ME-Blockage Sensor

ME Blockage measures the flow in all agricultural implements where individual particles are conveyed with air or by free-fall.

The sensor is primarily used to monitor the flow of fertilizer in precision planters as well as to monitor seeding in pneumatic seeders. Thanks to the modular design ME Blockage can be adapted to any hose diameter, enabling other application options.

The blockage sensor detects all common materials – ranging from large seeds like maize, soya and fertilizers via all sorts of cereals through to fine seeds and micropellets.

The system can be used in different ways. It is either integrated in the existing seeder and thus communicates with the job computer or the system operates independently and is directly integrated on the ISOBUS as an implement. A stand-alone version, consisting only of implement monitoring, is also possible.



The ISOBUS PLANTER-Controller is a control system for implements with mechanical, central or single drive. It supports up to 128 rows with SECTION-Control.

The job computer regulates the seed rate according to the set target rate in seeds per hectare. Both electric and hydraulic motors can be actuated to regulate the rate. Using sensor technology (e.g. optical sensors or PLANTirium sensor), the seed is counted and monitored on each row.

The rate control system for fertilisers and micropellets is also possible.

In addition, different  shut-off clutches can be switched manually or automatically (SECTION-Control) for each metering unit.

The motor control of the application rate per row allows the optimum seed placement and holds a great savings potential. On more complex implements with supplemental fertiliser placement, the system can also regulate this target rate according to specifications.



The ISOBUS DRILL-Controller seeder is a control system for implements with up to four metering drives (MULTI-Control). The job computer regulates, monitors and controls the connected hydraulic functions of a seeder.

The rate is regulated according to the set target rates for each metering unit with up to four different products (seed and fertiliser). Both electric and hydraulic motors can be used to achieve regulation.

For implements with more than two metering drives, the system is extended with an additional job computer. This solution is therefore ideal for all manufacturers, from the simple one-hopper implements all the way to complex large-scale implements with simultaneous spreading of fertiliser and seed.


PRECIMAT is a monitoring device for precision planters with seed counting.

Up to 12 seeding units can be monitored with optical sensors. It is also possible to shut off up to 12 seeding units. Alternatively, on implements with more than 12 rows, it is also possible not to use any monitoring and therefore shut off up to 18 seeding units.

In addition to precision planting, the PRECIMAT can also be used as a hectare counter for all other applications.



DRILLMAT III is used on seeders to automatically create tramlines. The variety of different pre-programmed rhythms allows for the combination of any seeder working width with the desired tramline spacing.

Seeding can begin both on the right and the left side of the field. Manual switching is also possible. The DRILLMAT III is also used to monitor the seeder. The metering shaft and fan speeds are continuously monitored. A fill level sensor indicates low seed levels. In addition, the DRILLMAT III provides information on seeded areas, area output, covered distance and speed.

PLANTirium sensor

The PLANTirium sensor is the first seed tube sensor that uses imaging sensors. This technology enables the detection of small seeds such as rapeseed or larger seeds such as corn or sunflower seeds, even in difficult conditions. A pattern recognition method is used to distinguish debris from seeds inside the seed tube.

Also, the sensor recognises overlapping seeds as multiples. Active sensor re-adjustment provides reliable compensation for debris accumulating on the sensor (e.g. dust, dressing).

It has an interface for parameterisation and to update the software, and it is capable of sending status messages about its status (e.g. cleaning required) to the master control unit.

Opto-sensor / optical sensor

The sensor consists of a sending and a receiving unit.

The sender produces a light beam in the near-infrared wavelength range. The receiver, which exhibits its maximum sensitivity in this wavelength range, is spatially positioned at a distance opposite to the sender. If this light beam is interrupted by seed grain, it produces an output signal of the sensor.
