Pressure level transmitter
Type 681 Relative pressure-type level sensing transmitter
Relative pressure-type level sensing transmitter Type 681
0 … 0.1 – 25 bar
The pressure transmitters of type 681 with piezoresistive measuring elements have compensated, adjusted and amplified sensor signals which are available as standard voltage or current outputs.
More Details
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.

Type 700 OEM Level sensing absolute pressure transmitter
OEM Level sensing absolute pressure transmitter Type 700
0.8 … 1.4 – 10 bar
The OEM level sensing pressure transmitters type 700 are used for the level measurement in various media.
More Details
The level measurement is made with an absolute pressure measuring cell. Therefore the pressure (barometrical) which influences the media must be specified. A second transmitter with a measuring range of 0.8 … 1.4 bar may be used. Depending on the application the information about barometrical pressure is available on the internet.
