Abstract
PURPOSE: To secure the temperature display with the fixed temperature interval by giving the control to transistor Tr with the output of the temperature-sensitive element and then driving the light emitting diode via the output of the Tr.
CONSTITUTION: The temperature is converted into voltage signal VS by thermistor RS and resistance R0, and signal VS is applied to TrQ1WQ3 via R1WR3. And light emitting diodes D1WD3 plus current limit resistances R4WR6 are provided to the collectors of TrQ1WQ3. Here the value of R1WR3 are set so that TrQ1WQ3 may be turned on with voltage VS1WVS3 corresponding to temperatures T1WT3 to be displayed. Thus the temperature display is ensured with the fixed temperature interval.
