Pizo-electric Sensors
Vibro-meter

The CA202 piezoelectric accelerometer is available in different versions for different industrial environments: Ex versions for installation in potentially explosive atmospheres (hazardous areas) and standard versions for use in nonhazardous areas. The CA202 piezoelectric accelerometer is designed for heavy-duty industrial vibration monitoring and measurement.

Most force sensors are based on an elastic or spring element: the force generates a deformation that is measured by some displacement sensor. The elasticity of the spring element determines the sensitivity of such sensors. A high sensitivity requires a large deformation, which is achieved by a low stiffness of the spring element. Such a large displacement, however, could unintentionally affect the structure in which the force has to be measured. A piezoelectric force sensor, on the other hand, responds directly to an applied force: the associated deformation is in most cases negligibly small, assuring small loading errors in the force measurement. Although force is the primary quantity that is measured by a piezoelectric sensor, other quantities such as pressure, strain, and acceleration can easily be measured as well, using a proper construction.
