Abstract
An electromagnetically force-compensating force-measuring apparatus () that includes a force dependent support coil () and an integrating analog/digital converter (') that converts the coil current (I) into a digital output signal. A current/voltage converter () is connected downstream of the support coil (), the output of the current/voltage converter being connected to a measurement voltage input () of the analog/digital converter (′) and to the input of a voltage amplifier (). The resistance value of a first heating resistor (R) is equal to the resistance value of the support coil (), the resistance value of a second heating resistor (R) is equal to the conversion factor (R) of the current/voltage converter () and the gain factor of a voltage amplifier () is equal to the ratio of the resistance value of the first heating resistor to the resistance value of the second heating resistor.
