HART-enabled vibration transmitter PCH420V series The PCH420V series sensors are velocity transmitters with 4-20 mA 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 benefits are a sensor that can be configured by the user for a number of different full-scale ranges and filter settings, a reduction in the required cabling, and simple connection to existing plant infrastructure. Digital sensors allow improved connectivity into plant networks, improving efficiency and simplifying decision-making about machinery health. Device variables: Key features PV - Vibration band 1 SV - Vibration band 2 TV - Vibration band 3 4-20 mA + HART 7.0 output Three user-configurable bands Single or multi-drop loop installation Hazardous area certified models available Model Description 4-20 mA + HART velocity sensor with Remote configuration and PCH420V-R6(-HZ) 2 pin MIL-C-5015 connector diagnostics 4-20 mA + HART velocity sensor with PCH420V-M12(-HZ) 4 pin M12 connector Connector options: 2 pin Note: Model numbers ending in -HZ are hazardous area certified sensors. MIL-C-5015 (-R6 models) or M12 (-M12 models) Certifications Continuous asset monitoring -HZ models only: Manufactured in an II 3 G Ex nA nC IIC T4 Gc approved ISO 9001 facility Class I, Div 2 Ta = -40C to +105C Groups A, B, C, D (all models) Class I, Zone 2 AEx/Ex nA nC IIC T4 Tamb: -40C to +105C The cable installed must be suitable for the installation temperature and the voltage of any intermingled circuits. Connected cable must be of a type suitable for Zone 2 Hazardous Locations. The connected cable and connector must provide a minimum ingress protection level of IP54, when assessed according to EN 60079-0 and EN 60079-15. Unused connector must be fitted with an appropriately rated blanking cover . The connection must be made in a manner that cannot be separated without the use of a tool. Where the installation requires that the Accelerometer enclosure be grounded, this is to be done using a metal mounting stud as described in document 13327-01, 13334-01, 13335-01 or 13336-01.
