A Silicon-on-Sapphire Pressure Transducer has unsurpassed levels of performance for aerospace and other precision measurements. They provide high (5mV/V) sensitivity with excellent accuracy and stability over widely varying temperatures ranging to as low as -300°F or as high as +1000°F. Sapphire diaphragms are compatible with virtually all media encountered in unfriendly environments. Our quality system is based on AS9100 with Perry Johnson as our registrar.

Piezoresistive silicon on sapphire diaphragms form a homogeneous single-crystal radiation-hardened structure with virtually undetectable hysteresis. Since sapphire is a perfect electrical insulator there is no need for diode isolation junctions found in a traditional SOI piezoresistive pressure transducer.

A proprietary hermetic seal between the sapphire diaphragm and the electron-beam welded stainless steel case provides the ultimate in temperature coefficient match between internal structures. The seal also allows direct contact with corrosive and conductive media without use of a barrier diaphragm or transfer fluid.

Sensonetics' pressure transducers are designed to comply with Military Standards for vibration, acceleration, shock, sand, dust, salt, humidity, EMI, radiation and other environments. The case is internally stress isolated to inhibit response to mounting torque and other external stresses. The Sensonetics SEN-100 military grade transducer has precision, accuracy and reliability that can support the most demanding requirements in all pressure transducer applications.
