Abstract

PURPOSE: To stablize the operation temp. of a high limit circuit, by means of detecting the temp. of a body to be controlled in temp. by a single detecting element, of allowing the temp. regulating circuit and the high limit circuit to be operated, and of varying the operation temp. of a temp. regulating circuit freely.
CONSTITUTION: A bridge circuit is formed by a resistor R1, a variable resistor Rv, a negative property temp. sensing element Th, and resistors R2, R3, and a NPN transistor TR is connected to the connection point of the resistor R1 and the variable resistor Rv, the emitter is connected to the connecting point of the variable resistor Rv and the temp. Sensing element Th, and the base is connected to the connected to the connection point of the resistors R2, R3. Said circuit is connected to a temp. regulating circuit Cr. And the output terminal of an operation amplifier OP1 is connected to a combustion device Ns. The output terminal of an operation amplifier OP2 of a high limit circuit CL is connected to a breaker Bs which allows the action of the whole circuit to be stopped. The values of the resistor R1WR7, the set resistor Rv, the temp. sensing element Th is regarded as r1Wr7, rv, rTh, r4, / r5<r5<r2/r3<r6/r7. When the temp. is low, it becomes to (r1+rv)/rTh<r2<r3, and the tran/istor is nonconductive, and when (r1+rv) rth<r4 <R5 is satisfed, the output of the amplifier OP1 of the regulating circit Cr is no present, and the combustion device Ns is actuated
