Abstract

PURPOSE: To operate a controlling system to safety side when a temperature measuring resistor is disconnected and simplify the configuration of the temperature converter circuit by fully fluctuating the output of an arithmetic unit to plus side by employing predetermined current from a constant current source.
CONSTITUTION: When the current supplying wire A1 of a temperature measuring resistor 1 is disconnected, an electric current i from a current source 2 is flown through a diode D1, resistors Rt, R6 to fully fluctuate the output e0 of the arithmetic unit 3 to plus side by the relationship between the inputs e1, e2, e3 of the unit 3. When the voltage detecting wire B1 is disconnected, the current i is flown through the resistors Rt, R6 to fully fluctuate the output e0 to plus side by the relationship between the voltages e1, e2, e3. When the voltage detecting wire B2 is disconnected, the current i is flown through the resistors Rt, R6, the output e0 is fully fluctuated to plus side by the relationship between the voltages e1, e2, e3. When the current supplying wire A2 is further disconnected, the current i is flown through the resistors Rt, R2, the diode D2 and the resistor R6 to fully fluctuate the output e0 to plus side by the relationship between the voltages e1, e2, e3.
