description A sensing system, comprising: a sensing assembly, the sensing assembly having: a trim resistor integrally formed with the sensing assembly, the trim resistor having a resistance value; a first sensing element for providing a first signal in response to a first sensed condition; a second sensing element for providing a second signal in response to a second sensed condition; and a controller removably secured to the sensing assembly and receiving the first signal and the second signal, the controller being configured to determine the resistance value of the trim resistor; a database associated with the controller, the database having a plurality of resistance values, each resistance value in the database identifies a pair of compensation values; a microprocessor associated with the controller, the microprocessor receiving the resistance value of the trim resistor, the first signal and the 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 to provide a first adjusted signal and the other one of the selected pair of compensation values is used to adjust the second signal to provide a second adjusted signal.
