In industrial production lines dedicated to making French fries, veggie burgers, and other potato-based products, frying is a stage that is as essential as it is delicate. The systems operate continuously, and the oil can reach temperatures ranging from 140 to 190°C. In such an extreme environment, even a small error can turn into a serious problem, and overflowing fryers, pumps running dry, and oil degradation can cause machine downtime that directly impacts productivity.
The application case presented here highlights how appropriate measurement instrumentation can reduce the risk of unexpected failures and extend the service life of frying machines.
For industrial applications, it is essential to have reliable level switches capable of responding precisely when hazardous conditions arise. This is where Vegaswing and Vegapoint come into play—two technologies designed by Vega to ensure safety even under the most demanding conditions.
High-Temperature Sensors
Vegaswing is a device that detects when the level threshold is reached, regardless of the substance’s density and viscosity or the presence of foam and turbulence. The 63 version, used in many food applications, can also be installed with an extension up to six meters long, with millimeter-level precision at the trip point. This feature makes it particularly suitable for deep-fryers, where hot oil is constantly in motion and operating conditions change rapidly. The sensor can serve as protection against overfilling, prevent dry running, and ensure reliability even in the presence of vapors and process residues.
Based on an advanced capacitive principle, Vegapoint provides comprehensive protection in areas where immediate and visible detection is required. The 360° light signal facilitates monitoring by operators, while the stability of the electronics ensures reliable and l operation even during intensive cleaning cycles or rapid changes in the level of the measured substance. It is particularly useful in all applications where the presence or absence of oil must be detected promptly to prevent damage to machinery and components. The integration of these sensors has enabled a major industry player to stabilize its frying process. The combination of continuous level measurement and threshold switches has, in fact, helped reduce machine downtime, improved the quality of the finished product, and made inventory management in storage tanks more efficient. These are robust, low-maintenance instruments, and their use has also helped extend the operational life of machinery and components. In an industry where every interruption can result in significant losses, the Vegaswing and Vegapoint sensors are a key element in making industrial frying safer, more stable, and more efficient.
