Abstract: An examination and test system for nuclear-grade control valve is provided and includes a hermetic first chamber, a base, a guide unit, a winder, a steel cable, and a length measurement device. The hermetic first chamber includes a second chamber for accommodating a control valve. The base is disposed outside the hermetic first chamber. The guide unit is disposed on at least one of the control valve and the base. The winder and the length measurement device are disposed on the base. The steel cable connects with a valve rod of the control valve and extends out of the hermetic first chamber to connect with the winder. The steel cable is wound on the guide unit, wound up by the winder, and thus rendered taut at any time. The length measurement device has a measurement element coupled to the steel cable and displays the displacement of the measurement element.

Abstract: An examination and test system for nuclear-grade control valve is provided and includes a hermetically sealed chamber, a base, a guide unit, a winder, a steel cable, and a length measurement device. The hermetically sealed chamber includes a chamber for accommodating a control valve. The base is disposed outside the hermetically sealed chamber. The guide unit is disposed on at least one of the control valve and the base. The winder and the length measurement device are disposed on the base.

Abstract: A liquid-level gauge testing device includes a table, a height control unit, an indicator unit, and a liquid container. The height control unit includes a displacement mechanism mounted on the table and a carrier coupled with the displacement mechanism to move upward and downward. The indicator unit is mounted on the table and coupled with the carrier. The liquid container is arranged below the carrier. By providing the table, the height control unit, the indicator unit, the container and other relevant components, the liquid-level gauge testing device is able to provide increased testing accuracy with simplified testing procedures and reduced testing time. A liquid-level gauge testing method is also disclosed.

Abstract: A concentrator photovoltaic measuring device includes a platform, an enclosing mask, a converging lens, a concentration unit, a first temperature regulation unit, a second temperature regulation unit, a temperature detection unit, a data transmission unit, and an electricity transmission unit. With its temperature regulation function, the concentrator photovoltaic measuring device simulates the effect of seasonal temperature variation on the energy conversion efficiency of a solar cell, so as to be effective in measuring the energy conversion efficiency of the solar cell in real environment and environment having a specific variable. Also, the concentrator photovoltaic measuring device accommodates a single solar cell, so as to be capable of measuring the single solar cell.
