Wilcoxon’s side exit PCC423 sensors provide 4-20 mA output signal proportional to the overall vibration level. An output of 4 mA indicates no vibration; a level of 0 ips for velocity output models; a level of 0 g for acceleration output models. A full-scale reading of 20 mA indicates that the maximum range (RMS or peak) of vibration is present.

Features:

  • Acceleration or velocity output units
  • Enables continuous trending of machine vibration
  • True root-mean-square (RMS) or calculated peak output
  • Corrosion resistant
  • Hermetically sealed
  • ESD, overload and reverse wiring protection
The above description encapsulates the entire product series. Specifications for individual configurations may vary depending on the selection chosen.
