Tension load cells are very versatile with low profile and welded stainless steel design. They are very accurate in measuring compression and tension forces. These kinds of tension load cells, especially those that have male threaded stud connections for load attachment, are designed to collect tension and compression information under harsh conditions.
They are also able to measure bi-directional units which range from 1kg to 100 tons in 2" diameter with an FSO linearity of +/- 0.15%. The tension load cells have an internal design that allows for superior long term stability and significantly reduces the effects of small-axis loads. Tension load cells are highly accurate and leave a small foot print.
Some advantages of tension load cells include easy installation, high accuracy, reliability, ability to be customized, high side load reduction, better sealing and protection, small, and inexpensive. Some down sides of the tension load spring are that the strain gauges are exposed and require protection, no load movement is allowed and the loads must be centered.
Therefore, there are a few things to consider when purchasing a tension load cell. The first being the duration of measurement (short-term duration with a tare, or long term duration without a tare), output requirements, direction of loading (tension/compression, or both), percent of accuracy requirement (as a percent of reading or full scale output), operating temperature conditions, options for mounting, certification requirements, operation costs and other accessories needed.
