    Sensors for collision avoidance in the storage hopper and drop height monitoring

Ultrasonic sensors for agricultural machinery

From the field to the shelf: microsonic ultrasonic sensors convince when used in both field and orchard-based harvesting applications and automated livestock farming.

Our ultrasonic sensors help farmers to sow and plant exactly. Fertilize fields and orchards with the highest accuracy and then harvest the crop precisely and safely.

Feed animals automatically with precise fodder dosing. Clean stall walkways automatically and improve levels of hygiene.

Let's talk about your task. With ultrasonic sensors, we create groundbreaking solutions. In all possible applications. Sometimes even in impossible ones.

The right solution for every application

Working plattform: track guidance

Our mic ultrasonic sensors or pico+ ultrasonic sensors measure the lateral distance to vines or trellises. The control system automatically adjusts the guidance of the working platform, thereby allowing harvesting machines to drive through rows of vines or trellises evenly.

Field sprayer boom: Height adjustment

Several wms ultrasonic sensors or mic ultrasonic sensors continuously measure the distance to the crop to ensure height regulation of the field sprayer. The field sprayer control system uses the measured distance values to compensate for unevenness in the soil or different plant heights. This allows for the even distribution of pesticides or fertilizers.

The all-metal housing of the two sensor families is specially designed for outdoor applications on agricultural machines.

Conveyor belt in the storage hopper: Drop height monitoring

Crops placed in a bunker via a conveyor belt must not be deposited from too high a drop height. The lcs+ ultrasonic sensor or cube ultrasonic sensor permanently measures the distance to the pouring cone to maintain it at a constant value. The control system detects the distance value and readjusts the height of the conveyor belt. This ensures that sensitive crops are always stored from a low drop height and thus do not suffer damage.

Feeding robot: maintaining clearance from the gate

Feed sliders are used for the automatic feeding of cows in stalls, dosing the required amount of feed and pushing it if necessary.

mic ultrasonic sensors or lcs+ ultrasonic sensors measure the distance to the gate and the animals from the feed pusher; these values are used to order the feeding robot to push the requisite amount of fresh feed.

Potato planter: Counting the seed potatoes

The potato planter places the seed potatoes in the soil and then forms ridges. The machine counts the seed potatoes using pico+ ultrasonic sensors to ensure an even distribution of the seed.

Warehouse filler: collision avoidance

The use of a warehouse filler to fill crops in a bunker ensures their even distribution. Several lcs+ ultrasonic sensors permanently measure the distance to the walls to avoid a collision with the walls in the bunker. cube ultrasonic sensors can be used as an alternative.

The control system detects the distance values and regulates the alignment of the warehouse filler. This ensures that the crops are stored safely and that the warehouse filler does not collide with the walls.

Cleaning rotos in the cow shed: Automated guidance

Cleaning or manure removal robots are deployed for the automatic cleaning of walkways and slatted floors in cow barns.

crm+ ultrasonic sensors on the cleaning robot measure the distance to the gate and the animals. Using the measured distance values, the cleaning robot works reliably to ensure hygiene.

Beet harvester: Scanning the floor contour

When harvesting field crops, the ground contour is scanned. With a beet harvester, the foliage of the beet is first removed before it is pulled out of the ground. The ground contour is recorded in order to achieve optimal adjustment of the cutting unit of the beet harvester. To this end, several mic ultrasonic sensors or wms ultrasonic sensors permanently record the distance to the ground. The control system detects the distance values and readjusts the height of the cutting blades. This ensures that only the smallest possible part of the beet is cut off.

Beet harvester: Filling level measurement in the loading bunker

During harvesting, multiple mic ultrasonic sensors or lcs+ ultrasonic sensors can be used in harvesting machines such as beet harvesters to measure the filling level in the loading bunker for the crops. This enables efficient harvest logistics and avoids interruptions caused by the overfilling of the harvesting machine.

Round baler: Film monitoring

Ultrasonic sensors with a switching output can be used to perform film tear monitoring. We recommend the use of pico+ ultrasonic sensors in cramped installation conditions. If the diameter of the film roll is also to be monitored, an ultrasonic sensor with analogue output can be used.

Seeder: Seed filling level control

Ultrasonic sensors provide a reliable method of monitoring the filling level in seeders. The sensors detect filling levels from a few millimetres up to 3 metres without contact. Choose between mic ultrasonic sensor or pico+ ultrasonic sensor with one or two switching outputs for min/max control or with analogue output 0 - 10 V and 4 - 20 mA for continuous filling level monitoring. This allows even and precise dosing of the seed.

Sprayer: Tree and trellis detection

Deployed to detect the spraying areas, several cube ultrasonic sensors or mic ultrasonic sensors continuously detect the tree rows or trellises. This means that spraying areas can be added or removed automatically via the control system. This minimizes the use of pesticides and ensures their even distribution.

Grape harvester: Automated track guidance

Deployed to guide the path of the grape harvester, two mic ultrasonic sensors or pico+ ultrasonic sensor s continuously measure the distance from the vine rows or trellises. The harvester's control system uses the measured distance values to perform automatic adjustment of the guidance system. In this way, harvesting machines can be driven evenly through vines or trellises.
