The Level Alarm Circuit Demonstrator consists of three level Electrodes. One for Upper Level and the other for Lower Level Detection. The third acts as Reference Electrode. The height of upper and lower level detection electrodes are adjustable. Detection of level is by electronics circuit capable of providing a binary output. When the water is below lower level detection electrode, the water pump switches ON, and an audio alarm is initiated. When the water level reaches upper level the pump is switched OFF. A mechanical stopcock is used to drain the water from the tank. This simulates fall in water level. Specifications: - Two level, adjustable electrodes.
- 1 Lt. water tank and a sump.
- 230 V AC operated pump, operated by a relay.
- Piezo electric alarm.
- The system has built-in power supply suitable for the above.
- Stopcock arrangement to drain water from the tank to sump.
