charge amplifier / instrumentation / conditioning / transducer
2634 Bruel and Kjaer



  • Type:


  • Secondary function:

    instrumentation, conditioning

  • Other characteristics:

    transducer, for vibration measurement, compact


Designed for vibration measurements in industrial environments

Type 2634 is a compact, two-stage charge amplifier which conditions the output signal from piezoelectric transducers before onward transmission to the measuring/analysis instrumentation. It is intended mainly for vibration measurements in industrial environments where its sturdy construction will permit it to be sited in conditions alien to normal electronic instrumentation.
