Abstract

See full text

A resistance circuit for monitoring a support structure is provided. The resistance circuit may include a first set of resistors disposed at a belt-side and a second set of resistors disposed at a monitor-side. The first set of resistors may be configured to indicate one or more voltages thereacross corresponding to an effective resistance of the support structure. The first set of resistors may include at least one temperature-dependent resistor. The second set of resistors may be configured to indicate one or more voltages thereacross corresponding to an initial effective resistance of the support structure. The second set of resistors may include at least one switched resistor having an adjustable resistance capable of selectively approximating the initial effective resistance.
