Model 833 is a high-sensitivity triaxial accelerometer which simultaneously measures acceleration and low-frequency vibration in three mutually perpendicular axial. 833 is triaxial capacitive accelerometer family utilizes a silicon Micro-Electro-Mechanical System (MEMS) variable capacitance sensing element. The output signal is scaled as a voltage which is proportional to the applied acceleration, signal format is single-ended 2.5±2V. The accelerometer is powered by a single regulated supply between 5.5 to 30 Vdc. Thermal drift has been compensated by internal circuit for the best environment stability. The sensing element and electronics are contained in a lightweight 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 M3 metric screw or adhesive. 833 is well-suited for a wide variety of R&D or OEM applications requiring low frequency measurements and compact size.
