Product Overview
The Multi-Channel Online Monitoring System is a high-performance multi-channel condition acquisition system developed for the complex operating conditions, variable loads, and transient dynamic characteristics of industrial key equipment during non-steady-state operation. Providing 8, 16, and 24-channel temperature-vibration integrated high-speed synchronous acquisition, it delivers high-quality data support for fault diagnosis, performance evaluation, and predictive maintenance.
Product Description
Rotating equipment in industrial settings rarely operates under the steady-state conditions that traditional monitoring systems are designed to capture. Variable loads, speed changes, start-stop transients, and process-induced dynamic variations create complex operating conditions that demand high-speed, multi-channel, precisely synchronized data acquisition to properly characterize. The Multi-Channel Online Monitoring System is engineered specifically for this non-steady-state monitoring challenge.
The modular design offers 8, 16, or 24-channel IEPE (Integrated Electronics PiezoElectric) temperature-vibration integrated acquisition channels, enabling scalable deployment matched to the monitored equipment's complexity. Each channel uses a 24-bit high-precision ADC (analog-to-digital converter) providing 16,777,216 quantization levels — the resolution needed to detect the subtle vibration signature changes that precede equipment failure. The maximum sampling rate of 102.4 kHz, combined with microsecond-level synchronization across all channels, ensures that phase relationships between measurement points are accurately captured — essential for advanced diagnostic techniques such as cross-channel phase analysis and mode shape identification.
The system supports dual sensor access: IEPE wired sensors for permanent, high-reliability installations and Zigbee wireless sensors for locations where cabling is impractical, with both sensor types supporting simultaneous acquisition. Two independent Ethernet interfaces serve different purposes: one connects to the analysis server for data storage and processing, while the other directly connects to PLC/DCS systems — enabling real-time equipment condition data integration into the plant control system without requiring an additional gateway. This direct-to-PLC/DCS capability eliminates the latency and reliability risk of intermediate processing.
Two audio noise high-fidelity sampling channels with 24-bit high-SNR ADC capture equipment acoustic emissions, enabling acoustic-based fault detection alongside vibration analysis. Eddy-current displacement sensor input and 4-channel rotational speed signal correlation acquisition enable order analysis — the technique of analyzing vibration data in the frequency domain relative to shaft speed, which is essential for equipment with variable operating speeds. The system supports 4M-long waveform acquisition with current/voltage waveform and vibration signal synchronous sampling, and multi-variable inputs including stress-strain and oil analysis data.
The dual-core 64-bit Cortex A53 processor provides the computational power for real-time signal processing. Communication modes include WiFi, 4G, 5G, Ethernet, fiber, and Zigbee. The mobile app enables direct communication for temporary waveform acquisition and remote configuration. EMC level-4 protection ensures electromagnetic compatibility in the electrically noisy industrial environment, and compliance with wind-power temperature-grade requirements extends applicability to the demanding wind-turbine monitoring market.
