The Model 681 level sensing transmitter with piezoresistive measuring element has a compensated, adjusted and amplified sensor signal available as a standard voltage or current output. In versions of immersion sensors with saltwater - and oil-resistant connection cables, they are particularly suitable for level measurement, even in the presence of corrosive liquids.

The cable contains tubes to compensate for ambient pressure.

Made of stainless steel, its welded construction provides a waterproof seal.
