Abstract

PURPOSE: To detect the presence of wind with no adjustment by using a simple circuit by providing a heater resistance near to one of two thick film thermisters of the same rating.
CONSTITUTION: A heater resistance r5 near to thermister Th6 of thick film thermisters Th5, Th6 of the same rating is disposed, and the temperature of the thermister Th5 is raised. Then when wind is not present, a variable resistor Vr3 is adjusted to turn the transistor Tr3 on. When there exists wind, the transistors Tr3, Tr4 are turned off and the signal indicating whether wind exists or not is output from the output terminal C.
