EPRO MMS6620 Product Details
The EPRO MMS6620,launched by EPRO,a brand within the PRÜFTECHNIK Group,is a high-end multi-channel vibration and dynamic pressure monitoring module designed specifically for the complex condition monitoring needs of high-speed rotating machinery(such as gas turbines,aircraft engines,steam turbines,and high-speed compressors).The module integrates high-sampling-rate vibration signal acquisition,dynamic pressure measurement,temperature compensation,and real-time spectrum analysis.It supports simultaneous multi-parameter monitoring,high-speed data transmission,and advanced fault diagnosis.It is widely used for predictive maintenance of high-end equipment in industries such as power generation,aerospace,petrochemicals,and metallurgy.The following is a detailed analysis of the product’s positioning,core functions,technical specifications,application scenarios,and selection recommendations:
1.Product Positioning and Core Functions
System
PRÜFTECHNIK Condition Monitoring Platform:As the flagship module of the EPRO series of monitoring systems,the MMS6620 can operate independently or be integrated into advanced monitoring platforms such as VIBGUARD 7000 and VIBROWAVE Pro,enabling real-time visualization of equipment status,fault warnings,and in-depth data analysis.Module Type:
High-SpeedVibration+Dynamic Pressure Monitoring Module:Supports simultaneous acquisition of vibration(acceleration/velocity/displacement),dynamic pressure,temperature,and other parameters,meeting the complex monitoring needs of high-speed machinery(such as rotor dynamics analysis and aerodynamic excitation monitoring).
Core Advantages
Ultra-High-SpeedSignal Acquisition:Single-channel sampling rate up to 512kHz,supporting ultrasonic frequency band(20kHz-100kHz)vibration monitoring,capturing subtle fault characteristics of high-speed machinery(such as gear micropitting and premature bearing spalling).
Synchronous Dynamic Pressure Monitoring:Integrated high-frequency pressure sensor interface analyzes dynamic pressure signals such as combustion chamber pressure fluctuations,aerodynamic noise,and rotor blade pass frequency.
Multi-Parameter Synchronous Triggering:Supports simultaneous triggering of vibration,pressure,and temperature acquisition,ensuring temporal correlation of fault signals(such as analysis of combustion oscillation and vibration coupling).
Advanced Signal Processing:Built-in algorithms such as order tracking,envelope demodulation,and time-frequency analysis(STFT)support fault diagnosis of variable-speed machinery(such as variable-frequency drive pumps)and non-stationary signals.High-reliability design:Utilizing redundant power supplies,hot-swappable modules,and industrial-grade components,it withstands extreme operating temperatures of-40°C to+85°C and meets ATEX/IECEx explosion-proof certification(optional).
