Settlement measures in earthworks, embankments , foundations etc.
The profilometer ST150 has been designed to measure vertical settlements in embankments or in foundations. The particular care with which the instrument was created guarantees high precision and reliability of the measurements.
The system is composed of: sensor (pressure sensor), reference cup , cable , hydraulic tube and from PROFILAB readout unit.
The sensor is inserted on one side of the polyethylene pipe (previously laid horizontally), it is pulled from the opposite side by means of a cable. steel or pushed by a glass fiber probe. In the case of blind tubes it is possible to use a blind head with pulley, in order to insert and slide the sensor on the same side of the tube.
The sensor is slid inside the tube and stopped at every meter. The pressure sensor positioned inside it detects the level of the liquid acting on the sensitive membrane and consequently, the difference in height between the reference cup and the probe. The PROFILAB readout unit will acquire the data and store them.
