GLÖTZL - Model ET4 -Electric Settlement Cell Sensor

The electric settlement cell comprises a relative pressure sensor that is loaded with a water-glycol mixture or, upon requirement, with silicone oil via a plastic double line. The sensor measures the hydrostatic pressure in comparison with a reference point that is installed outside the settling area. These double lines are designed as a continuous ring for subsequent filling. Any occurring settlement causes a change of position of the sensor which in turn causes a change in pressure of this fluid (difference between central unit and cell) which is then measured. Design and structure of the cell can be optionally changed upon customer requirements. The figure shows a standard unit with a 30x30cm stainless steel plate for installation in a fill or embankment. The available versions of the cells are listed in the table below.
