What is an s-type load cell?
S-type load cells are force transducers that are designed for precise tension and compression force measurement, owing their name to their characteristic s-shaped geometry. This shape allows the force to be applied ideally along the longitudinal axis, resulting in high measurement stability and repeat accuracy. S-type load cells are mainly used where reliable force measurement in both directions is required, for example in industrial weighing equipment, material testing or dosing systems.
Where are s-type load cells used?
S-type load cells are used in a variety of industrial applications in which tension or compression forces must be detected in a controlled manner. These include, among others, crane and hanging scales, tensile and pressure test benches, dosing equipment, process monitoring systems and applications in automation technology. Due to their robust design and high measurement accuracy, they are suitable for dynamic measuring requirements and also for permanent force monitoring in different ambient conditions.
For which types of measurement are s-type load cells suitable (tension, compression, both)?
S-type load cells from WIKA are designed for measuring both tension and compression forces. The characteristic s‐shape enables centred force introduction in both directions, ensuring precise, reproducible results both in suspended applications and in pressure-loaded measuring assemblies.
How does an s-type load cell work?
S-type load cells measure tension and compression forces along the axis, with the force being introduced centrally into the s-shaped measuring body via the female threads on both sides. Under load, the body deforms elastically, and applied strain gauges register this deformation as a proportional change in resistance, which is processed by the evaluation electronics into a stable output signal (usually the strain gauges are connected in a Wheatstone bridge circuit).
