The Columbia Model 5421 Single-Channel Power Supply provides a convenient unity gain interface between any Columbia 8000 or 900 Series Integrated Piezoelectric Accelerometer and a variety of display or analyzing type instruments. This supply provides a 4.0 mA DC constant current to the pre-amplification circuitry within the transducer thus eliminating the need for a complex and costly charge amplifier. This current source will permit the use of any length output cable up to 500 feet long.<\/p>\n
