An accurate technique of measurement of a transducer output by using a modified two core saturable reactor
چکیده انگلیسی

Saturable reactor or transductor used as a magnetic modulator or amplifier for the measurement of the small value DC output signal of a transducer may suffer from error due to the fact that a part of the current drawn from the transducer by the transductor unit is utilized to magnetize the core material. In this paper a modified two core saturable reactor circuit has been proposed to eliminate this error. This unit also minimizes some other errors like common mode error, material error, etc. Theory of operation and design of the circuit has been explained in this paper. The circuit has been tested by using a millivolt input signal as well as a thermocouple to measure temperature. The experimental results are presented in this paper. Linear static characteristic graphs have been observed.
