TRANSMITTER-ALARM OF PARAMETRIC AND SIGNAL INFORMATION ON LEVEL OF LIQUID AND SYSTEM MEASURING LEVEL OF LIQUID IN CLOSED VESSEL |
摘要 |
distant measurement and level control. SUBSTANCE: transmitter-alarm of parametric and signal information on level of liquid has frame with electric connector, potentiometer and float. Non-magnetic directing tube housing set of potentiometers made in the form of two printed circuit boards with hermetically sealed reed relays and resistors installed discretely and alternately is attached to frame by means of electric connector. Float is mounted for movement along directing tube and includes two bar magnets located in parallel to level of liquid. System measuring level of liquid in closed vessel incorporates transmitter-alarm of parametric and signal information on level of liquid installed in closed vessel and interrelated to key and auxiliary information users. Key and auxiliary information users are interrelated to corresponding printed circuit board of transmitter-alarm. EFFECT: enhanced functional reliability of transmitter-alarm. 2 cl, 4 dwg
