May 31, 2012, San Juan Capistrano, California, USA – Meggitt Sensing Systems, a Meggitt group division, today announced that it will be showcasing its latest MEMS-based sensor and transducer technologies, among other items, at Sensors Expo & Conference, June 6 and 7, 2012, at the Donald E. Stephens Convention Center in Rosemont, Illinois.
Held annually for more than 25 years, the Sensors Expo & Conference is the only North American industry event that is exclusively focused on sensors and related integrated systems, technical innovation and leadership. Sensors Expo & Conference identifies cutting-edge trends; explores them in an informative conference program; and reflects those trends throughout the exhibit floor with new product announcements and key technology-focused areas, such as Energy Harvesting, MEMS and Wireless, showcasing hundreds of exhibitor products and services. This year marks Meggitt’s twenty-fifth as an exhibitor at the annual expo, where the company’s technical experts will be on-hand to offer product information, active demonstrations and applications engineering expertise at Booth 1108.
MEMS sensing technologies on display will include the Endevco® model 7274 series of rugged, undamped, high-g piezoresistive triaxial shock accelerometers, also nominated for a 2012 “Best of Sensors Expo” Award. With a frequency response extending down to dc (steady state), the 7274 series is designed to measure long duration transient shocks while allowing for accurate external single and double integration of critical velocity and displacement acceleration data, for high-g shock measurements in three mutually perpendicular axes. This high-accuracy Meggitt product technology offers 20 years of field-proven pedigree across thousands of installations. Available in four ranges of 2000 g; 6000 g; 20,000 g; and 60,000 g, the series design incorporates three sensors mounted in a triaxial configuration within a single housing. This construction allows for a sensor with high resonance frequency, ruggedness to 3x over-range and zero damping, for minimal phase shift over the transducer’s useful frequency range. Because units are undamped, they also accurately respond to fast rise times and short duration shock motion. The series also features simple screw mount installation with factory controlled cross-axis performance, making them more cost-effective and easier to install than three similar-type single axis accelerometers with a mounting block.
Also featured will be the Endevco® model 7280A series, a family of lightly damped single axis high-g piezoresistive shock accelerometers, designed to support pyroshock, weapons testing, high-shock data recorders, missiles, munitions and other demanding requirements. These rugged sensors offer superior survivability to 4x over-range and minimum zero shift after shock, with higher impedance and lower power consumption than legacy models. Offered in ranges of 20,000 g and 60,000 g, the series design incorporates Meggitt’s new lightly damped MEMS sensing element, specially engineered for lower power consumption. Input voltage can be customer-specified, with 10V available as standard. Model 7280A series units incorporate its MEMS sensing element within an industry standard screw mount package, while the model 7280AM4 series is offered within a standard stud mount package. Occupying the same footprint as the industry best-selling Endevco® 7270A series, the 7280A is further designed to serve as a drop-in replacement for high-g shock measurement applications in which a legacy sensor may be in use, but where exceptional survivability may be prioritized over higher bandwidth, or where use of a sensor with light damping may offer certain testing advantages.
Please note that global sale of the aforementioned products are subject to International Traffic in Arms Regulations (ITAR), and as such, a license is required for all non-US shipments, with the product also potentially subject to other restrictions on its sale and use.
Also on display will be the Endevco® model 40931, a low-cost MEMS-based flip-chip mountable piezoresistive pressure transducer die, designed to provide high-accuracy, high-repeatability performance within medical OEM, surface airflow and other pressure measurement applications, and particularly, those which call for high output within a micro-miniature package. With a 0 to 15 psia measurement range and 200 mV full-scale output (5 Vdc excitation), the highly compact Endevco®model 40931 measures just 1.65 mm long by 1.2 mm wide by 0.4 mm tall. A uniquely sculptured silicon diaphragm design provides high sensitivity, high overpressure capability and a combined 0.5% non-linearity, non-repeatability and hysteresis specification, making it one of the most accurate pressure transducers of its size and type on the market today. Four connection pads allow for the sensor to be “flip-chip” mounted to a circuit or substrate using conductive epoxy. The MEMS pressure sensing element, located on the top of the sensor package, enables surface mounting and serves as the active sensing element for absolute pressure measurements.
All MEMS sensing elements used in Endevco® accelerometers and pressure transducers are machined in-house at Meggitt’s own ISO9001 certified MEMS manufacturing facility in Sunnyvale, California, USA, where vertically integrated manufacturing processes allow for full control of product quality, from component through to finished product. All Endevco® sensors and instrumentation are also backed by a five-year comprehensive product warranty, with selected models available at discounted rates under Meggitt’s Endevco® Incentives program.
