Huba pressure level transmitter

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.  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 Technical overview 1) Pressure ranges Relative     0 ... 25 bar Absolute  

The level sensing pressure transmitter Type 712 is manufactured using a relative and absolute pressure measuring cell with an adjusted and amplified sensor signal and is available with various cable lengths from 2 to 30 meters. The Type 712 offers EX protection as well as versions with integrated temperature measurement.   In addition to voltage and current outputs the Type 712 is available with ratiometric outputs.  suitable for drinking water intrinsically safe execution with voltage-  and current output with integrated temperature  measurement suitable for fitting in 1-inch pipe Technical overview Pressure range Relative     0.0 ... 0.3  2.5 bar Absolute     0.8 ... 1.4  3.0 bar Operating conditions 1)      Fuel oil, ultra-light   SN 181 160-2 1)      Fuel oil, heavy   SN 181 160-2 1) Medium     Diesel oil 1)      Benzine      Water     Medium and ambient -20 ... +80 ¨¤ Temperature     Storage -40 ... +80 ¨¤ Overload  &nbs
