SZ-TJH Weight Sensor
Product Overview
The SeeZol ring-type load cell is a high-precision weighing component with a central aperture and ring-shaped structure. It converts pressure or tension into electrical signals for weight measurement. Due to its compact design and strong resistance to off-center loading, it is widely used in scenarios requiring limited installation space and stable measurement performance.
Working Principle
When a weight (or pressure, tension) acts on the ring-shaped sensor, the ring-shaped elastic body undergoes slight deformation, causing the strain gauge to stretch or compress. The change in the strain gauge’s resistance generates a weak voltage signal (typically at the millivolt level) from the Wheatstone bridge. This signal is amplified and then transmitted to the weighing instrument or controller, ultimately converting into a visual weight reading.
Key Features
- Strong resistance to off-center loading (even load slightly offset from center)
- Compact installation (central opening passes bolts, shafts, or cables)
- Wide measurement range (kg to hundreds of tons by elastic-body design)
- High stability, strong vibration / impact damping for continuous industrial use
