General Purpose Piezoelectric Accelerometers

Piezoelectric accelerometers offer tremendous versatility for shock and vibration measurements. These rugged sensors can withstand adverse environmental conditions. A wide variety of configurations are available to support multiple application requirements. Specialty units are also available through mechanical or electrical design adjustments or additional qualification testing.
There are two broad categories for piezoelectric accelerometers – those that contain built-in signal conditioning electronics (IEPE type) and those that do not (Charge Output(PE) type). Generally, IEPE accelerometers are preferred, due to ease of use and lower system cost. Charge Output accelerometers are used for high temperature environments, which would otherwise destroy the electrical components contained in an IEPE type. Triaxial accelerometers offer simultaneous measurements in three orthogonal directions permitting the entire vibration being experienced by a structure to be analyzed. Each unit incorporates three separate sensing elements that are oriented at right angles with respect to each other. Multi-pin electrical connectors, individual cable leads, or multiple coaxial connectors provide the signal outputs for the x, y, and z-axis acceleration. The use of triaxial accelerometers has gained popularity since the desire for in-depth structural vibration analysis has increased and multi-channel data acquisition costs have declined. These devices are vital tools for structural analysis testing requirements.

General Purpose Piezoelectric Accelerometers

Motion of a rigid body can be characterized within six degrees of freedom. Providing mechanical excitation to simulate all of this motion as may be encountered in the real world can entail a variety of test machines. Regardless of the apparatus, the goal is always to ensure that the product under test can adequately perform, and reliably survive, in the environment in which it will be deployed, or to which it will be exposed during transport. YMC accelerometers provide the measurement signals needed to control the vibratory input and to analyze the product’s reaction to such testing. Did the test achieve the acceleration amplitudes and frequencies desired? Did the product react in a consistent manner? Did any components or mounting techniques become altered? These are just a few of the questions that can be verified by analyzing the signals generated by YMC accelerometers.
Packaging a product for safe transport is essential to ensure its survival from the factory to the end-user. A good package design requires testing to determine its effectiveness at restraining or cushioning the product from transport and accidental forces. YMC accelerometers are instrumental in measuring both the impact and vibration experienced by the outer container and the product. The difference between these measurements provides useful data for quantifying the effectiveness of the packaging materials and the package design.
