- True peak output helps detect high-frequency impacts on reciprocating machines
- Intrinsically safe certified and explosion-proof models available
- Easily integrated into existing process control systems
- Manufactured in an approved ISO 9001 facility Certifications Wilcoxon’s PC420ATP series sensors provide 24/7 output of true peak acceleration, allowing for continuous trending of overall machine vibration in process control systems. True peak output is particularly useful in detecting loose parts on reciprocating machinery. The trend data alerts users to changing machine conditions and helps guide maintenance in prioritizing the need for service. 4-20 mA output type yy (4-20 mA full scale) ATP = True peak output, acceleration 05 = 5 g 10 = 10 g 20 = 20 g Table 1: PC420ATP-yy model selection guide
