PC420 DPP 4-20 mA Vibration Sensors

Top exit, 4-20 mA (±5% @ 40 mils) proportional to displacement, peak to peak, 1/4-28 mounting hole (stud included), MIL-C-5015 connector


About the PC420 DPP

4-20 mA vibration sensors integrate easily with an existing PLC, DCS or SCADA system. The PC420DPP displacement sensor provides continuous trending of overall machine movement, and its peak to peak output gives a signal focused on machine balance. Measuring displacement vibration is useful for monitoring equipment health or controlling a process.


The 4-20 mA output of the PC420DPP series is proportional to displacement vibration. An output of 4 mA indicates no vibration present. A full-scale reading of 20 mA indicates that the maximum range of displacement is present

Key features PC420 DPP

  • Peak to peak derived from true RMS detection
  • Minimizes influence of blade pass and gear mesh frequency
  • Corrosion resistant
  • Hermetically sealed
  • ESD protection
  • Overload protection
