery monitoring: Used in turbines, compressors, pumps and motors in petrochemicals, power plants and manufacturing industries, it monitors vibration, speed and position to detect faults such as imbalance, bearing wear or misalignment.

Predictive maintenance: Through real-time data collection and trend analysis, potential problems are identified, maintenance plans are optimized, and unexpected downtime is reduced.

Industrial automation integration: Integrated with DCS/SCADA systems, it transmits vibration data through analog/digital output and supports remote monitoring and alarm.

Critical equipment protection: Provide continuous vibration monitoring and protection in high-risk environments (such as natural gas processing plants, offshore platforms) to ensure equipment safety and operational continuity.
