Reg No 4-8721 Rev1 Date: 2006-12-27.
Basic function The basic function of the rubber element is to prevent side forces from affecting load cell performance and at the same time, keeping the load carrier in position. The rubber element is not to be seen as a vibration damper although is has a limited damping effect. It is relatively stiff in vertical direction while weak in horizontal direction.
Retaining Function For type 52-02 a spring clip prevents the rubber foot from falling out in case the load carrier is lifted. For Type 52-10 a screw through the cell and loading pin gives the same function. See Figure 3. Figure 3 Installation examples The Load Cells should be positioned so that the load is distributed as equally as possible between them. See examples below.
Installation examples Figure 5 shows the rubber foot Type 52-02 installed under a floor scale. A hook is mounted on the loading pin, holding the ramp in position. Figure 5 Figure 6 Figure 6 shows the Rubber Foot Type 5202 installed, under a tank together with Base Plate 52-00. Fixation plates keep the Rubber Feet in position on the floor, in case of vibrating load carriers or when there is risk for load carrier being pushed out of position.
Fixation plates Figure 8 Normally 2 fixation plates are sufficient, positioned at the 2 load cells which are furthest apart in the scale. The fixation plates shall be well centred to the rubber feet.
Type 52-15, Height Adjustable Rubber Foot The Height Adjustable Rubber Foot is also available as Type 52-15. This version is designed for the BK2 Load Cells. It is available in both metric (M12) and unified (1/2”-20UNF) versions. See Figure 9.
