Description
The Wilcoxon Sensing Technologies PCH420V series vibration sensors are velocity transmitters with 4-20mA outputs and the added capability of digital communications using HART protocol. The HART functionality allows user configuration of the sensors, enables multi-drop cable installations, and allows the sensor to communicate directly with a HART-enabled DCS or PLC. The PCH420V can be configured by the user for a number of different full-scale ranges and filter settings and can be connected to existing plant infrastructure.
The PCH420V’s case isolated, hermetically sealed design has a 1/4-28 tapped hole for mounting and either a 4-pin M12 or 2-pin MIL-C-2015 connector. The PCH420V is manufactured in an approved ISO 9001 facility.
