Ultrasonic level switches

Ultrasonic level switches offer reliable measurement and minimal maintenance in a variety of industrial applications.

As ultrasonic level switches represent a modern and reliable solution for monitoring liquids in industrial tanks. Furthermore, they allow accurate measurements even when fluid characteristics, such as density, dielectric constant, or pH, change. This eliminates the need for frequent recalibrations and increases process safety.

Choosing the right technology for multipurpose tanks

When the process requires safety interlocks to prevent overflows, it's essential to choose reliable equipment. In this context, ultrasonic switches Magnetrol stand out because they can be applied to different tanks within the same industrial unit. Consequently, they help reduce costs and minimize process downtime. Furthermore, their quick installation ensures agile and efficient commissioning.

How they work

The switches use ultrasonic waves emitted by a transmitter crystal. The signal propagates only when the space between the switch and the liquid is filled. Therefore, constant adjustments are not necessary. This technology allows for accurate measurements without direct contact with the fluid. Furthermore, it increases the equipment's durability and ensures reliability, even under adverse conditions of temperature, pressure, or variations in the liquid's properties.

Benefits

  • Easy installation, no calibration required;
  • No moving parts, which reduces maintenance;
  • Resistant to variations in density, dielectric constant, pH and other fluid parameters;
  • Available in different materials to suit different applications;
  • Two actuation points and remote mounting options;
  • Low cost and advanced features such as self-test and time delay.

operational benefits

For maintenance professionals, Magnetrol ultrasonic switches significantly reduce downtime and eliminate recalibration issues. Furthermore, a single switch can handle different fluid types by simply adjusting the insertion length. This means installation can be done horizontally or vertically. This flexibility also simplifies inventory management and helps reduce operating costs.
