Dwyer Photohelic Pressure Gauge & Switch. 3-in-One Indicating Gage, Lo-limit and Hi-Limit Control. Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic design. The Photohelic measures and controls positive, negative or differential pressures of air and compatible gases.
The diagram above illustrates the operation of a basic photovoltaic cell, also called a solar cell. Solar cells are made of the same kinds of semiconductor materials, such as silicon, used in the microelectronics industry.For solar cells, a thin semiconductor wafer is specially treated to form an electric field, positive on one side and negative on the other.he diagram above illustrates the operation of a basic photovoltaic cell, also called a solar cell.
