The instrument should be robust against overload and have good insulation. The measuring mechanism's moving part always lies vertically or horizontally. The part of the transformer mechanism always lies vertically or horizontally and is secured on an axis or on stretchers or suspended. The movable part of the instrument that is secured on an axis plays a crucial role in the support of the support pins that reduce friction. The support pins press. The support pins press. The support stones. The support stones. The plug. The agate. The corundum. Or bronze. Or bronze. The axis of the instrument is usually made of stainless steel or stainless steel. In the working moment, a spiral spring is created. The instrument creates a spiral spring. The opposing moment is created by a spiral spring made of bronze. The bronze is made of bronze. One end is attached to the axis of the movable part of the instrument, and the other end is attached to one of the components of the casing. A special cylinder is used to create a moment that opposes the rotating moment. When the axis is rotated, the spiral spring is tightened or loosened, and consequently the pointer moves. To eliminate the oscillation of the pointer, dampers of magnetic or air type are installed. Magnetic dampers consist of stationary cylindrical magnets. Magnetic dampers consist of a group of stationary cylindrical magnets on the axis of the movable part of the instrument that are fixed to an aluminum plate. When the plate rotates, it intersects the magnetic field. And an electrical signal is induced in the plate. The plate intersects the magnetic field and an electrical signal is induced in the plate. The signal is proportional to the angular speed of rotation of the axis. Therefore, a current is generated in the plate, which interacts with the magnetic field, resulting in a moment. The moment is always directed opposite to the direction of rotation of the axis. This is where you can see. The magnets are round? Or not very round? And the pointer with an aluminum plate. Below it are magnets. Then we will watch the video. When the pointer moves, the TDS is generated, which creates a force that stops it. More thoroughly, we will study. The opposite direction of rotation of the axis. To ensure that the center of gravity of the movable part of the instrument coincides with the axis of rotation on special holders, which are rigidly connected to the pointer, weight supports with internal grooves are installed. At the bottom, there is a pointer, and
