If the electronic traction machine wants to test the elongation of metal products, let's not talk about the configuration, the range of the electronic traction machine must be given priority! Because there are many kinds of metal products, the ranges will be different according to different metal products, for example, an iron wire and a steel plate, the range gap between the two will be very large! Therefore, before choosing the measuring range of the electronic traction machine, we should first understand what the corresponding metal products are, and then select the measuring range according to the metal products.
Our common metal products in everyday life are iron, copper, aluminum and plastic metals (stainless steel, carbon steel) etc. in the form of filaments, tubes, tapes, plates, blocks etc. Among them is in the case of the same shape of the measuring rangech of aluminum and some synthetic metals is smaller, and in the case of the same metal, the measurement range of the filament shape is smaller than that of other shapes. Compared to the metal type and shape, the main factor affecting the range of the electronic traction machine is the shape.
The measuring range of the filamentary semimetal pulling machine is generally between 1KN and 5KN, depending on the diameter of the filament, the larger the diameter, the larger the measuring range. (*Very large diameter filiform metal is no longer called wire, it is called ribbon or block!)
The measuring range of the tubular metal traction machine is generally about 5KN~10KN, which also depends on the thickness of the Outer wall The greater the thickness, the greater the corresponding measuring range. (*Pipe-packed metals with a very large inner diameter are no longer called tubes, but sheets!)
The measuring range of the pulling machine for strip-shaped metals is in Regel at about 10KN~20KN, which is determined by the thickness and size of the strip The size of the measuring range of the traction machine, the larger the thickness and size, the larger the corresponding measuring range. (Very thick tapes are lumpy!)
The measuring range of the plate-shaped metal-like traction machine is not much different from that of the tape, since its measuring range is also determined by its thickness and size. The range of bulk metal tensile machines is generally above 20kN, because it is very thick and the force is very uniform, so the electronic tensile machine with too short a range cannot be tested. Generally, electronic testing machines are used to test Bulk Metal Products Horizontal Tensile Testing Machine.
