ABB 100472-012 Product Details
The ABB 100472-012 is a high-performance vibration sensor launched by ABB,a core component of its Condition Monitoring and Predictive Maintenance solutions.This product is typically a uniaxial or triaxial piezoelectric accelerometer(IEPE type),designed specifically for vibration monitoring of industrial rotating machinery(such as motors,pumps,fans,compressors,and steam turbines).Featuring high accuracy,wide-band response,and strong environmental adaptability,it is widely used in industries such as power,oil and gas,chemicals,metallurgy,and rail transportation.The following provides a detailed description of its functional characteristics,technical parameters,application scenarios,and advantages:
I.Product Overview
Model:100472-012
Category:
Piezoelectric accelerometer(IEPE type):Based on the piezoelectric effect of piezoelectric ceramic materials,it converts mechanical vibration into a charge signal.With built-in signal conditioning circuitry(IEPE),it outputs a low-impedance voltage signal,making it suitable for dynamic vibration measurement.Available configurations:Single-axis or tri-axis measurement(please confirm model variant,e.g.,100472-012-01 for single-axis,100472-012-03 for tri-axis).
Core Positioning:
Real-time monitoring of vibration acceleration,velocity,or displacement of mechanical equipment,providing critical data for equipment condition assessment,fault diagnosis,and predictive maintenance.
Seamlessly integrates with ABB’s 800xA Condition Monitoring system,ABB Ability™Condition Monitoring Services,or third-party data acquisition systems(DAQ).
II.Core Functional Modules
Vibration Signal Detection
Detection Principle:
Piezoelectric ceramic materials generate an electric charge when subjected to mechanical vibration.The built-in IEPE circuit converts the charge signal into a voltage signal(e.g.,±5V or±10V),facilitating long-distance transmission and resisting interference.
Detection Parameters:
Acceleration:Measures peak value,effective value(RMS),or frequency spectrum of vibration acceleration in m/s²or g(1g=9.81 m/s²).Velocity/Displacement:Acceleration signals are converted to velocity(mm/s)or displacement(μm)via an external integrator or internal circuitry for vibration severity assessment.
Multi-band Monitoring
Frequency Response:
Typical bandwidth:0.5Hz to 10kHz(extendable to 20kHz on some models),covering low-frequency vibrations(such as imbalance and misalignment)to high-frequency vibrations(such as bearing faults and gear meshing).
Dynamic Range:
High signal-to-noise ratio(SNR)enables detection of weak vibration signals(such as early-stage bearing defects).The measurement range is selectable from±10g to±500g(depending on the model configuration).
