摘要
A gas density transducer including: a piezoresistive bridge sensor operative to provide an output indicative of an applied pressure, a computing processor having multiple inputs and at least one output, with the output of the bridge sensor coupled to an input of the processor; a temperature sensor coupled to an input of the processor for providing at an output a signal indicative of a temperature of the bridge sensor, the output of the temperature sensor coupled to an input of the processor; and, at least one memory accessible by the processor and having stored therein: compensation coefficients for compensating the output of the bridge sensor for temperature variation; an algorithm for solving Van der Waal's equation; and, code for providing at an output of the processor a signal indicative of a gas density when the bridge is subjected to a gas containing environment.
