Vibratory switches for liquid media

25.06.2008
The new Sitrans LVL100 and LVL200 vibratory switches from the Siemens Industry Automation Division are suitable for signaling when the level of liquid media is sufficiently high, liquid media is required or needs to be refilled, and for protecting pumps.

The compact and user-friendly switches measure reliably even if the conditions change, for example variations in the dielectric permittivity of a medium or the formation of vapor or bubbles. Sitrans LVL100 and Sitrans LVL200 are used in storage and process applications and can be connected to any signaling systems.


The vibratory switches are insensitive to external vibrations, and have a particularly long service life. Both switches are equipped with a special, extremely reliable piezo actuator, and are also suitable for high temperatures. If the electronics detects damage or corrosion, the fail-safe switches trigger an alarm.

Sitrans LVL100 is suitable for applications where space is limited, for pressure vessels, and for protection against running dry. Due to its compact design, the switch can be mounted vertically, horizontally or inclined. It is suitable for all pipelines with a nominal diameter of DN25 and above.

In compliance with SIL2, Sitrans LVL200 has a safety shutdown for detection of minimum/maximum levels. The new vibratory switch operates extremely reliably even at high process temperatures up to 250 degrees Celsius.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
