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.
