Abstract

PURPOSE: To prevent the malfunctioning by varying the control voltage applied on the base terminal of the switching element of the alarming element employing a thermistor.
CONSTITUTION: As the liquid level lowers with the consumption of oil in the oil tank, the liquid level detection switch 18 is closed and the thermistor is energized for a fixed time. This causes the thermistor to generate heat by itself increasing the resistance thereof. As the resistance of the thermistor 20 increases, the control voltage applied on the base terminal of te switching element 14 rises, energizing the switching element 14. Consequently, the warning lamp 12 comes on.
