Fair prices and high-qulity products have made Greisinger GmbH a company to be reckoned with on the measuring devices sector, the company’s developing process has been steadily going upwards for the last 30 years. Globally operating and well-known companies are now amongst their regular customers. All Greisinger products are developed and produced in Germany as the only way to ensure the high-quality standards of the products. The quality management system is certified according to ISO 9001:2008 and additionally for potentially explosive atmospheres according to EN 13980: 2002. Development, production and marketing are certified according to Directive 94/9/CE since May 2003. Several products are already examined and certified according to the Directive 94/9/CE. Features • Water-proof (device and plug-in connections); • Serial interface; • Data logger and alarm function; • Peak value detection (1000 measurements/s); • Leakage test; • Robust silicone protection cover; • Large double display; • Background ilumination. Application • industry and craft. • HVAC: heating, ventilation, air conditioning. • leakage test / pressure test. • chimney draft measurement: under pressure. • leakage test at buildings (i.e. 4 Pascal test). • measurements of gas and oil firings. • automobile tra
Electronical Ignition Sytems high frequency and high voltage > 20 000V • Circuit board assembly • Compact design • For unipolar or bipolar ignition • For one or two ignition points • Stringent individual quality-testing • Self-extinguishing potting and housing material Ignition transformers from HAHN guarantee safe and stable ignition of your gas-powered heating systems. Compact in design, they are ideal for use with printed circuit boards. Within our comprehensive Quality Management System which includes several interim checks, each component is subjected to a final 100 % test. In this test, not only the characteristic data are checked but a high-voltage insulation test is carried out. The specially selected components are all subjected to a glow wire test according to DIN EN 60 335-1:2005. Eco Design – HAHN Solutions Transformers fulfilling the new guidelines of “Energy using products” (EuP). The EuP Serie 2013 of HAHN is perfect for applications of the electric power supply in electrical and electronic household and office equipment with “stand-by” and “off” conditions. Already today where a reduced power consumption of P0 < 0,4 is requi
Trade reliability, soundness of every action, speed and flexibility are the motto of Morek company. Morek operates in the territory of Lithuania, Latvia and Estonia. It manufactures automatic and electrical engineering subassemblies. The products offered by Morek Group are also available in Poland – in TME range of products. The assortment includes, among others: terminals and splice terminals. Electrical engineering, power engineering, industrial automatics are the areas where the necessity of connecting high-current power leads is often required. The system of mounting equipment on a DIN bus, commonly used in automatics, greatly facilitates installers’ work, it has been tested against durability and comfort of work. At the same time, it ensures very good after-market service of the used equipment. Damaged equipment can be quickly replaced with a working one, and such replacement does not cause a long down time, e.g. of a manufacturing line. As electricians say: “each equipment works more efficiently when it is connected to the mains”. However, the problem is how to provide proper quality of such connection. The difficulty of this task increases proportionally with the increase of distributed currents intensity. One of the most reliable methods of fast installation of connection el

When I first began working with fluid dynamics, I was advised the field was as much an art as a science. Working to improve the efficiency of industrial pollution control equipment through better flow distribution, we studied field test data, developed solutions, built scaled models to test them, and then often held our breath when it came time to see if they scaled up properly. Fluid dynamic calculations often take on assumptions of idealized conditions, when the actual case may be far from it. Even after running highly complex computer modelling, engineers frequently find themselves making final design adjustments to designs in their laboratory. by Donna Sandfox, Product Manager, Omron Electronic Components LLC The behaviour of gas flow and achieving a stable, accurate mass flow measurement is affected by many factors. The composition of the gas will affect properties such as density and thermal conductivity. Environmental conditions like temperature, humidity and altitude play a part, as does the medium through which the flow is moving. The surface roughness of the tube/Mass flow sensors are often preferred to volumetric sensors, as volume is dependent on pressure and temperature, while the mass can be thought of as “how much” (not to imply that mass flow sensors are completely immune to these changes, particularly temperature). Going back to basic thermodynamics is the Ideal Gas Law (PV=nRT) - a prime example of a formula assuming ideali
