摘要：A signal conditioning circuit including power terminals adapted to be connectedto a direct current power source, sensor terminals adapted to receive a direct currentsignal from at least one electrical sensing device and output terminals adapted to beconnected to an electrical resistance. The conditioning circuit includes an inverter
connected to the power terminals for generating an output signal of opposite polarity tothe signal received at the power terminals. An adjustment mechanism is connected to theoutput terminals for receiving the inverter output signal and adjusting the magnitude ofthe signal received at the sensor terminals to a desired level. In a second mode ofoperation, the circuit includes a second set of sensor terminals and the adjustmentmechanism operates to deliver an output signal proportional to the difference betweenthe signals received at both the first and second sensor terminals.
