Relative and absolute pressuretransmitter type 680
Pressure range
0 ... 0.1 1000 bar

The pressure transmitters of type 680 with piezoresistive
measuring elements have compensated, calibrated and amplified sensor signals which are available as standard voltage orcurrent outputs.
The transmitter housing is available with various pressure andelectrical connections.
Manufactured from stainless steel, its welded construction
provides a watertight seal. With its sophisticated building block
system, individual designs to meet specificapplications are possible.

Effective overload protection due tochemically eteched chip diaphragm andspecially designed glass gland
Fast and affordable customer specificsolutions due to building block system,
even for small quantities
Compact construction with SMD technology enhances operational reliability inthe presence of shock and vibration
Welded construction provides 100%
sealing against media
