Abstract
PURPOSE: To enable to detect the rate of change in temperature in air flow and the temperature of air, by at least one set of the temperature sensing substance of which resistance value is changed at a given temperature, on the way of the differential distribution type sensing wire.
CONSTITUTION: One of more of the normally closed type thermostats 3 which break contact at a given temperature, on the way of sensing wire I connecting a number of thermocouples 1 with the copper wire 2, are inserted. If the rate of temperature rise of air flow is more than a given value, the electromotive force of the thermocouples is amplified 10 through the open wire detection circuit 8 and the filter circuit 9, and is this value exceeds a given value, the threshold value detection circuit 11 produces an output to activate the thermo switch 3. The voltage of the power supply of the circuit 8 is inputted to the amplifier 10 with voltage division and this output activates the circuits 11 and 12 as the same as mentioned above. Thus, the rate of temperature rise of air flow and the temperature of air flow exceed a given value, they can be detected.
