Long-Term Results of the Hydrostatic Levelling System at the Swiss Light Source (SLS)

The hydrostatic levelling system (HLS) at the Swiss Light Source (SLS), Switzerland, showed reliable long-term stability over the past years. The high resolution of the HLS allows the observation of ground deformations induced by tidal forces. As a special feature, each level sensor is equipped with a touch point which allows a remote re-calibration of the system. In this presentation, the latest results are discussed and an overview of the HLS design at the SLS is given. In addition, the new PWR (Precision-Wide-Range)-HLS, a more compact OEM - level sensor version, is introduced.
