ADOPTING OF SENSORS WITH AMORPHOUS RESISTIVE LAYERS IN ELECTRICAL MEASURING OF SPEED OF FLUIDS IN SHIPS

New resistive elements, formed upon electro insulated plate of vacuum thick ceramics by magnetron sputtering or screenprinting of amorphous resistive layers are studied. The elements possess a relay-type strong negative temperature dependence of resistivity. The new elements are adopted as sensors in standard bridge circuits for measuring of speed of fluids. Prototypes of sensors with various compositions of amorphous metal layers are analyzed and compared. The new elements show better sensitivity compared to a standard sensors.
