1. A multi-channel, multi-range transducer for measuring a parameter, the transducer comprising N channels and M sensing elements, the M sensing elements centered on distinct calibration points of distinct measuring ranges, the M sensing elements distributed across the N channels of the transducer and operable over an entire operating range of the transducer, wherein the M sensing elements having adjacent measuring ranges are provided in different ones of the N channels such that each of the N channels consists of distinct and non-overlapping measuring ranges covering the entire operating range of the transducer.
 
5. A system for operating a gas turbine engine, the system comprising:
a multi-channel engine controller having a processor and a non-transitory computer readable medium having stored thereon program instructions executable by the processor for controlling the gas turbine engine; and
a multi-channel, multi-range transducer operatively connected to the engine controller for providing thereto a measured parameter from the gas turbine engine, the transducer comprising N channels and M sensing elements, the M sensing elements centered on distinct calibration points of distinct measuring ranges, the M sensing elements distributed across the N channels of the transducer and operable over an entire operating range of the transducer, wherein the M sensing elements having adjacent measuring ranges are provided in different ones of the N channels such that each of the N channels consists of distinct and non-overlapping measuring ranges covering the entire operating range of the transducer.
