Tiedemann Ring Loadcells, manufactured for more than 60 years and available in Australia from SI Instruments, offer high precision instruments for mechanical force measurements of tensile and compressive forces. The capacity of the Ring Loadcells range from 50 N to 200 kN.

These Ring Loadcells are used where measurements may allow only minimal length changes as well as in locations where there is little room for the measuring instrument. Applications include R&D, quality and manufacturing control, high-precision measurements in mechanical engineering and vehicle manufacturing e.g. in test stands for brakes, in machinery and transport equipment. Other applications include the measurement of cable tension on overhead wires, as an extension would lead to an increase of slack span. 

The Ring Loadcell consists of a special shaped elastic steel ring attached with two facing drawbar eyes and pressure seats. A load on the ring leads to a slight deformation, which is measured with a precise dial gauge. These Loadcells use no power or batteries, are intrinsically safe and can be used in hazardous areas.

 The indicator on Tiedemann Ring Loadcells can be set in such a way that it displays the maximum force in one measuring run. This is of advantage for fast processes and during experiments where reading of scale is difficult or not possible.
