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: 'Nanochains' could increase battery capacity, cut charging time

How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current to run a device and ultimately fails.

Materials with a higher lithium ion storage capacity are either too heavy or the wrong shape to replace graphite, the electrode material currently used in...

Im Focus: Happy hour for time-resolved crystallography

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.

The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.

Im Focus: Modular OLED light strips

At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.

Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often...
