摘要： A sensor system includes a plurality of strain gauges and a passive compensation circuit. The plurality of strain gauges are configured to provide an output voltage indicative of a sensed pressure using an input voltage. The passive compensation circuit that includes a span resistor, first and second compensation resistors, and a zero offset resistor. The span resistor is connected between an input voltage and the pressure sensor and is configured to control a range of an output voltage for a pressure range of the pressure sensor. The first and second compensation resistors are operatively connected in parallel with the pressure sensor and are configured to control current provided to the pressure sensor. The zero offset resistor is operatively connected between the first and second compensation resistors and the pressure sensor and is configured to control a base value of the output voltage for zero pressure.

摘要： A dielectric header sub-assembly includes a header body with opposed first and second surfaces and a side wall. The first and second surfaces define a header axis extending therebetween. The side wall extends from the first surface to the second surface. The second surface includes a tapered portion. A dielectric header sub-assembly includes a bore. The bore extends from the first surface to the second surface. A first bore opening of the bore proximate to the first surface is greater in area than a second bore opening of the bore proximate the second surface. A method of assembling a header sub-assembly includes inserting an electrical connector into a bore of a header body, applying an active braze filler material into the bore and applying heat to braze the active braze filler material to the header body and the electrical connector.
