Stud Mounted IEPE Accelerometers
News Release from:
Measurement Specialties, INC.
Measurement Specialties recently released to production two new IEPE accelerometers for shock and vibration measurement. The Models 7104A (Side Connector) and 7105A (Top Connector) feature welded construction and wide bandwidth to >12kHz. These hermetic devices are offered in ranges ±50g to ±500g with operating temperatures from -55°C. to 125°C.
Their stud mounting and 10-32 connectors with optional cable, facilitates easy “out-of-the-box” installation. Adhesive mounting adapters and magnetic mounting adaptors are available upon request. Standard length of the detachable cable is 120 inches. Other lengths are available upon request.
Measuring < 0.75 inches in height and weighing <8.8 grams, these small stainless steel accelerometers can withstand ±10,000 g’s overshock while maintaining their 1% non-linearity specification. Their stable temperature performance is due to a proprietary bonding technique that does not require the use of epoxy...an adhesive commonly observed to cause sensor drift over temperature.
Both the 7104A and 7105A are IEPE devices that incorporate stable piezo-ceramic crystals in annular shear mode. Excited by 2-10mA (with 18-30 V compliance voltage), these sensors exhibit minimal residual noise and are offered in an optional TEDS configuration. Collectively, the performance and physical specifications of these units make them ideal for modal, high frequency and laboratory applications.
The Vibration Design Center in Aliso Viejo, CA spearheads Measurement Specialties' global initiative to expand its accelerometer and vibration sensing business with customers in the automotive, medical, military/aerospace and consumer goods industries. This center builds on the company's platform sensing technologies in silicon MEMS, piezoelectric polymer film, piezoelectric ceramic and bonded gage.
