PCB Piezotronics, Inc. HIGH FREQUENCY INDUSTRIAL ICP® VELOCITY SENSOR VO622B01

The VO622B01 is a high-frequency industrial ICP¬Æ velocity sensor designed for precise measurement in various applications. It features a sensitivity of 100 mV/in/sec and a measurement range of ¬±50 in/sec, making it suitable for dynamic velocity measurements. The frequency range extends from 240 to 270,000 cpm (4 to 4,500 Hz) with a broader response of 180 to 540,000 cpm (3 to 9,000 Hz) at ¬±3 dB. This sensor has a resonant frequency of 1,800 kcpm (30 kHz) and a non-linearity of ¬±1%. It is built to withstand harsh environments, with an overload limit of 5,000 g pk and a temperature range of -65 to +250 ¬8F (-54 to +121 ¬8C). The enclosure is rated IP68, ensuring protection against dust and water ingress. Electrical specifications include an excitation voltage of 18 to 28 VDC and a constant current excitation of 2 to 10 mA. The output impedance is less than 100 Ohm, with an output bias voltage between 8 to 12 VDC. The sensor's physical dimensions are 7/8 in x 2.06 in (22 mm x 52.3 mm), and it weighs 3.3 oz (94 gm). It features a ceramic sensing element and a stainless steel housing, providing durability and reliability in industrial settings.
