An example of this type is the capacitance diaphragm gauge (42), in which a thin metal diaphragm stretched between two electrodes deflects away from its equilibrium position with the application of pressure; the deflection changes the capacitance between the diaphragm and the electrodes, and this change is converted to a pressure indication by conditioning electronics.
And at last week's SEMICON West trade show, we introduced new products, expanding our line of innovative SKY[R] CDG Capacitance Diaphragm Gauges and featuring the Sion[TM] RF Detector, the only ultra-fast, ultra-small plasma arc detector.
July 11 /PRNewswire-FirstCall/ -- Mykrolis Corporation , a leading supplier of components and subsystems to the semiconductor industry, today announced the release of the XacTorr CMC series of compact capacitance diaphragm gauges (CDGs) for vacuum processes that provide accurate total pressure measurement independent of gas composition.
INFICON Holding AG (SWX Swiss Exchange and NASDAQ: IFCN), a leading manufacturer of vacuum instrumentation and advanced process control software for the semiconductor and related industries, will introduce the TripleGauge(TM) Bayard-Alpert Pirani Capacitance Diaphragm Gauge at SEMICON West 2003, San Francisco.
