Abstract
A wide range monitor apparatus for the output from a nuclear reactor has a logarithmic count rate measuring circuit and a Campbel measuring circuit corresponding to different neutron flux density ranges of the neutron flux output from a neutron detector. The apparatus monitors the nuclear reactor output as a single output which has a linearity with the neutron flux density over a wide range thereof. A logic circuit combines two comparison discrimination signals obtained by comparing low and high comparison voltages corresponding to the hysteresis width in an overlap region of the outputs from the two measuring circuits with detection output voltages from the two measuring circuits. One of the outputs from the two measuring circuits is selected in accordance with the logical level signal obtained by combining the two comparison discrimination signals by the logic circuit.
