Prior to the founding of SMD in 1979, thin-film strain gauge technology had been limited to aero-space and other ultra-high accuracy applications. The development of SMD's proprietary thin-film process technology has yielded economic and performance benefits enabling the company to consid-erably expand its served applications, including medical, industrial, automotive, and process control. SMD thin-film sensors have significant advantages over silicon, foil strain gauge, capacitance, and other sensing technologies: □ Substantially improved long-term stability □ Lower power consumption □ Materially better temperature effects □ Flexible technology for unique shapes and sizes □ Inorganic dielectric materials			LEADING EDGE TECHNOLOGY...
	These and other enhancements herald a revolution in sensor technology, making possible the use of feedback in numerous products.

		SMD provides a seemingly infinite variety of sen-sors to accurately measure force, pressure, acceleration, and other physical parameters. While a few standard products are shown on the facing page, about 90% of SMD products are custom designed. These sensors meet the more specialized needs of OEM's. SMD's peerless engineering team designs sensors for unique requirements and aggressive cost targets. Typical specialized require-ments include small sizes, high temperature, low capacities, "Cenelec" dielectric, and overload-proof sensors. SMD's familiarity, especially with state-of-the-art medical products, has led to the development of complete, value-added, SMD produced subassem-blies which incorporate one or more sensors, signal conditioning electronics, and other features.

				Products range from sensors to fully pack-aged transducers all the way to data acquisition systems. This value-added capability is becoming one of the fastest growing parts of the business.

While SMD sensors are used in a vast array of applications from automotive to automation and undersea to outer-space, two markets stand out as extraordinary opportunities: medical instrumentation and pressure measurement. Medical instrumentation manufacturers are adding sensing capabilities for closed-loop feedback control at an ever increasing rate. SMD's extensive experience in design (over 20 years) combined with the flexibility of its proprietary thin film technology, position the company as an unparalleled medical sensor supplier. Inorganic dielectrics linked with precision thin film resistor circuits are ideal for medical sensing requirements. Applications include noninva-sive disposable-set pressure sensing, reagent reservoir flow and weight sensing, tocodynamometers, medical scales, bag sensing, plus orthopedic and physical therapy. Pressure transducers are an ideal application for the proprietary sputtered thin-film strain gauge technology. Long-term stability is so superior that SMD sensors are the core sensing technology in some pressure calibrators used to calibrate other manu- facturer's pressure transducers! Temperature coefficients are orders of magnitude better than silicon transducers and are linear from -40°C to +150°C and

Diaphragm sensors can include integral RTD's, 500Vac dielectric strength, and ranges of 30 psi through 30,000 psi (2 bar through 2000 bar). Lower range pressure sensors to inches-of-water full scale are available.
