Precision Settlement Monitoring System (VW)

Precision Settlement Monitoring System (VW)

Order Catalog


The Model 4675OC Precision Settlement Monitoring System was designed to measure differential settlements with a very high degree of accuracy and resolution, making it suitable for applications of a highly critical nature where the expected settlements are small. The system uses a 3 inch diameter horizontal open channel pipe, which is half filled with water or antifreeze solution and fixed to the structure or tunnel under observation. Sensors are situated at intervals along the pipe and connected hydraulically to the water in the pipe through short lengths of tubing.


Standard Ranges¹ 75 mm
Resolution 0.025 mm
Accuracy² ±0.1% F.S.
Temperature Range −30°C to +80°C (using antifreeze solutions below 0°C)
Dimensions depends on range

¹Other ranges available on request.

²Accuracy can be achieved using polynomial calibration constants.
