  • True RMS or calculated peak output
  • Easily integrated into existing process control systems
  • Intrinsically safe certified and explosion-proof models available
  • True peak output available
  • Manufactured in an approved ISO 9001 facility Certifications Wilcoxon’s PC420A series sensors provide a 4-20 mA output proportional to vibration, allowing for continuous trending of overall machine vibration. This trend data alerts users to changing machine conditions and helps guide maintenance in prioritizing the need for service. The choice of RMS or peak output allows you to choose the sensor that best fits your requirements. x (4-20 mA output type) yy (4-20 mA full scale) R = RMS output, acceleration P = calculated peak output, acceleration 05 = 5 g 10 = 10 g 20 = 20 g 50 = 50 g Table 1: PC420Ax-yy model selection guide Note: True peak output is available on PC420ATP series models.
