Abstract
Circuit device for an anemometer of the constant temperature and constant temperature difference type, comprising, in a known way, a bridge circuit, in which one branch of the bridge includes a resistor operating as a function of the temperature, acting as a transmitter of the measured value, and the opposite branch of the bridge includes a comparison resistor, and also comprising a control circuit which amplifies and integrates the voltage difference between the voltage on the transmitter G and the voltage on the comparison resistor P and makes this voltage difference, when it has been amplified and integrated, available as a control voltage to a power transistor to provide continuous balancing of the bridge, characterized in that the balancing of the bridge is achieved by selecting a nodal voltage for the formation of the control voltage for the power transistor TR as a reference voltage, amplifying the voltage on the opposite node with an amplifier which must consist of at least one impedance transformer, and sending this amplified voltage difference as the input voltage to an integrator. <IMAGE>
