The WAS range of load cells from LCM Systems have been specifically designed for applications where there is a requirement for the force application component to pass through the centre of the load cell. This style of product is often referred to by different names, including annular load cells, force washers, donut load cells, through hole load cells etc.
The main application for the WAS series is measuring the tension in bolts for safety monitoring and control, or general quality control. LCM Systems specialise in the design of custom load cells, so have also been heavily involved in designing similar products for rock anchor force measurement, fork lift truck weighing, and tie rod tension monitoring.
If you have a requirement for an annular or through-hole load cell that can not be satisfied with the standard WAS series, then contact our technical department with your requirement, and we will probably be able to solve your application problem for you.
The WAS series can be supplied as a stand alone product or be incorporated into an instrumentation package, to meet your specific application requirements.
