Abstract: A pressure transducer comprising a flexible member made of amorphous quartz and a crystalline quartz sensor are coupled together without an adhesive material. Instead, the amorphous quartz and the crystalline quartz sensor are coupled together at the molecular level. In some embodiments, the crystalline quartz sensor remains in compression or tension during the entire operating range of the pressure transducer. In one embodiment, the crystalline quartz sensor is pre-stressed in either compression or tension when the pressure transducer is exposed to atmospheric pressure. In one embodiment, pressure transducer is located in pressure stabilizing system.
