USB Powered, Two Channel ICP® Sensor Powered Conditioner

February 9, 2004, Depew, NY - The Vibration Division of PCB Piezotronics, Inc. introduces a pocket sized dual channel ICP® sensor signal conditioner. Model 485B36 offers the low noise performance found in battery powered signal conditioners, but obtains its power from a computer's Universal Serial Bus (USB) port. Besides providing the sensor with the required constant current supply, the 485B36 decouples the sensors bias voltage from the measurement signals.

Other features include BNC jack input connectors, 19.5 VDC @ 4.5 mA sensor excitation power, and a 50 kHz upper frequency range. Output is transferred through the 3.5 mm stereo jack. When used in conjunction with a PC sound card or other data acquisition devices, the unit can record signals from a wide range of accelerometers or microphones that require constant current power. The device is ideal for use in portable measurement applications such as ride control, road testing, and cabin noise.
