How to create a pump control circuit to automatically

18-11-2013This diagram is for the circuit to empty a tank, using two normally open float switches and a two pole changeover relay. The bottom switch will be closed provided the liquid is above that switch point. The liquid rises until the top float switch closes and energises the relay. One set of relay contacts connects the pump to the supply and the other maintains the relay on-state, while the level

Solder Joints Electronics Notes

These solder joints may be completely open circuit, or they may be intermittent, high resistance or noisy. It is therefore essential that no dry solder joints are present in any electronics equipment. It is easy to identify dry joints. Unlike good solder joints that are shiny, dry joints have a dull or matt finish.

There is no trick to drilling through vias, provided you follow your fabricator's rules for minimum diameter, maximum aspect ratio (board thickness divided by hole diameter), and adjacency (minimum allowable distance from the edge of one via to the nearest adjacent via).

Resistors

In the circuit above, when the switch is open the MCU's input pin is connected through the resistor to 5V. When the switch closes, the input pin is connected directly to GND. The value of a pull-up resistor doesn't usually need to be anything specific.

Piping Layouts for Hydronic Heat

Thermostats open and close as necessary to meet the heating demand of the individual rooms. Because constant circulation is used, it is best to connect the boiler to the system as shown above. The boiler circulator operates only when the boiler fires. At other times, water flow in the main circuit bypasses the boiler, reducing off-cycle heat

Uranium Mining and Milling Wastes: An Introduction

MILLING OF THE ORE Ore mined in open pit or underground mines is crushed and leached in a uranium mill. A uranium mill is a chemical plant designed to extract uranium from ore. It is usually located near the mines to limit transportation. In the most cases, sulfuric acid is used as the leaching agent, but alkaline leaching is also used.
