PCB Piezotronics, Inc. ICP® Accelerometer 352A26

The ICP¬Æ Accelerometer model 352A26 from PCB Piezotronics, Inc. features a sensitivity of 10 mV/g and a measurement range of ¬±500 g pk. It operates effectively within a frequency range of 2.0 to 10,000 Hz (¬±5%) and has a resonant frequency of ,â 70 kHz. The device exhibits a broadband resolution of 0.003 g rms and a non-linearity of ,⧠1%. Designed for robust applications, the accelerometer has an overload limit of ¬±5000 g pk and operates within a temperature range of -65 to +250 ¬8F (-54 to +121 ¬8C). The electrical specifications include an excitation voltage of 22 to 30 VDC and a constant current excitation of 2 to 20 mA. The output impedance is ,⧠200 Ohm, with a bias voltage ranging from 9 to 16 VDC. The accelerometer is compact, measuring 0.11 in x 0.34 in x 0.16 in (2.8 mm x 8.6 mm x 4.1 mm) and weighs only 0.007 oz (0.2 gm). It features a ceramic sensing element with a shear geometry, housed in anodized aluminum and sealed with epoxy. The electrical connection is made via a 3-56 coaxial jack positioned on the side, and it is designed for adhesive mounting. Supplied accessories include a 10 ft coax cable and a removal tool.
