Cement level measurement applications in storage warehouses

In level measurement it is detected and yes displays the level of a product in a tank or in a silo with the aid of a LASER distance meter, then converting the measurement into an analog electrical signal or into a data packet to be sent to a remote supervisor. The level signal can be viewed directly on site via a local display or integrate into a process management and/or control system.

In the storage depots, the cement is distributed by train or large trucks to several large storage boxes. Several laser distance meters of the type are employed to provide the crane operator with accurate information about the amount of cement that each of the crates can still contain. Communication via Profinet or Ethernet / IP facilitates the collection of distance information from various measuring devices in a central location. Efforts for the wiring of the measuring points are substantially reduced whether a wireless connection or an existing Ethernet network is used. The functional reliability of the entire system is constantly monitored thanks to the control system distributed over the Profinet or Ethernet network.

Level measurement of grains and powders in food silos

Silos are structures used to store agri-food industry products. They are primarily used for storing grains (corn, wheat, rice, legumes, and similar products). Knowing the level of material contained in each silo is crucial for the logistical management of materials and for evenly distributing available resources.

Laser distance meters allow for contactless measurement of the level of grain, whether whole or ground, inside silos. Based on the silo's geometric shape, it is possible to determine the volume of stored material and also approximate its weight.

Reliable measurement of position and distance

When operating cranes, it's essential to have information about the current position of moving parts. In these cases, laser distance sensors are used with the support of reflectors.

With a measurement uncertainty of ± 2 mm and a speed of up to 50 measurements per second, the devices are ideally suited for reliable position measurement.
