The pressure transmitters of Type 681 with piezoresistive measuring elements have compensated, calibrated, and amplified sensor signals, which are provided as standardized voltage or current outputs. In the version as a submersible probe with saltwater- and oil-resistant connection cable, they are particularly suitable for level measurement of aggressive liquids. For ambient pressure compensation, a tube is routed through the cable. All metal parts made of stainless steel are hermetically welded.

 

- Mechanically protected membrane through special head design

- 100 % sealed against medium, as fully welded

- Better stabilization of the sensor in turbulent media through additional weight (option)

- High overload safety due to chemically etched chip membrane and special design of the glass feedthrough

- Compact design in SMD technology increases operational safety during shock and vibrations
