Key Benefits at a Glance

The world of fluid sensor technology is extremely diverse and complex. With a variety of sensor types, features and designs, choosing the right component for a specific application can be difficult. Our modular weFlux² and LevelTech family provide clear guidance here. It simplifies the selection of the right sensors for a wide range of requirements in areas such as food, beverage and pharmaceutical production, and ensures efficient and reliable process monitoring.

Process Monitoring for Maximum Transparency

Continuous monitoring and analysis of production processes are required in order to assure consistent top product quality. Fluid sensors acquire all relevant process values in real-time and detect even the smallest deviations, so that you can respond quickly to changing conditions. Thanks to the transparency of the processes, valuable information can be used to optimize processes and conserve resources. This results in increased efficiency and productivity, and secures a competitive advantage.

The graphic shows examples of process monitoring tasks which are executed by sensors – for reliable and stable processes.

Smart Communication with IO-Link

Simple Networking, Efficient Control

Fluid sensors use the IO-Link communication standard to ensure seamless integration into digital processes. The sensors communicate reliably with all common control systems via the manufacturer-independent interface and can thus be easily integrated into existing networks. IO-Link enables fast and precise data transfer, enabling efficient process monitoring and remote configuration of the sensors. This increases production flexibility and efficiency and supports the implementation of Industry 4.0 solutions.

Applications

Vacuum Level Control in Fragrance Production

In the perfume industry, sensors in stainless steel housings precisely record the minimum and maximum levels of aromatic substances in pressure vessels. Two measuring points, below and above the tank, measure regardless of viscosity, density or color. An LED indicates the fill levels.

Temperature Measurement with Processed Cheese Filling

In processed cheese production, a temperature sensor in the filling line ensures that the temperature remains above 80 °C. If it falls below this, filling stops and the cheese is returned to the melting tank via a valve and reheated.

Vacuum Monitoring in Glass Bottle Production

In glass bottle production, pressure sensors precisely monitor the overpressure in the body and the vacuum to the finished mold. Deviations from tolerances lead to automatic rejection of faulty bottles to ensure quality and efficiency.

Temperature Measurement of Swimming Pool Water

Temperature sensors monitor the water temperature in swimming pools to ensure a pleasant experience and hygienic disinfection. They measure the efficiency of heat sources and ensure precise temperature control.

Temperature Measurement in Milk Collection Tanks

Temperature sensors in dairies measure the milk temperature precisely and work even in sterile cleaning up to 150 °C. Thanks to the welded adapter and immersion sleeve, they can be hygienically mounted and removed without opening or emptying the tank.
