Description
This block reads a bridge type resistance sensor. These sensors typically require an excitation of
2 to 5 volts and a full scale output of 10 to 100 mV. To make this measurement, the Xpert makes
a single ended measurement of the reference voltage and a differential measurement of the input
voltage. The equation applied to the measured voltages is as follows:
Output = Slope * Vi/Vx + Offset.
The user set properties of the Bridge block are shown below. Note that the input is a differential
measurement so select an odd numbered input channel:
