Model 817 is a high sensitivity accelerometer which measures shock acceleration and low-frequency vibration. 817 is an accelerometer utilizes a silicon Micro-Electro-Mechanical System (MEMS) sensing element. The sensing element consists of a very small inertial mass, as the mass deflects under acceleration, the sensing element generates an analog output signal proportional to the applied acceleration. This output signal is scaled as a voltage which is proportional to the applied acceleration. The accelerometer is powered by a single regulated supply between 5 to 10 Vdc. Thermal drift has been compensated by internal circuit for the best environment stability. The sensing element and electronics are contained in a miniature housing with an integral cable terminated by pigtails or specified connector. Signal ground is isolated from the test object that benefit from the anodized aluminum housing. The accelerometer can be mounted by adhesive. 817 is well-suited for a wide variety of R&D applications requiring shock survivability and precision measurements.
