• Simple assembly
  • No maintenance effort
  • Also ideally suited for fertiliser flow monitoring
  • The blockage sensor 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 fertiliser in precision planters as well as to monitor seeding in pneumatic seed drills. Thanks to its modular design, the blockage sensor can be adapted to any hose diameter, enabling other application options.

    The innovation of the blockage sensor consists in the application of the patented piezo technology. The seed or fertilizer hoses are neither tapered nor are any edges introduced. A simple continuous tube with the same diameter as the hose to the machine is sufficient basis for the sensor to perform its measurements. Even with high degrees of soiling, which can occur due to dust from dressing or artificial fertiliser, the sensor does not lose its detection accuracy and performance, since the utilised stainless steel tube is virtually continuously cleaned automatically by the impacts of seed or fertiliser. This results in less downtime for the operator due to laborious opening and cleaning of the sensors.

    The blockage sensor detects all common spreading materials – ranging from large seeds like maize, soya and fertilisers via all sorts of cereals through to fine seeds and micropellets. Spreading errors are automatically detected and displayed. An integrated LED indicates the blockage and assists the user in troubleshooting.

    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, easy to retrofit and consisting only of implement monitoring, is also possible.
