  • Patent number: 7478002
    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.

  • Publication number: 20080183414
    Abstract: 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 th

  • Publication number: 20070079597
    Abstract: A system and a method for monitoring operation of an exhaust gas treatment system using an exhaust gas sensor in accordance with an exemplary embodiment is provided. The exhaust gas treatment system has an exhaust pipe configured to receive exhaust gases. The exhaust gas treatment system has an SCR catalyst coupled to the exhaust pipe. The exhaust gas treatment system has a urea delivery system configured to delivery urea upstream of the SCR catalyst. The exhaust gas sensor has an ammonia sensing electrode communicating with exhaust gases downstream of the SCR catalyst. The method includes generating a first output signal utilizing the ammonia sensing electrode, the first output signal being indicative of a first ammonia level. The method further includes generating a second output signal to induce the urea delivery system to deliver a predetermined flow rate of urea upstream of the SCR catalyst. The second output signal is based on the first output signal.
