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: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
