IN-PRESS
Industrial style Digital Pressure Meters / Controllers
General
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 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 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. More
