| ® Additional Bend Sensor Resis These circuits are slightly modified versions ofthe resistance-to-voltage converter detailed on Figure 1.7. Please see Figure 1.7 on the previous page for more detail. The output of Figure 1.8 is described by the equation: VoUT = Vref/2 Rc/RBend Sensor®] The output swing ofthis circuit is from (Vref/2) to OV. In the case where RG is greater than RBend sensor®, the output will go into negative saturation. The output of Figure 1.9 is described by the equation: VoUT = Vref/2 Rc/RBend Sensor®] The output swing ofthis circuit is from (Vref/2) to Vref. In the case where RG is greater than RBend Sensor®, the output will go into positive saturation. For either ofthese configurations, a zener diode placed in parallel with RG will limit the voltage built up across RG. These designs yield one-halfthe output swing ofthe previous circuit, but only require single sided supplies and positive reference voltages. |
