Industrial Style Back Pressure Controller
Bronkhorst® models P-502CI through P-532CI Electonic Pressure Transducers (EPTs) can be combined with control valves for precise measurement and control of pressure ranges between 2…100 mbar and 8…400 bar absolute or gauge. The standard direct acting valves (F-001AI/F-011AI) are normally closed, have a pressure capability up to 100 bar and are available for Kv-values up to 6.6 x 10-6. Normally opened valves can also be supplied. For pressure control in combination with high flow rates, Bronkhorst has pilot operated valves models F-002AI and F-003AI/F-003BI with Kv-values up to 6.0 ! The so-called Vary-P valve F-033 that can cope with 400 bar delta-P. And finally, our bellows valve F-004 can be used for applications with very low differential pressure.
All combinations of IN-PRESS pressure meters with control valves are of rugged design (IP65) for use in industrial environments or even Zone 2 hazardous areas, with optional ATEX Cat. 3 approval.
IN-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 DeviceNet™, PROFIBUS DP, Modbus or FLOW-BUS protocols.
Note: The measuring cell of the pressure sensore is separated from the external pressure by a thin, sensitive stainless steel diaphragm, and the sealed off cavity between diaphragm and cell is filled with oil. Since the standard oil filling is flammable, Bronkhorst advises to take precautions when oxygen or any other explosive fluid is used.
