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 1 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.
