The world's most accurate ultrasonic controller for level measurement

Siemens Industry Automation Division announces Sitrans LUT400 series ultrasonic controllers with one-millimeter (0.04-inch) measuring accuracy.

These new controllers offer the highest accuracy available on the market and ensure consistently precise measurements. The compact, single point ultrasonic controllers continuously monitor and control level in liquids, solids, or slurry applications for a wide range of industries.

The controllers are available in three models: the Sitrans LUT420 Level Controller, Sitrans LUT430 Level, Pump, and Flow Controller, and Sitrans LUT440 High Accuracy Open Channel Monitor (which also provides a full suite of advanced level, volume, and pump controls). The series is suitable for an array of applications, including those in water/wastewater treatment facilities, manufacturing processes, and industrial storage.

With these new controllers, operators can be confident of level or flow measurements thanks to Sitrans LUT400's patented filters and algorithms. The high accuracy of these new controllers results in cost-effective operations: inventory monitoring is always precise, processes are better controlled, and expensive spill cleanups can be avoided. With energy cost reduction strategies growing in importance, the Sitrans LUT400 controllers assist water/wastewater facilities in reducing their overall energy expenses with a real-time clock and energy saving algorithms for reducing pump operations during peak energy periods.

The Sitrans LUT400 series controllers feature an intuitive user interface. The controllers can be programmed in less than one minute using the graphical Quick Start Wizards. The backlit display is easy to read in all lighting conditions. Sonic Intelligence, Siemens echo processing technology for ultrasonic level instruments, continuously evaluates and adjusts for noise level and changing process conditions. All three models are compatible with the full line of Echomax ultrasonic transducers from Siemens. The Sitrans LUT400's datalogging capabilities allow users to store and review datalogs or transfer them to a computer. In addition to local programming, the controllers also support remote configuration and diagnostics with Siemens Simatic PDM (Process Device Manager), Emerson AMS, FC375/475, or FDTs (such as PACTware) using Siemens DTM.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

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...
