Dual Level Liquid Sensor
This level liquid sensor electronic circuit diagram is based on a common Ca3410 operational amplifier IC . This level liquid sensor electronic circuit use two plates sensors ( two probes ) , one for the high level an one for low level .
Dual Level Liquid Sensor Circuit Diagram
If the level of the liquid is not in the adjusted range the LED will glow . The circuit require just a CA3410 operational amplifier and other few common components . This dual liquid level sensor require a 15 volt DC power supply circuit .

Dual Tracking regulator circuit
A IC MAX634 inverting regulator is combined with a IC MAX630 to provide a dual tracking approximately 15 Volt output from a 12 Volt DC battery. The reference for the - 15 Volt output is derived from the positive output via R3 and R4. Both regulators are set to maximize output power at low battery voltages by reducing the oscillator frequency , via LBR, when V Batt falls to 8,5 volt.
Technical instruction :
Max. Input voltage : 13 Volt / N/a mA
Max. Output voltage :-15 Volt , + 15 volt / 45 mA
