Blockage Sensors Ensure you are always delivering the seed to the ground with the new Blockage Sensor from RDS As drilling becomes more demanding the cost of a partial or complete blockage can be a costly and unsightly mistake. With the optical blockage sensors we can ensure product (seed or fert) is flowing down the pipes when it should be.

The blockage sensors are available in 30mm and 32mm sizes and can easily be fitted in air pipes on the drill. Advantages: • Not affected by different materials Using 4 optical detection elements sampling at 15kHz it means product as small as 1.5mm can reliably be detected at a velocity of upto 22.5 metres/second. • Stainless steel tube • Sensors can be installed in seed or fert pipes • Automatic calibration • Sensor automatically adjusts optical intensity to compensate for foreign material build up on optical elements Sensors are ‘daisy chained’ and connected to a master ECU which then connects...
