ANDOVER, Mass., Nov. 5, 2014 (GLOBE NEWSWIRE) -- MKS Instruments, Inc. (Nasdaq: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has introduced the 902B Absolute Piezo vacuum transducer which integrates a The devices designed to do this, acousto-optic modulators, typically contain a crystal attached to a piezoelectric transducer. The sound waves propagating through the crystal modulate the intensity of light passing through it. But these devices are Ultrasonic sensors use the same principals as medical ultrasonography. piezoelectric transducers generate high-frequency sound waves and the reflected energy is measured to produce a three-dimensional image. This technique is capable of penetrating the MSI has designed transducers to withstand the most severe environments normally encountered in industrial applications, including temperatures ranging from -40°C to >150°C and pressures up to 25,000psi (170MPa). Frequencies can range from 25kHz to over 1MHz. Researchers at Penn State have demonstrated an acoustofluidic pump powered by a piezoelectric transducer about the size of a quarter. This reliable, inexpensive, programmable pump is a crucial feature for lab-on-a-chip devices that could make the diagnosis MKS Instruments, Inc. MKSI, +0.48% a global provider of technologies that enable advanced processes and improve productivity, has introduced the 902B Absolute Piezo vacuum transducer which integrates a MEMS-based Piezo sensor with a metal sealed, stainless .

These devices feature a very small package size Number 12 in the Clean Air Technologies Series. Highways, subways, etc. – platforms for piezo-electric transducers? I don’t consider myself to be an inventor or designer, but in the late 1980s I came up with what I thought was a feasible idea: make use .
