Product Overview
The BBVM-FS10 is an ICP piezoelectric force sensor designed for vibration and dynamic testing. It measures dynamic tensile, compressive, and short-duration impact forces. Its center through-hole construction allows installation between a vibration exciter, mechanical structure, and test fixture for dynamic load measurement.
Used with a vibration exciter, the sensor supports excitation-force measurement and control. It can also be combined with acceleration or velocity sensors for mechanical impedance testing, modal testing, and structural dynamic analysis.

Operating Principle
When a dynamic load is applied, the internal piezoelectric element generates an electrical charge proportional to the force. Integrated ICP electronics convert this charge into a low-impedance voltage output for transmission, recording, and analysis through a signal conditioner and data acquisition system.
Typical Applications
- Impact-force testing and modal testing
- Vibration-exciter force measurement and control
- Dynamic tension and compression measurement on mechanical structures
- Mechanical impedance and transfer-function testing
- Vibration test rigs and structural dynamics testing
- Modal analysis combined with accelerometers
Compatible Equipment
- ICP signal conditioner
- Dynamic data acquisition system
- M5-to-BNC low-noise connection cable
- Vibration exciter and vibration control system
Installation Requirements
- Keep the mounting surfaces flat and clean to ensure uniform force transmission.
- Apply suitable preload through the center mounting hole and avoid uneven loading of the housing.
- Align the sensor axis with the direction of the measured force.
- Do not exceed the selected measurement range during testing.
- Secure the connection cable to minimize cable-motion effects on the dynamic signal.
