  • Only one test set-up for the complete inertia tensor
  • Excellent accuracy
  • Ease of use

The InTenso series of instruments are full mass properties measurement instruments. They measure the weight, center of gravity location in 3 axes and the full inertia tensor: moment of inertia in 3 axes and product of inertia in 3 planes. The advantage of this system resides in the simplicity of use: the payload is only mounted in one configuration and all the mass properties are measured in that orientation.

InTenso is dedicated to payloads between 500 and 3,500 kg. This model was originally designed to test entire vehicles.

Other sizes are in the works. Please, contact us with your specific payload requirements for a custom-size instrument.

Measurement

The InTenso system is a non-linear pendulum. The payload is mounted to a platform suspended from rigid rods. Weight is measured first. Then, the payload is sent into a gentle random oscillation and the non-linear vibration of the payload is recorded via angular encoders together with the forces acting on it. A mathematical model derives the full mass properties of the body from the data collected.

The measurement software runs on Windows PC and provides all instructions for use on screen; it prompts the operator, reads the transducers, calculates Center of Gravity, Moment and Product of Inertia and prints a report.

The system as a whole is permanently calibrated. Individual load cells need to be re-zeroed and recertified periodically.

A proving body can be supplied as an option to verify that the system provides the proper output.

The accuracy of these systems is fully compatible with the requirements of the automotive industry.
