Functional Features Piezoelectric sensing principle for absolute casing vibration measurement. Hermetically sealed stainless steel housing for moisture and corrosion resistance. Wide frequency response to capture low-frequency and high-frequency vibration signals. Built-in low impedance amplifier circuit to reduce transmission interference. Compact size for installation on bearing housing and equipment casing. High shock resistance for heavy-duty industrial rotating machinery.
Application Scenarios Bearing housing vibration monitoring of steam turbine and gas turbine. Casing vibration measurement of centrifugal compressor, large fan and pump. Power generation unit rotating equipment condition monitoring. Oil and gas plant critical machinery protection system. General industrial heavy rotating equipment online vibration supervision.
Structural Characteristics Hermetically sealed stainless steel sensor body. Internal piezoelectric crystal and built-in charge amplifier assembly. Threaded base for stud mounting on equipment casing. Connector interface for vibration signal cable connection. Anti-vibration internal fixed structure for internal sensing components.
Working Principle When the equipment casing vibrates, the internal inertial mass applies force on piezoelectric crystal. The crystal generates electric charge proportional to vibration acceleration. The built-in amplifier converts charge signal into low impedance voltage signal. The vibration signal is transmitted to Bently monitoring module via dedicated shielded cable for vibration calculation and alarm judgment.
Installation Requirements Mount sensor on flat, rigid and clean surface of bearing housing. Use matched stud for installation and tighten to recommended torque. Connect dedicated shielded vibration signal cable to sensor connector. Route cable to avoid tension, friction and sharp edge cutting. Ground sensor housing according to Bently system grounding specification. Check signal output quality after installation.
