Hydrostatic level transmitter 681
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
