electric shock on water
Hi friends,
I have build a water tank controlling system, Using normal metallic probes as sensor. As for power supply i'm using normal Stepdown transformer 230v ac to 6-0-6 v and diodes and regulator with capacitors. Now what i'm afraid is, in INDIA due to voltage fluctuations the transformer burners out and there is current leakage between primary and secondary coil of tranformer which results in electric shock in water (due to immersed probes in water). Please tell me how can i build a isolation circuit and/or what more techniques can i use. i cannot change the type of sensor.
i've built the circuit using second part of this circuit

Thanks
With best regards,
Amit
