Absolute 0 to 16 bar
EDITION 12/2004
HUBA-REGISTERED TRADE MARK Huba Control
FOR FINE PRESSURE AND FLOW MEASUREMENT
Technical overview
The pressure transmitter of type series 691 with unique and for the last 10 years used in millions of applications ceramic technology, features calibrated and amplified sensor signals which are available as standardized voltage or current out-puts.
Various application-specific pressure and electri-cal connections can be provided.
The distinct advantages
•Very low temperature sensitivity •High resistance to extreme temperatures •No mechanical aging •No mechanical creepage
•Individual applications due to modular system
