Transducer Interface

Hardware Overview

The TI transforms four inputs (amplified bridge signals) into two forces and one

moment by the following process:

• Applying a zero offset and scaling the signals

• Using a geometric matrix to transform the signals into two forces and one

moment in the transducer reference frame

• Using a cross-coupling matrix calculation to scale and sum the individual

signals into each output

• In spinning applications, using a rotational transformation to put the forces

and moments into a stationary reference frame

The TI conditions the transducer signals, producing four analog output signals

proportional to the following values:

• Longitudinal force (Fx)

• Vertical force (Fz)

• Driving/Braking moment (My)

• Angle output (θ)

Analog signals The force and moment signals are output from the TI in the form of ±10 V

full

scale analog signals. These signals can be used by most data acquisition systems.

The angle output is an analog voltage that is proportional to angular position. At

0° the output is 0 V. At 360°, the output is 5 V.
