Abstract

PURPOSE:To display separately the liquid level and specific gravity of electrolyte by one circuit by connecting a liquid level sensor and a specific gravity sensor, provided inside a storage battery, to the terminal of the storage battery through two transistors, a luminous diode and a resistor. CONSTITUTION:The inside of the storage battery 1 is provided with the liquid level sensor 4 in a conducting state when contacting with the electrolyte 2 but in nonconducting state when not contacting with the electrolyte 2 and the specific gravity sensor 5 in conducting state when the specific gravity of the electrolyte 2 exceeds a fixed value but in nonconducting state when the specific gravity is below a fixed valve. And, the sensor 4 and the sensor 5 are connected through the resistors 6-8 to the terminal 3 of the storage battery, the emitter of the first transistor 9 is connected to the sensor 4, a base is to the sensor 5, and a collector is to the terminal 3 of the storage battery through the luminous diode 11 and the resistor 8. Furthermore, the emitter of the second transistor 10 is connected to the sensor 5, the base is to the sensor 4, and the collector is to the terminal 3 of the storage battery through the luminous diode 12 and the resistor 8.
