REMOTE MEASURING APPARATUS BY USING CONSTANT VOLTAGE FEEDBACK

摘要

According to an embodiment of the present invention, provided is a remote measuring device using constant voltage feedback comprises: a first feedback operational amplifier which connects one end of reference power with a reference voltage to a first input end and connects one end of a measuring device to a second input end; and a second feedback operational amplifier which connects the other end of the reference power to the first input end and connects the other end of the measuring device to the second input end. The output end of the first feedback operational amplifier is connected to a first outside connection terminal which is connected to the one end of the measuring device. The output end of the second feedback operational amplifier is connected to a second outside connection terminal which is connected to the other end of the measuring device.
