Fertilizer Blockage Sensor

DSGR 4000i blockage sensors detect solid fertilizer 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.




Granulate Fertilizer Detection

Optomodules contain photosensors equipped with 4 infra lights and detect even the smallest granulate fertilizers like microgranulates.

Made by Long-Life Tested Material 

We are designed our sensors with long-life materials, they are Chemical, Oil, UV and Heat resistant.

Long Work Without Cleaning – Each Digitroll seed sensor is armored with DUST DETECTION & COMPENSATION (DDC) feature resulting long days and hours spent without sensor cleaning in the hassle of short seeding season. Increasingly stronger infra light is applied when infra surface becomes dusty or seed coating covered. Reaching a level, a ‘dusty seed sensor’ symbol appears on monitor screen following a push of the TEST button. This solution is a Patented Technology by Digitroll.

Sensor Features

  • Granular fertilizer flow/blockage detection
  • Detection and display of dust accumulation on seed sensor or blockage (DCD)*
  • For air drills/mech drills/planters up to 128 rows
  • Available for air hoses with 32 mm diameter
  • Particle detection with 4 infras
  • Durable Design

Seed-flow calibration has never been easier. Just one touch of a button and expected seed-flow with low rate alarm is on the right level. At any seed, at any speed. Slowly developing processes like lowering seed rates due to lowering seed level in hopper can also be observed, not only blockages.

• Sensor Type: Photocell
• Standard Sensing Objects: fertilizers (eg.: granular fertilizer, microgranulates)
• Minimum Detectable Object size*: 0.5-1 mm
• Maximum Speed of Detectable Objects: cca.20m/s
• Optical Detection Elements: 4-pair
• Detection proccess: Digital Signal Procession
• DDC – Dust Detection & Compensation**
• Cleaning Alarm: Automatic – send alerts if the sensor optics surface dust is too high**

  • Seed Master Integra
  • Calibra Flow

*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.

The DSGR 4000i sensors are official accessories of Vaderstad air drills. More information at www.vaderstad.com

Typical Applications & Benefits

• Combi air drills, where both seeds and fertilizers are applied at different rates
• Air drills having 64 + seeding rows
• Planters
