Abstract

PURPOSE:To keep a discrimination difference detection characteristic for a substance to be discriminated to be constant, by keeping the temperatures of a light-emitting body and a light-receiving body in a certain degree or above in a sensor discriminating said substance on the basis of the degree of transmission of light. CONSTITUTION:A hole 6 piercing through the opposite sides of a square sensor block 5 having a V-shaped groove portion 4 in the top part is provided at a position at which it pierces through the bottom of said groove portion 4, and a light-emitting body 1 and a light-receiving body 2 communicating with a discriminating device respectively are disposed opposite to each other so that the groove portion 4 is located between them. A thermostat 7 sensing the temperature of the block 5 and performing a temperature control is provided in the part of the block 5 on the lower side of the groove portion 4, and moreover a pair of electric heating bodies 3 are provided in the transverse direction on the lower side of said thermostat 7. The electric heating bodies 3 communicate with a power source 8 through the intermediary of the thermostat 7.
