P702B

P702B is a general purpose power unit/amplifier. It is a portable unit specifically designed to furnish 2.4mA constant DC current (+27VDC) necessary to operate the internal charge amplifiers of Wilcoxon Sensing Technologies and similar piezoelectric transducers (accelerometers and velocity sensors). In addition the P702B provides signal conditioning, includes features such as selectable gain levels of 1, 10, 100, extremely low-noise, integration to yield velocity output, battery condition indication, and visible overload or open/shorted cable indication. This gives the test engineer broad capabilities for the accurate measurement and recording of vibration signals over a wide range of test situations. Also virtually any high impedance charge-type accelerometer can be operated with the P702B with the addition optional charge converter accessory, CC701. The P702B also has built-in ESD protection to guard against damage of the internal electronics.
