Sensing Systems' Endevcomodel 7240C is a miniature
piezoelectric accelerometer with low bandwidth flat to 30 kHz was designed for
general purpose high-frequency vibration measurements.
Endevco model 7240C
offers low base strain sensitivity with a total package weight of 4.8 gm,
eliminating mass loading concerns. The unit is hermetically sealed to prevent
against environmental contamination and is a self-generating device which
requires no external power source for operation.
Signal ground of the Endevco
model 7240C is connected to the outer case of the unit. When used with one of
the supplied isolated mounting studs, the accelerometer is electrically
isolated from the ground. A specially designed low-noise coaxial cable is also
supplied for error-free operation. The sensor is for use within a variety
of automotive, aerospace, commercial aviation, general laboratory testing and
structural monitoring applications.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
