Abstract
A sensing system, including: a sensing assembly, the sensing assembly having: a trim resistor; and a controller removably secured to the sensing assembly, the controller being configured to determine a resistance value of the trim resistor; a database in operable communication with the controller, the database having a plurality of resistance values, each identifying a pair of compensation values; a microprocessor receiving the resistance value of the trim resistor, a first signal and a second signal, the resistance value of the trim resistor being used to define a selected pair of compensation values from the database, one of the selected pair of compensation values is used to adjust the first signal and the other one of the selected pair of compensation values is used to adjust the second signal.
