Eckardt water level controller     Summary    244LD intelligent displacer level (interface) level transmitter is designed based on Archimedes Buoyancy Principle. It can be used for measuring liquid level, interface and density.  This Transmitter is available for any dangerous application. 244LD intelligent displacer level (interface) transmitter is manufactured by Dandong Top Electronics Instrument (Group) Co. Ltd and FOXBORO, The transmitting head and other important parts are original products supplied by FOXBORO, the finished products are as per the original factory standard (FOXBORO).     Principle   The buoyancy of displacer 4 is transmitted to the sensor 3 via lever 1 and the torque tube 2. In measuring range, the voltage is proportional to the buoyancy, and as the input signal is transmitted to the electronic amplifier. Through the electronic amplifier, voltage is converted to 4-20 mA two-wires output signal. In the two-wires system mode, amplifier is powered by the signal current circuit.     Parameter
