The level sensing transmitter of type 681 with piezoresistive measuring elements have compensated, adjusted and amplified sensor signals which are available as standard voltage or current outputs.
In the immersion-sensor version with a salt water and oil-resistant 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.
Medium : Fluides, aggressive fluides, potable water
Pressure range : 0 ... 0.1 – 25 bar
Output : 0 ... 5 V, 0 ... 10 V, 4 ... 20 mA
Accuracy : < 0.25% fs (< 0.05% fs on request)
Electrical connection : Cable in several lengths
