PCB Piezotronics, Inc. Accelerometer, ICP®, Triaxial 356A25

The PCB Piezotronics 356A25 is a triaxial ICP¬Æ accelerometer designed for general-purpose applications. It features a sensitivity of 25 mV/g and a measurement range of ¬±200 g peak, making it suitable for a variety of dynamic measurements. The frequency response spans from 0.5 to 6500 Hz at ¬±10% and up to 5000 Hz at ¬±5%, with a resonant frequency of at least 25 kHz. This accelerometer has a low broadband resolution of 0.0002 g rms within the 1 to 10,000 Hz range and exhibits non-linearity of less than or equal to 1%. It is capable of withstanding overloads of up to ¬±7000 g peak and operates effectively in temperatures ranging from -65 to +250 ¬8F (-54 to +121 ¬8C). The device is constructed with a ceramic sensing element and a titanium housing, ensuring durability and reliability. Electrical specifications include an excitation voltage of 20 to 30 VDC and a constant current excitation of 2 to 20 mA. The output impedance is ,⧠100 Ohm, with a bias voltage ranging from 8 to 12 VDC. The accelerometer is equipped with a 1/4-28 4-pin electrical connector positioned on the side, and it has a compact size of 0.55 in x 0.80 in x 0.55 in (14.0 mm x 20.3 mm x 14.0 mm) and a weight of 0.37 oz (10.5 gm). Overall, the 356A25 accelerometer is a robust choice for engineers seeking a reliable triaxial measurement solution in demanding environments.
