NEWS AND UPDATES
The new designed low air velocity transmitter EE660 has three selectable working ranges and two selectable analogue outputs. The EE660 is designed for highly accurate measurement of very low air velocity. It is the ideal solution for laminar flow control and special ventilation applications. e.g. in clean rooms. The EE660 operates on the hot-film anemometer principle, which stands for excellent accuracy down to 0.15 m/s (30 ft/min) and high insensitivity to pollution. Low angular dependence and the mounting flange enable easy, cost-effective installation. The EE660 is available in a wall and duct mount version and as a version with a remote probe. A display is optional.
EE671 is a compact air velocity probe for HVAC applications. The built-in flow sensing element VTQ combines the advantages of state-of-the-art E+E thin-film manufacturing and of the newest transfer molding technology. It operates on the hot-film anemometer principle and ensures high accuracy and reproducibility as well as long-term stability and outstanding resistance to pollutants. EE671 is available with fix installed cable or with plug connection. The measured air velocity up to 20 m/s (4000 ft/min) is available as linear voltage output 0 – 1 V, 0 – 5 V or 0 – 10 V. The alignment strip on the probe and the matching mounting flange within the scope of supply simplify installation and correct positioning in the air flow. The flange enables the immersion depth to be infinitely variable.
Our factory LitreMeter is specialized in flowmeters for extraordinary applications. The Rotary Piston Positive Displacement Flowmeters series VFF are tuned for injection of low doses of chemicals in all kind of processes. Mainly it is the process designed to assist in the production of oil. Various chemicals are injected into the crude oil to provide a degree of protection. For example a scale inhibitor will prevent the build-up of scale on the pipes and fittings used to transport the oil on its journey to the refinery.We have included a special section for chemical injection flowmeters on our website.
The EE300Ex humidity/temperature transmitter Re-ensures safe operation in explosion hazard areas and fulfils the requirements of the ATEX Directives on intrinsically safe operating equipment. The device can therefore be used both in gas and dust explosion hazard areas.In the same way as humidity measurement in air, the EE300Ex can also be used for moisture measurement in oil. The moisture content of an oil can be issued as absolute in [ppm] or relative as water activity [aw].
