Design and Application of S-Type Load Cells for Tension and Compression Force Measurement

S-type load cells, also known as tension load cells, are used in tension-weighing applications to convert suspended tanks or other hanging devices into weighing systems. The cells use a reliable strain gauge design with excellent measurement stability. Pair the load cells with optional tension weigh modules to integrate a complete solution into your system.

METTLER TOLEDO offers a wide range of S-type load cells with capacities from 50 kg to 10 t (50 lb to 22 klb) and in nickel-plated alloy steel or stainless steel construction. They are available in legal-for-trade accuracy levels according to OIML R60 (OIML C3) and NTEP HB44 (NTEP 5000d). Tension load cells are available for hazardous area applications and are approved according to ATEX, FM (Factory Mutual), and cFM (Canada). They meet ingress protection class IP67.

To ensure the utmost in safety and performance, our S-type load cells can be paired with METTLER TOLEDO mounting hardware, becoming a model tension weigh module assembly. These assemblies provide engineered components that deliver proven safety and performance.

Traditional calibration methods are time-consuming, expensive, and typically deliver uncertain accuracy and traceability results. The innovative RapidCal™ method from METTLER TOLEDO offers economical tank scale calibration that is traceable and achieved without using test weights or purified liquids. Additionally, by eliminating costly material substitution, contamination risk is eliminated.
