measurement technology. SUBSTANCE: invention an find use in electronic balances, dynamometers, measurement systems and other devices incorporating force cell. Intellectual force cell includes case, piezoplates, temperature-sensitive element, controller with converters and communication cable. Case has space formed by three holes and houses springy beam carrying piezoplates. Controller is attached to side face of case and is connected to electrodes of piezoplates and temperature-sensitive element anchored in space. Controller incorporates initiation circuits, adder, detector of difference frequency, master oscillator, microcontroller, converter of levels and communication port to which cable is linked. Processing of signals coming from piezoplates and temperature-sensitive element, computation and output of information on value of measured force in digital code are carried out in built-in microcontroller by means of soft and hardware methods. EFFECT: increased accuracy, simplified operation and expanded application field. 5 dwg
