SDD
Boundary Surface Slide Displacement Measuring Systems
The SDD is for measuring relative displacement on boundary surface between banking and bedrock. It consists of a fixing pile, fixing panel and strain-gage displacement transducer BJB-D-S with moving element. Rated Capacity: 500 (±250) to 2000 (±1000) mm Nonlinearity: Within ±2% RO Rated Output: 1 mV/V or more
