SI Instruments Tiedemann Ring Loadcells

Tiedemann Ring Loadcells, from SI Instruments, offer high precision instruments for mechanical force measurements of tensile and compressive forces. The capacity of the load cells ranges from 50 N to 200 kN.

The load cells 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 and high-precision measurements in mechanical engineering and vehicle manufacturing, eg, 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 product consists of a specially 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. The product uses no power or batteries, is intrinsically safe and can be used in hazardous areas.

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