Wire length
The maximum wire length depends on the total resistance and total capacitance in the
transmitter loop for each channel. The model used to determine the maximum allowed wire
resistance and wire capacitance between the transmitter port (T) and the receiver port (R) is
shown in the figure.
Rext is the total wire resistance, and Cext is the total wire capacitance (to ground, or shield).
The switch symbolizes the sensor, placed halfway in the T-R loop (as indicated by having half
of Rext/Cext on each side). Iext is the current drawn by the sensor for its operation and/or
other external loads. The maximum allowed wire resistance, Rext, vs. the externally drawn
current Iext is listed in the table.
