Relative pressure-type level sensing transmitter Type 6810 pages

Level pressure sensing
transmitter type 681
Pressure range
0 ... 0.1 25 bar
The pressure transmitters of type 681 with piezoresistive
measuring elements have compensated, calibrated and amplified sensor signals which are available as standard voltage or
current outputs.
In the immersion-sensor version with a salt water and oilresistant connection cable they are specially suited for level
measurement, even in the presence of corrosive liquids.
The cable incorporates a tube for compensation of the ambient
pressure.
Manufactured from stainless steel, its welded construction
provides a watertight seal.
Mechanically protected diaphragm due
to special head design
Supplementary weight (option) improves
stabilization of sensor in turbulent media
Effective overload protection due to
chemically etched chip diaphragm and
specially designed glass gland
Compact construction using SMD
technology, enhances operational
reliability in the presence of shock and
vibration
Welded construction provides 100%
sealing against media
