Function

Sensor signal interface: Processes input signals from proximity probes, seismic sensors, velocity sensors and accelerometers, and performs signal conditioning to generate vibration, velocity, acceleration and position data.

Data output: Provides 4-20mA analog output (proportional to the measured value) and digital signals, supporting Modbus and Bently Nevada proprietary protocols for data transmission and system integration.

Alarm and Protection: Supports user-configurable alarm and danger thresholds, triggers relay output (such as OK, alarm, dangerous status), and protects equipment from vibration or abnormal position.

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

Internal terminal design: Directly connect the sensor through the internal terminal, simplifying installation and reducing the need for external wiring.

Status indication: In coordination with the main module, it provides LED indications (OK, TX/RX, Bypass), facilitating 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, vibration data is transmitted via 4-20mA output or digital protocols, supporting 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.
