LOAD CELL FOR TUNNEL LININGS AND STRUTS
This type of load cell is used to monitor stresses in steel linings, struts, piles and support beams.
It consists of a sensitive pressure pad formed by joining two stiff steel discs at their periphery. The void inside the cell is filled with de-aired fluid. When load is applied to the cell the pressure of the inside liquid changes. The changes in pressure correspond directly to the load applied.
The pressure in the loads cell is measured by a resistance transducer.
Description
Mounting surfaces should be flat and parallel for optimum performance and the use of very stiff bearing plates and load distribution plates is recommended. Electric cable connects the load cells to a suitable remote readout system.
