Drill Monitoring


Seed-flow/blockage monitoring for air drills, seed count and population display for planters, granular fertilizer flow control, hopper level control, shaft rotation guard, fan rpm, hectare counter, tramline regulation – all in one instrument!

The robust, versatile device aimed for use all year round. Integra is capable to process and display the performance of 128 rows at a time on its large illuminated graphic screen. Integra was designed to best fit user’s demand with handy operation and easy survey of seeding process. Two i-LiNE ports enable monitoring of different application rates for seed and fertilizer rows. Easy operation is ensured by direct keys and control LEDs.


System Features

  • Seed-flow/blockage monitoring of 3 products on pneumatic and some mechanic drills
  • Seed count/Fertilizer/Insecticide flow rate/blockage monitoring on planters
  • Full-featured seeding control program for planters up to 24 seed rows + 24 fertilizer/insecticide rows
  • On-the-go calibration of expected seed density
  • Manual or automatic speed tracking
  • Tramline regulation (symmetric or asymmetric rhytms)
  • Row closure motor/actuator end position control
  • Hopper level display with low level alarm
  • 2 rotation guards (one channel with numeric display, e.g. fan r.p.m.)
  • Detection and display of blockages or dust accumulation on seed sensors







Seed Blockage Sensors

DS4000i optomodules are made for seedflow monitoring on drills. Optomodules contain photosensors equipped with 4 infra lights and detect even the smallest seeds like oilrape seed. Seeds do not need to be filled up in the hose reaching seed sensors. Thanks to the easy and precise seed-flow calibration, blockages are detected immediately or soon.

Sensor Features

  • Seed flow/blockage detection (DS4000i)
  • Linear connection of sensors up to 128 rows
  • Calibration of expected seed density
  • Available for air hoses with 25-35 mm diameter
  • Particle detection with 4 infras
  • Quick sensor cleaning by opening sensor by hand without tool

Fertiliser Blockage Sensors

DSGR 4000i blockage sensors detect solid fertiliser flow continuity on precision planters, air drills or mechanic drills. Each optomodule possess an intelligent processor unit run by microcontroller. Linear connection and interchangeability make installation easy done in short time.

Sensor Features

  • Granular fertiliser flow/blockage detection (DSGR4000i)
  • Linear connection of sensors up to 128 rows
  • Calibration of expected fertiliser density
  • Available for air hoses with 25-35 mm diameter
  • Particle detection with 4 infras

*The minimum detectable object or particle size is depends on the objects or particles speed and the sensors optical elements dust status.

**Sensor cleaning is rarely due, thanks to Dust Detection & Compensation (DDC) function, so the operator can seed large areas without cleaning the sensors, allowing him to get the most out of the short seeding time at optimum conditions. The cleaning alarm is an unmatched solution to determine sensor dust level, then Dust Compensation, relying on dust test information, automatically compensate the sensibility. High sensitivity of blockage detection will be maintained by this solution. This solution is a Patented Technology by Digitroll.
