Performance Parameters Sensitivity tolerance: ±5% Transverse sensitivity: ≤5% Measurement repeatability: Stable for continuous long time monitoring Sealing performance: Hermetic seal for harsh environment
Structural Characteristics Hermetically sealed stainless steel sensor body. Internal piezoelectric crystal sensing assembly. Threaded base for stud mounting on equipment casing. Built-in low impedance amplifier circuit inside housing. Connector for signal cable connection.
Working Principle When equipment vibrates, internal mass block acts force on piezoelectric crystal. The crystal generates electric charge proportional to vibration acceleration. Built-in amplifier converts charge signal into low impedance voltage signal. The vibration signal is transmitted to monitoring module through signal cable for analysis, calculation and alarm judgment.
Installation Requirements Mount the sensor on flat, clean, rigid surface of bearing housing. Use matching stud for installation, ensure full contact between sensor base and equipment surface. Tighten mounting stud according to recommended torque value. Use dedicated shielded vibration signal cable. Route cable to avoid pulling force and friction. Ground sensor housing following Bently system grounding requirement.
