The next generation for automated depth profile monitoring. Compared to previous developments, the cable is spooled onto the drum with this winch. A cross-thread spindle acts as a linear guide to ensure the cable is placed on the drum in an orderly manner. The overall system is much more compact and versatile.
Technologies used:
- Own construction of the winch technology
- Rotating signal transmission
- Cross-thread spindle
Automatic depth profile recording
A multiparameter probe is moved in the water column of the water body. Depth profiles are started several times a day. The measuring probe positions itself automatically at defined measuring points. Subsequently measured values of all sensors are read and stored tagged with the corresponding depth. Then the multi-parameter probe is positioned at the following depth and the measurement recording is continued.
Measuring technology
The winch is compatible with all multi-parameter probes available on the market. If you already have a measuring system, it can usually be adapted to the system. HydroLab probes from OTT HydroMet and In-Situ Aqua TROLL probes have been used successfully for many years. Data acquisition and control technology are reliably coordinated.

Locations of operation
The winch and measurement technology can be carried out on fixed structures such as dams or extraction towers as well as on self-sufficient measuring buoys. Accessibility of the multi-parameter probe and the winch technology is of high importance for maintenance work and adjustments. The winch and multi-parameter probe can be moved to a platform for maintenance using a foldable boom when permanently installed. In doing so, a sufficient distance to the structure is maintained during operation. In the maintenance position, the multiprobe can be lowered. When operating on buoys, the multiprobe is lifted from the buoy above the water surface for maintenance purposes. Power is then supplied by solar cells and rechargeable batteries.
