A Sunny Mini Central mounted with a ground-mounted system in Speyer, down the Rhine A Sunny Mini Central mounted next to photovoltaic solar modules. The company was founded by Werner Kleinkauf and former board members Günther Cramer (1952–2015), Peter Drews and Reiner Wettlaufer as a separate company from the University of Kassel, subsequently renamed in 2004 to SMA Technologie AG.
SMA connectors are rated for up to 500 mating cycles, [8] but to achieve this it is necessary to properly torque the connector when making the connection. A 5 ⁄ 16 inch torque wrench is required for this, set to 3–5 in·lbf (0.3 to 0.6 N·m) for brass, and 7–10 in·lbf (0.8 to 1.1 N·m) for stainless steel connectors. Flats are sometimes ...
The impingement surface can be formed in a spiral to yield a spiral shaped sheet approximating a full cone spray pattern or a hollow-cone spray pattern. [4] The spiral design generally produces a smaller drop size than pressure swirl type nozzle design, for a given pressure and flow rate. This design is clog resistant due to the large free passage.
Agricultural sprays include the spraying of cropland, forest, turf grass, and orchards. The sprayer may be a hand nozzle, on a ground vehicle, or on an aircraft. Herbicides, insecticides and pesticides are spray applied to soil or plant foliage to distribute and disperse these materials. See aerial application, pesticide application, sprayer ...
Aerial video of a sprayer (unfolding and driving) A sprayer is a device used to spray a liquid, where sprayers are commonly used for projection of water, weed killers, crop performance materials, pest maintenance chemicals, as well as manufacturing and production line ingredients.
The two most prevalent shape-memory alloys are copper-aluminium-nickel and nickel-titanium (), but SMAs can also be created by alloying zinc, copper, gold and iron.Although iron-based and copper-based SMAs, such as Fe-Mn-Si, Cu-Zn-Al and Cu-Al-Ni, are commercially available and cheaper than NiTi, NiTi-based SMAs are preferable for most applications due to their stability and practicability [1 ...
SMA* (Simplified Memory-bounded Algorithm), a shortest path algorithm; SMA connector (SubMiniature version A), a coaxial RF connector; SMA 905 or F-SMA I, SMA 906 or F-SMA II, an optical fiber connector; SMA or DO-214AC, a variant of the DO-214 diode package; Surface-mount assembly, in electronics
Stone mastic asphalt (SMA), also called stone-matrix asphalt, was developed in Germany in the 1960s with the first SMA pavements being placed in 1968 near Kiel. [1] It provides a deformation-resistant, durable surfacing material, suitable for heavily trafficked roads.
