The Amphenol / PCB Piezotronics 353B52 is a high-sensitivity quartz shear ICP accelerometer engineered for precision vibration measurement in demanding industrial and laboratory environments. The shear element design minimizes base strain effects, delivering accurate and repeatable acceleration data across a wide frequency spectrum. ICP integrated electronics eliminate the need for external charge amplifiers, streamlining signal conditioning and reducing system complexity.
Technical Specifications
Sensing & Performance
• Sensing element: Quartz
• Design: Shear element
• Sensitivity: 500 mV/g
• Frequency range (±5%): 1 to 2000 Hz
• Type: ICP® accelerometer
Electrical & Power
ICP technology requires a constant current power supply. Output impedance and excitation voltage specifications follow standard ICP conventions, providing low-impedance voltage output compatible with industrial data acquisition systems.
Connectors & Cabling
• Connector: 10-32 top connector
• Cable: Coaxial BNC to 10-32 configuration (10 ft standard)
Mechanical
Mounting provisions support multiple fastener options including 5-40 UNC, M3, 10-32 UNF, M5, 1/4-28 UNF, M6, and M8 threads. Mounting torque ranges from 4–5 inch-pounds for smaller threads to 2–5 foot-pounds for larger threads. Optimal mounting requires a flat surface within 0.001 in. (0.03 mm) TIR with Ra finish or better. Application of silicone grease at the mounting interface enhances coupling and thermal stability.
