About the ALW4 Hermetic load washer
The ALW4-1 Hermetic Load Washer delivers precise force measurements in compact environments. Designed with a stainless steel strain gauge and laser welded construction, it ensures optimal durability, even in harsh industrial conditions. With rated capacities from 1,000 to 20,000 lbf and non-linearity better than ±0.5% of full scale, it is built for performance.
Usage conditions
Thanks to its IP68 rating and compensated temperature range of -15°C to +71°C, the ALW4-1 load washer is ideal for both indoor and outdoor industrial applications. Its 8-pin M12 male connector and robust build make it suitable for embedded use in machinery and structural components.
Possible applications
- Preload control in bolted joints
- Structural health monitoring
- Industrial press force measurement
- OEM integrations in robotics and machinery
- Load monitoring in rotating equipment
