Digital Electronic Back Pressure Controllers
Bronkhorst® model P-702C Digital Pressure Controllers (Electronic Pressure Controllers - EPCs) are suited for precise measurement and control of upstream pressure ranges between 20…100 mbar and 12,8…64 bar absolute or between 7...35 mbar and 12,8...64 bar gauge. This Digital Pressure Controller has a well-proven compact thru-flow design and includes a diaphragm type piezo-resistive pressure sensor, a microprocessor based pc-board with signal and fieldbus conversion and a compact, fast acting control valve.
EL-PRESS series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The main digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output the instruments also offer analog I/O. As an option, an on-board interface can be mounted to provide CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocols.
