Certifications

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.

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.
