Amphenol Wilcoxon PCH420 Vibration Sensors

Amphenol Wilcoxon PCH420 Vibration Sensors are velocity transmitters with 4-20mA outputs and enabled with the Highway Addressable Remote Transducer (HART) communication protocol. This protocol enables multi-drop cable installations and allows the sensor to communicate directly with a HART-enabled distributed control system (DCS) or programmable logic controller (PLC). Amphenol Wilcoxon PCH420 Vibration Sensors can be user-configured and offer continuous asset monitoring with remote configuration and diagnostics. These sensors are manufactured in an approved ISO 9001 facility.
