Product Overview
The Wilcoxon PCH420V series is a HART-enabled vibration transmitter designed for continuous asset monitoring. These velocity sensors feature 4-20 mA outputs with added digital communication capabilities via the HART protocol. This allows for user configuration of full-scale ranges and filter settings, reduced cabling requirements through single or multi-drop loop installations, and direct communication with HART-enabled DCS or PLCs. The PCH420V series enhances plant network connectivity, improving efficiency and simplifying machinery health decision-making. Hazardous area certified models are available for demanding environments.
