Enhancing Performance with Pressure Sensors

Pressure transducers have become an invaluable tool for the protection and optimization of industrial equipment, converting fluid pressure into variable electrical signals that can monitor and control a system. The Gems portfolio includes general purpose and high performance pressure transducer options.

Types of Pressure Transducers:

CVD Pressure Sensors

Gems Chemical Vapor Deposition (CVD) pressure transducers provide an effective method of overcoming the often severe limitations of other low-cost pressure measuring products. A stateof-the-art ASIC chip in each transducer provides greater linearity correction than traditional thermal compensation methods.

Thin Film Pressure Sensors

Sputtered thin film technology provides years of worry-free measurements under demanding real-world conditions. Sputtered metallic strain gauge sensors have terrific thermal properties and superior stability specifications. Ideal for harsh applications demanding long-term service where precise laboratory-type measurements are required.

Capacitance Low Pressure Transducers

Capacitive transducers are simple, durable and fundamentally stable. Variable capacitor technology, a rugged physical configuration, stainless steel wetted parts and a careful marriage of the mechanical assembly to the electronic circuitry combine to create highly repeatable transducers with low hysteresis and only .5% long-termdrift full scale per year, for low pressure applications. This large family of sensors includes models for positive pressures to 10,000 psi (700 bar), absolute vacuums, differential pressures, barometric pressure, low pressures (0-15 psi/ 0-1 bar), and clean-in-place 3A sanitary applications.

MMS Pressure Transducers

These transducers employ a micromachined silicon (MMS) diaphragm to detect pressure changes. The silicon diaphragm is protected from the media by an oil-filled 316SS isolation diaphragm; they react in tandem to process fluid pressure. MMS sensors utilize common semiconductor manufacturing techniques that allow for high proof pressure, good linearity, great thermal shock performance and stability in a thin sensor package.
