Abstract:
1. A gas sensor apparatus, comprising: a flange; a bellows; said bellows supported by said flange; a port, said port communicating gas with and to said bellows urging said bellows in a vertical direction; a base plate, said base plate supported by said flange; a bellows coupling, said bellows coupling includes a pivot portion; a vertically movable lever; said bellows residing between said flange and said bellows coupling; said bellows coupling residing between said bellows and said lever, said pivot portion of said bellows coupling engaging said vertically movable lever in a vertical direction in response to the temperature and pressure of said gas; an adjustable bias mechanism, said bias mechanism engages said lever; a bimetallic element, said bimetallic element affixed to said lever and to said base plate; an electronic distance sensor, said electronic distance sensor includes a first element affixed to said lever and vertically movable therewith, and a second element that is stationary with respect to said base plate; an electronic microcontroller in communication with said electronic distance sensor; said electronic distance sensor detecting said distance between said first element and said second element of, said electronic distance sensor outputting a first signal representative of said distance between said first and second elements to said microcontroller; a temperature sensor, said temperature sensor outputting a second signal representative of said temperature of said gas to said electronic microcontroller; said microcontroller determining a temperature compensated pressure of said gas; and, said microcontroller determining the gas density.
