This document illustrates the merits of wired IEPE piezoelectric vibration monitoring. Compared with wireless LoRa MEMS monitoring, the wired solution realizes real‑time collection of complete raw vibration waveforms with high sampling rates. It delivers reliable communication free of wireless interference and requires no battery maintenance. Capable of transient shock capture and advanced spectrum analysis, it is particularly fit for early‑fault diagnosis and long‑term continuous online monitoring of pumps, motors and bearing‑equipped rotating machinery.
This solution introduces an edge‑cloud collaborative online condition‑monitoring system for water pump units. Using IEPE accelerometers and Pt100 temperature sensors, it collects vibration velocity and temperature data to detect typical faults such as bearing wear, rotor unbalance and cavitation. Supporting local graded alarms and multi‑protocol upload to private cloud platforms, it enables predictive maintenance, reduces unplanned shutdown risks and improves pump‑unit O&M efficiency.
Rotating machinery such as key pumps and fans operate in continuous running conditions for long‑term service. Issues including unbalance, misalignment, mechanical looseness, bearing faults, gear failures and other defects may occur in components such as bearings, rotors, couplings, gears and foundations during operation. Conventional manual inspection is subject to long monitoring cycles, insufficient data continuity and delayed detection of anomalies. Therefore, this solution adopts the technical architecture consisting of vibration sensors, edge‑computing acquisition units and data analysis platforms to implement continuous condition‑based vibration monitoring for critical pumps, fans and other equipment. The system acquires operating‑condition signals of equipment via vibration, displacement and temperature sensors installed at key measuring points of equipment. Signals are wired to edge‑computing acquisition units, which complete data acquisition, signal processing, feature‑value
