Miniature Triaxial Accelerometer in 6.3-mm Cube

Measuring acceleration or vibration in small spaces poses problems for applications such as small component qualification, structural vibration and environmental stress screening. PCB Piezotronics, Inc., new miniature Integrated Circuit – Piezoelectric or ICP triaxial accelerometer addresses these space-constrained applications. With a 6.3 mm (0.25-in) cube form factor, the Model 356A03 delivers 10 mV/g sensitivity.

Other features of the piezoelectric sensor include a hermetic seal design with a low noise floor and high shock limit as well as a redesigned cable strain relief connection to provide improved shear and tensile strength. The CE certified 356A03 is compatible with any ICP signal conditioner or readout device that includes ICP power.

Making High Temperature Rotation Measurements

Jeff Watson, a systems applications engineer in the High Temperature Strategic Marketing Group of Analog Devices, explains the high temperature measurements in ADI’s demo at Sensors Expo 2011 to Randy Frank.

With the 175°C rated ADXL206 accelerometer and the 210°C rated AD8229 instrumentation amplifier, rotation can be measured inside an oven.

Kistler Single-Axis IEPE Accelerometer Weighs in at Just 3.5 Grams

Kistler’s recently announced Type 8640A accelerometer is an Integral Electronics Piezoelectric (IEPE) unit that has an IEEE TEDS (Transducer Electronic Data Sheet) option. Besides weighing only 3.5 grams, the 0.394 x 0.394-inch sensor has an integral 10-32 connector and a 5-40 UNC-2B stud mount as part of its hermetically-sealed, welded titanium housing. The internal ceramic cantilever beam sensing element is thermally compensated with a temperature coefficient of sensitivity of 0.1302 %/°F.

Designed for the multi-channel modal and structural analysis of small or thin-walled structures and components, the accelerometers are offered in ranges of ±5 g, ±10 g and ±50 g, with sensitivities from 100 to 1000 mV/g.

Meggitt Sensing Systems Ultra-small Triaxial Accelerometer

Measuring acceleration in a very small form factor can pose significant challenges. In addition to the right performance capability, the packaging and connectivity as well as the weight of the accelerometer must not interfere with the measurement. Designed for these types of measurements, Meggitt Sensing Systems’ Endevco model 35A ISOTRON triaxial accelerometer with its integral electronics offers a solution. Weighing 1.1 grams without its cable, the 35A avoids the undesirable effects of mass loading on small test structures.  The tri-axial accelerometer has a range of ±1000g with a typical voltage sensitivity of 5 mV/g. It comes with field repairable and factory replaceable fine gage wires (34 AWG) as output leads.
