PC420VP-10

RMS and peak velocity loop powered sensors PC420V series Wilcoxon’s PC420V series sensors provide a 4-20 mA output proportional to velocity 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. Key features Table 1: PC420Vx-yy model selection guide x (4-20 mA output type) yy (4-20 mA full scale) R = RMS output, velocity P = calculated peak output, velocity 05 = 0.5 ips (12.8 mm/sec) 10 = 1.0 ips (25.4 mm/sec) 20 = 2.0 ips (50.8 mm/sec) 30 = 3.0 ips (76.2 mm/sec) 50 = 5.0 ips (127 mm/sec) • True RMS or calculated peak output • Intrinsically safe certified and explosion-proof models available • Easily integrated into existing process control systems • Manufactured in an approved ISO 9001 facility Certifications Note: Due to continuous process improvement, specifications are subject to change without notice.
