Wilcoxon Research PC420V series RMS and peak velocity Loop Powered Sensors (LPS™) Output, 4-20 mA Full scale, 20 mA, ± 5% �� Frequency response: ± 10% �� ± 3 dB �� Repeatability �� Transverse sensitivity, max. �� True RMS or calculated peak output Corrosion resistant Hermetic seal ESD protection Overload protection Reverse wiring protection • Choice of output: RMS or peak, permits you to choose the sensor that best fits your industrial requirements • Provides continuous trending of overall machine vibration • Can help guide maintenance in prioritizing need for service • Helps notify of impending equipment failure The 4-20 mA output of the PC420V series is proportional to velocity vibration. An output of 4 mA indicates a level of 0 ips or no vibration present. A full-scale reading of 20 mA indicates that the maximum range (RMS or peak) of vibration is present. Power requirements (2 wire loop power): Voltage at PC420 series sensor terminals �� >12 VDC, 30 VDC max Loop resistance at 24 VDC, maximum �� 700 Ω Turn on time, 4-20 mA loop �� 30 seconds Grounding �� case isolated, internally shielded Operating temperature range1 �� –40 to 105° C Vibration limit �� 250 g peak � Shock limit �� 2,500 g peak Sealing �� hermet
