This demonstrator is an ON-OFF control interface instrument to Microprocessor trainer. It is intended to demonstrate how a Microprocessor controls the water level in a tank. This instrument consists of a 2-4 liter water tank. The ON and OFF of the pump is controlled by a 230V AC operated relay under program control. Two sensing electrodes monitor a bi-level i.e. lower level and upper level. The height of these electrodes is adjustable within the tank's limit. Control program identifies the status of these electrodes and switches ON or OFF the pump. A manual drain cock drains water from the tank, by turning the wheel valve. This is required to simulate the fall in water level. Specifications: - Adjustable Bi-level sensing electrode.
- 2-4 liter water tank, with drain facility.
- Relay operated special purpose water pump
- Necessary couplings and tubes.
- Built-in power supplies.
Note: Microprocessor trainer MPT-85 or IBM PC add-on card model IBR-1 is required. |
