IN-PRESS Industrial style Pressure Meters / Controllers

Weatherproof (IP65) and Rugged Design

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:

  • lowest ranges 2 ... 100 mbar absolute or 0,7 ... 35 mbar gauge up to
  • 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 developed their digital instruments according to the flexible "multibus" concept, due to which the instruments can be equipped with on-board interface board with DeviceNet, PROFIBUS DP, PROFINET, Modbus or FLOW-BUS protocol. More information about digital "multibus" communication.

The pressure controller performs with high accuracy and repeatability and should be specified for "forward pressure control" (P-600 series for control of downstream pressure "P2"), "backward pressure control" (P-700 series for control of the upstream pressure "P1") or "process pressure control" (P-800 series, a dual-valve design for pressure control inside closed compartments or systems).
