Model 810 is a high-sensitivity, low noise accelerometer which measures acceleration and low-frequency vibration. 810 is a capacitive accelerometer family utilizes a silicon Micro-ElectroMechanical System (MEMS) variable capacitance sensing element. The sensing element consists of a very small inertial mass and a flexure element cantilever positioned between two plates. As the mass deflects under acceleration, the capacitance between these plate changes. AC excitation and synchronous amplitude demodulation circuitry contained in the accelerometer's internal signal conditioner provides 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 output signal format is single-ended 2.5±2V. The accelerometer is powered by a single regulated supply between 8 to 36 Vdc. Thermal drift has been compensated by internal circuit for the best environment stability. The sensing element and electronics are contained in a lightweight hermetic housing with a 4-pins connector. The mating cable 13M1-L terminated by pigtails or specified connector(optional) is available. Signal ground is isolated from the test object. The accelerometer can be mounted by M3 metric screw or adhesive. 810 is well-suited for a wide variety of R&D applications requiring precision measurements and packaging for demanding application and handling needs.
