。[Scope of Claim for Utility Model Registration] A measurement signal detected by a sensor is converted into a digital signal by a signal converter and taken in, and a predetermined digital calculation is performed by a calculation unit according to the range set by a range setting unit. In a transmitter that converts the signal into an analog signal using a D/A converter and outputs the signal, a zero point transition signal generating means generates an analog zero point transition signal based on the measurement range set by the range setting section; a signal amplification circuit that receives the measurement signal detected by the sensor and the zero point transition signal and differentially amplifies both signals; A transmitter characterized in that it is designed to be
