Overview
The FMS CA203.250 load cell is a compact force measuring sensor engineered for dead shaft applications in industrial automation and tension control systems. This sensor delivers 10× overload protection, has no re-calibration required, features a 20:1 force measuring range, and achieves accuracy class 0.5%. The unit includes the CA203 DI125 dead shaft adapter for direct mounting onto existing roller shafts, eliminating the need for shaft modifications during installation.
Key Features
- Stainless steel sensor and aluminum cover for corrosion resistance and durability
- Dual flexion beam design eliminates angular deflection under load and ensures tension measurement with the highest accuracy and reliability
- 250 N nominal force capacity with dead shaft adapter integration
- Built-in mechanical hard-stop provides high overload protection and ensures frequent calibration is not required
- Easy mounting to machine side frame with a single mounting screw or optional mounting brackets
- Foil type strain gauges mounted in a full Wheatstone Bridge configuration for precise tension measurement
Technical Specifications
The FMS CA203.250 is available with nominal force of 250 N, delivers 0.5% accuracy class, features a 20:1 force measuring range, and is constructed with stainless steel measuring body and aluminum housing for maximum durability in wet or corrosive environments.
Typical Applications
- Web tension control on material processing lines (paper, textiles, film, foil)
