Those dual axis inclinometers are designed to measure very small changes from the vertical level, either on the ground or in structures. They exhibit high resolution and low thermal drift. Their mechanical design and enhanced internal surge protection make them particularly useful for the permanent outdoor monitoring of structures being subjected to various influences such as loading and foundation settlement.TYPICAL USE Off-shore wind turbine foundations Bridges and piers Historical buildings Structural load testing Vessel and pontoon roll and pitch measurement Crane roll and pitch measurement Structural Health Monitoring FEATURES Biaxial High accuracy and resolution Excellent thermal stability 4-20 mA current loops for signal immunity and potentially long cable runs Enhanced surge protection Internal temperature sensor for residual thermal drift compensation Two models for horizontal or vertical mounting Easy to install

In cases where waste liquid’s or suspension’s need to be incinerated, EUROPEM uses liquid fuel injection lances equipped with ultrasonic atomisation nozzles, resulting in very fine droplets and an almost gas-like combustion process. This nozzle uses an atomizing fluid such as superheated LP steam or compressed air. EUROPEM Natural Draft and Forced Draft Burners Different configurations for the atomization nozzle are possible, depending on the burner design, capacity range and the desired spray pattern in relation to the combustion chamber. The nozzle operates based on the Hartmann Generator principle and was originally developed the early 1970s. In 2007, the nozzle was optimized and now has a fuel turndown ratio of 10:1. Hartmann Generator principle: Through a jet nozzle (D), a gaseous fluid flows with supercritical pressure ratio – meaning sonic speed. According to Mach and Salcher a periodical structure will build up in the stream (dotted line). Graph K shows the pressure cycles along the length of the gas stream. Oscillations occur by filling (pressurizing) and deflating the hollow space H. This is the principle used for the Ultrasonic Nozzle. A Hartmann Generator is placed as a concentric ring around a central liquid fuel pipe. The high exit speed of the atomizing fluid (compressed air, steam or combustible gas) alone achieves a rough atomization, caused by the negative pressure. The ultrasonic effect created by the Hartmann Generator oscillates the pre-atomized droplets at a high frequency, and further fragments the droplets into a very fine mist. Advantages: Low and high viscosity fluids are atomized into smallest possible droplets. No limitation on ash content and other solid particles in liquid fuels. Various fuel types can be used in one nozzle, no limitation on fuel mixtures. High durability due to low operating pressure for fuel and atomizer. Different nozzle types to obtain different spraying paterns

Actran VibroAcoustics A complete, robust, reliable, productive and high performing vibro-acoustic CAE module Actran VibroAcoustics is the most complete vibro-acoustic simulation software currently available on the market. Built on top of Actran Acoustics and relying on Free Field Technologies’ powerful finite and infinite element library, Actran VibroAcoustics provides a rich library of elements, materials, boundary conditions, solution schemes and solvers and is used by the most demanding engineers, researchers and teachers to solve challenging vibro-acoustics design problems. To build the structural model in Actran you can rely on its rich material library. Indeed, Actran features not only conventional materials for acoustic or visco-elastic media but also more specific models for porous or incompressible media, composite materials or active components (including piezo-electric ceramics). All material types can be combined in a single model to achieve the most realistic results. A modal basis may also be imported from most structural FEA codes and be used as a representation of the structural model. Your vibro-acoustic model may be submitted to the most realistic working conditions by combining acoustic, dynamic and kinematic boundary conditions, as well as more physical excitations like diffuse sound field and turbulent boundary layer. Actran AeroAcoustics and VibroAcoustics can be combined: modeling complex aero-vibro-acoustics problems has now become reality! The available solution schemes include coupled or uncoupled models in physical and modal coordinates, in frequency or time domain. The very efficient linear equation solvers and the parallel processing capabilities make Actran the solution of choice for solving industrial-size problems in design optimization processes. Target Applications: Automotive: noise related problems from powertrains, intakes, exhausts, passenger compartment, trim, seats, hoses, tires, windows and windshields, audio, HVAC. Aerospace: sound transmission through cockpit and fuselage, noise propagation in air distribution system, response to TBL excitation, random dynamic response of rocket payload at take-off. Consumer goods: telephones, headsets, loudspeakers, hearing aid devices, disk drives, washing machines, refrigerators, cameras. Defense: underwater acoustics, sonars.
