The IN-PRESS series digital electronic pressure transducers and controllers for gases and liquids are equipped with a rugged, 'industrial style' (IP65) pc-board housing for use in industrial environments. The instruments have a well-proven compact thru-flow design and include a diaphragm type piezo-resistive pressure sensor for pressure measurement\/control from the lowest ranges (2 ... 100 mbar absolute or gauge) up to the highest ranges (8 ... 400 bar absolute or gauge). The pc-board of an IN-PRESS pressure meter features integrated, adaptable PID control for fast and smooth control of any electronically driven valve. The standard direct acting valve (F-001AI\/F-011AI) is normally closed, has a pressure capability up to 100 bar and is available for Kv-values up to 6.6 x 10-6. Normally opened valves can also be supplied. There is also a pilot operated valve for high flow rates (Kv-max 6.0 !!!), the so-called Vary-P valve that can cope with 400 bar delta-P and a bellows valve for applications with very low differential pressure. All these control valves are available with IP65 protected coils.","\"Multibus\" Digital Pressure Meters\/Controllers","Bronkhorst High-Tech developed their digital instruments according to the flexible \"multibus\" concept, due to which the instruments can be equipped with on-board interface board with DeviceNetTM, Profibus-DP®, Modbus or FLOW-BUS protocol.
