Introduction
3500/25 149369-01 is a high-precision industrial single-channel dedicated monitoring module designed for targeted tracking of critical parameters in heavy-duty rotating machinery and key industrial equipment. As a specialized component of the 3500-series monitoring platform, it integrates high-sensitivity sensing technology, low-noise signal processing circuits, and a compact, rugged industrial-grade housing—enabling real-time, accurate capture of single-core parameters (e.g., high-precision vibration, shaft displacement, or bearing temperature) while maintaining stable performance in harsh operating environments. Its streamlined design prioritizes reliability and ease of integration, with seamless compatibility for 3500-series racks and standard industrial sensors, ensuring rapid deployment in space-constrained or focused monitoring scenarios. The module features robust environmental resistance, including protection against extreme temperatures, electromagnetic interference, and dust, making it an ideal solution for early fault detection, predictive maintenance, and operational safety assurance of high-value industrial equipment across energy, petrochemical, manufacturing, and marine sectors.

Application Scenarios
  1. Power Plant Turbine Bearing Vibration Monitoring: Installed in gas, steam, and hydroelectric turbine bearing systems to focus on radial/axial vibration of critical bearings. Its high measurement accuracy captures subtle vibration anomalies caused by bearing inner/outer race wear, lubrication degradation, or rotor misalignment—providing early alerts to maintenance teams. By integrating with the turbine’s control system via the 3500 backplane, it prevents catastrophic bearing failures that could lead to prolonged power outages and high repair costs.

  1. Petrochemical Centrifugal Pump Shaft Displacement Tracking: Integrated into centrifugal pumps in oil refineries and chemical plants to monitor pump shaft axial displacement. The module’s IP67 protection and IECEx certification enable deployment in Zone 2 hazardous areas (e.g., near hydrocarbon fluid lines), withstanding high-pressure, corrosive environments. It detects shaft displacement deviations caused by impeller cavitation or mechanical seal wear, ensuring continuous fluid transfer and avoiding process interruptions due to pump breakdowns.

  1. Marine Auxiliary Generator Bearing Temperature Monitoring: Applied in marine auxiliary generator bearing systems to track real-time bearing temperature. Its corrosion-resistant aluminum alloy housing resists saltwater humidity and marine vibration, while the low-noise signal processing ensures accurate temperature readings even in noisy electrical environments. By triggering over-temperature alarms, it prevents generator bearing burnout, ensuring reliable power supply for ship systems (e.g., navigation, lighting) during long sea voyages.

  1. Steel Mill Rolling Mill Work Roll Vibration Monitoring: Utilized in hot rolling and cold rolling mill work rolls to monitor radial vibration. It adapts to high temperatures (up to 125°C) and metal dust, capturing vibration spikes caused by roll wear, thermal stress, or uneven ore feeding. By transmitting real-time vibration data to the mill’s PLC via Modbus RTU, it enables dynamic adjustment of rolling speed—maintaining consistent steel plate/coil quality and reducing roll replacement frequency.

  1. Mining Conveyor Drive Pulley Displacement Monitoring: Mounted on mining conveyor belt drive pulleys to monitor pulley radial displacement. Its shock resistance (45 G peak) withstands high-impact mining environments, while the dust-proof design prevents particle ingress. It detects displacement anomalies caused by pulley misalignment, bearing damage, or belt tension imbalance—triggering timely maintenance to avoid conveyor shutdowns and ensure continuous ore transportation.

  1. Aerospace Ground Test Component Vibration Sensing: Installed in aircraft engine accessory test benches (e.g., hydraulic pumps, fuel injectors) to monitor component vibration during performance testing. Its high data update rate (up to 2 kHz) and low noise meet aerospace industry standards, providing precise vibration data for validating accessory dynamic stability. This ensures compliance with aircraft safety regulations and supports the development of reliable engine components.

  1. Water Treatment Plant Pump Bearing Temperature Monitoring: Integrated into municipal water treatment plant water supply and sewage pump bearings to track temperature. Its over-temperature alarm detects bearing overheating caused by cavitation, impeller blockage, or insufficient lubrication, while the relay output (optional) activates backup pumps. By integrating with the plant’s SCADA system via Modbus RTU, it ensures continuous water supply and complies with environmental discharge standards.
