Pressure transmitter 680

The pressure transmitters of Type 680 with piezoresistive measuring elements have compensated, calibrated, and amplified sensor signals, which are output as standardized voltage or current outputs. The housing with the electronics can be combined by the manufacturer with various pressure and electrical connections. All metal parts made of stainless steel are hermetically welded. This sophisticated modular system allows for individual design for your application needs.

High overload safety due to chemically etched chip membrane and special design of the glass feedthrough
Fast and cost-effective customer solutions through modular system even for small series
Compact design in SMD technology increases operational safety during shock and vibrations
100 % sealed against medium, as fully welded
