IN-PRESS

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
  
  

Features

• Thru-flow design
  
• Compact arrangement
  
• Stable control, even at varying process volumes
  
• High pressure capability up to 400 bar
  
• Classification IP65
  
• Option: ATEX-approval for Cat. 3, Zone 2
  
• Option: KCs certificate (Protection Ex nA IIC T4)

Integrated, adaptable PID control for fast and smooth control

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" (control of downstream pressure "P2"), "backward pressure control" (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).
