Huba Level Pressure Sensing Transmitter Type 681

Pressure range 0 ... 0.1 25 bar The pressure transmitters of type 681 with piezoresistive meas uring elements have compensated, calibrated and amplified sensor signals which are available as stand ard voltage or current outputs. In the immersion-sensor version with a salt water and oilresistant 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
