    摘要： Transducer housing for mounting in a port in an engine combustion chamber has a metal diaphragm exposed to the combustion gasses. The pressure of the combustion gasses is transferred through an aluminum coupling disc which deflects a simply supported beam member. The beam member is formed of refractory material having epitaxially grown crystalline piezoresistors formed on one surface of the beam member and connected in a bridge circuit and is secured to a ceramic mounting disc. The aluminum coupling disc has a relatively high coefficient of thermal expansion which maintains a preload on the beam member for improved accuracy in spite of the low thermal expansion of the ceramic mounting disc. In an alternate embodiment, an expansion ring made of a material having a relatively high coefficient of thermal expansion is used to support a mounting disc on which the beam member is supported. The high expansion rate of the expansion ring maintains a preload between the beam member and a cup diaphragm by compensating for the relatively low expansion of the ceramic mounting disc.

    摘要： A transducer housing for mounting a port in a combustion chamber has a metal diaphragm exposed to the combustion gasses. The pressure of the combustion gasses deflects the diaphragm which locally deflects a simply supported beam. The beam is formed of refractory material having epitaxially grown crystalline piezoresistors formed on one surface of the beam and connected in a bridge circuit. Noble metal foil leads connect to the piezoresistors to form the bridge and provide attachment pads. The pads are noble metal welded to other noble metal foil pads provided on a ceramic substrate to form a sensor subassembly for mounting adjacent the diaphragm to form a transducer.

    摘要： A pressure sensor including a plate-shaped metal substrate; a glass layer provided on a surface of the metal substrate and mainly containing a partially devitrified enamel composition; a resistor element which is provided on a surface of the glass layer and has an electric resistance changed in accordance with the degree of strain thereof; and a pair of electrodes connected to the resistor element. The resistor element is provided so as to receive a stress, a pressure, or a load applied perpendicularly to a surface thereof. Alternatively, both surfaces of the metal substrate are provided with glass layers, respectively, and the resistor element is provided on one of the glass layers.
