Nivåbrytere

Nivåbrytere, also known as level switches, are devices used to detect the level of a substance within a tank, vessel, or container. They are crucial components in many industrial processes and automation systems, providing signals to indicate whether a certain level has been reached, exceeded, or fallen below a specific point. These signals can then be used to control pumps, valves, alarms, or other equipment to maintain optimal operating conditions or prevent overflows and dry runs.

There are various types of nivåbrytere, each employing different operating principles. Common technologies include float switches, which utilize a buoyant element that rises and falls with the liquid level to actuate a switch; conductivity probes, which detect the electrical conductivity of a substance to determine its presence; capacitive sensors, which measure changes in capacitance caused by the presence or absence of a material; and vibrating fork sensors, which detect the change in vibration frequency when the fork is immersed in a medium. The choice of nivåbryter depends on factors such as the type of substance being measured (liquid, solid, granular), its properties (viscosity, conductivity, temperature, pressure), and the required accuracy and reliability.

Nivåbrytere find widespread applications across numerous industries, including water treatment, chemical processing, food and beverage production, oil and gas, and pharmaceuticals. They are instrumental in tasks such as preventing tank overflows, ensuring minimum fluid levels for equipment operation, controlling filling and emptying processes, and monitoring the accumulation of solids in hoppers. Their reliable operation contributes significantly to process safety, efficiency, and product quality.
