A device that keeps physical quantities such as frequency, speed, power, pressure, voltage and current stable to a certain extent and is able to change them in order to keep stable. Today modern methods are used during the production of food, clothes and other materials used in daily life. During the production with for example various types of boilers, furnaces, dryers, stoves, sterilizers and other similar equipment, some special conditions must be met. These are temperature, pressure, moisture, time, fluid level, flow and speed of moving parts. In order to uphold these conditions various types of automatic regulators are used in the necessary areas. These either operate on their own, with air, with steam or with electricity. Depending on the regulation type or need the regulators can be simple or complicated. A regulator basically consists of a finder element, a sender organ and a servomotor. The finder element measures the regulated size. The sender organ regulates the changes in the regulated size depending on the difference between the size and the size that will keep it stable. The servomotor supplies the necessary power for the sender organ in order for it to change the difference.
