Bently Nevada 3500/64M 176449-05 Four-Channel Dynamic Pressure Monitoring Module

Function Features

• Multi-channel Isolated Measurement: It is equipped with four isolated channels that can independently collect and process dynamic pressure signals. This isolation design prevents signal interference between channels and ensures the accuracy of measurements even when multiple pressure points are monitored simultaneously.
• Precise Filtering Capabilities: It adopts advanced bandpass filtering and notch filtering technologies. These technologies can isolate pressure fluctuations within specific frequency ranges, which is critical for identifying problems such as pump cavitation and turbine aerodynamic instability through narrowband pressure spikes.
• Configurable Alarm Mechanisms: Users can set alert and danger setpoints for each measured variable based on equipment operating requirements. When the dynamic pressure exceeds the set thresholds, the module promptly triggers alarms to avoid catastrophic equipment failures.
• Seamless System Integration: It communicates with other modules in the 3500 series like communication gateways and power supply modules via the chassis backplane. It can also provide Keyphasor signals to coordinate with vibration and temperature monitoring modules, achieving comprehensive machinery health monitoring.
• Rugged Environmental Adaptability: Its IP67 rating effectively prevents dust and water ingress. It can resist vibration and electromagnetic interference, and its wide operating temperature range enables stable operation in extreme climate conditions and harsh industrial environments such as offshore platforms and petrochemical plants.
• Recorder Output Function: It is furnished with recorder outputs that can transmit real-time dynamic pressure data to external control systems. This facilitates continuous data recording and post-event analysis, laying a foundation for equipment performance optimization and maintenance plan formulation.
