PCB Piezotronics, Inc. Accelerometer, ICP®, Triaxial 356B21

The PCB Piezotronics, Inc. model 356B21 is a triaxial ICP¬Æ accelerometer designed for a wide range of applications. It features a sensitivity of 10 mV/g and a measurement range of ¬± 500 g pk, making it suitable for high dynamic measurements. The frequency response is robust, with a range of 2 to 10,000 Hz for the y and z axes, and 2 to 7,000 Hz for the x axis, ensuring accurate data capture across various conditions. This accelerometer has a resonant frequency of ,â 55 kHz and a broadband resolution of 0.004 g rms, indicating its capability to detect small vibrations. It exhibits low non-linearity (,⧠1%) and transverse sensitivity (,⧠5%), which enhances measurement accuracy. The device can withstand overloads of up to ¬± 10,000 g pk and operates effectively in temperatures ranging from -65 to +250 ¬8F (-54 to +121 ¬8C). The accelerometer is housed in a hermetically sealed titanium casing, ensuring durability and reliability in harsh environments. It has a compact size of 0.4 in x 0.4 in x 0.4 in and weighs 0.14 oz, making it easy to integrate into various systems. The electrical specifications include an excitation voltage of 18 to 30 VDC and a constant current excitation of 2 to 20 mA, with an output impedance of ,⧠200 Ohm. Included with the accelerometer are a 10 ft cable and various mounting accessories, facilitating installation and use. This model is suitable for engineers looking for a reliable and precise accelerometer for dynamic measurement applications.
