Application flexibility with guided wave radar

- New product family of Sitrans LG radar level transmitter measures using guided waves

- Four basic versions and wide-ranging configuration options cover a particularly broad application spectrum in all process industries

-Also suitable for use in hygienic applications and in harsh environments

With its new Sitrans LG series, Siemens is offering a flexible portfolio of guided wave radar transmitters suitable for virtually any type of industrial application.

Sitrans LG radar level transmitter measures

The modular design of the four basic versions Sitrans LG240, Sitrans LG250, Sitrans LG260 and Sitrans LG270, with numerous configuration options, allows for level measurement in the oil and gas, chemical, pharmaceutical as well as food and beverage industries.

The modular radar transmitter covers a broad application spectrum for the measurement of liquids and interfaces, from aggressive materials to hygienic conditions and complies with SIL2 safety standard.

Sitrans LG240 was specifically designed for hygienic applications in the pharmaceutical or food and beverage industries and has the required EHEDG, FDA and 3A certificates. The Sitrans LG250 is ideal for the wide range of liquid level measurement such as those in water treatment applications. The Sitrans LG260 version accurately measures levels of solids, granulates and powders even with extreme dust. In particularly harsh environments with high temperatures up to 450 degrees Celsius (842 °F) or high pressures up to 400 bar (5800 psig), such as those in the chemical or petrochemical industry, the Sitrans LG270 is the best choice.

Sitrans LG's high frequency microwave pulses are transmitted down a rod or cable, offering reliable measurement with up to two millimeter (0.08 inch) accuracy in applications with corrosive vapors, steam, foam, surface agitation and/or liquids with high viscosity, low level, and varying dielectric or density.

Installation is simple with the device's range of pre-configured options, such as customized enclosure materials, process connections, approvals and communication options. Users will be operational in minutes with four-button programming directly at the instrument or through remote configuration with Siemens Simatic PDM (Process Device Manager) via HART communications protocol.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
