The unique design principle, in combination with the FlexLock installation kits, makes it possible to counterbalance movements arising from mechanical or thermal expansion or contraction of the vessel or its supporting construction. A particular design characteristic is that the overall height and shape of the load cell remain unchanged, even after two decades of use. Alongside this, the unit has an especially high overload capacity of up to 200%. 特性 100t, 200t, 300t Typ L/LA/N/NE 1. Easy to install 2. Full stainless steel housing 3. Wide temperature range 4.
