The intelligent GKYWG-60 servo level gauge is a highly intelligent instrument based on a microprocessor, which combines * servo measurement technology with imported servo motor components to greatly improve the measurement accuracy of liquid level. The intelligent servo liquid (boundary) level meter can perform routine and accurate measurement and signal transmission of liquid level and boundary position of the measured medium, and also has functions such as temperature transmission. It meets the requirements of storage tank capacity management, loss control, cost saving, and safe operation, improves data communication function, enhances data stability, has a serial data communication RS485 interface, and outputs corresponding 4-20mA analog signal output.
1. Working principle of GKYWG-60 servo level gauge: Based on the principle of buoyancy balance, the servo level gauge is driven by a micro servo motor to a small volume float, which can accurately measure parameters such as liquid level. When the liquid level gauge is working, the gravity of the float acting on the fine steel wire generates a torque on the magnet of the outer wheel hub, causing a change in magnetic flux. The change in magnetic flux between wheel hub components causes a change in the output voltage signal of the electromagnetic sensor of the inner magnet. Compare its voltage value with the reference voltage stored in the CPU. When the position of the float is balanced, the difference is zero. When the liquid level of the measured medium changes, the buoyancy of the float changes. The result is that the magnetic coupling force is greatly altered, causing a change in the output voltage of the Hall element with temperature compensation. The difference between this voltage value and the reference voltage in the CPU drives the servo motor to rotate, adjusting the float to move up and down to reach the equilibrium point again. The entire system forms a closed-loop feedback loop with an accuracy of ± 0.7mm, and its own hanging compensation function can compensate for changes in wire tension caused by the adhesion of the measured medium to the wire or float.
2. Product Overview: GKYWG-60 servo level gauge is a high-precision measuring instrument developed by Hebei Guangke Measurement and Control Equipment Co., Ltd. in combination with foreign products, which uses microelectronics technology and servo motor drive technology to measure the liquid level boundary. It has very high safety and reliability. The GKYWG-60 servo level gauge is designed to be explosion-proof and can be widely used in various flammable and explosive places. It is an ideal choice for tank level measurement in fields such as petroleum and petrochemical, power, medicine, and food.
