Understanding Your Seed Blockage Sensor Manual

When it comes to installing a seed blockage sensor you will need to have read and more importantly understood your manufacturer’s manual. Something which can be easier said than done. We aim to assist you in understanding your seed blockage sensor manual and if you have any further questions please get in touch with us.

Different Types of Sensor

There are several different types of sensors, this is something you are probably already aware of if you took the time to consider compatibility when choosing your seed blockage sensor. The types of sensors include:

Optical Sensor — detects blockage by measuring the change in light transmission or reflection as seeds pass through.

Capacitive Sensor — detects the presence of seeds by relying on changes in capacitance when a seed obstructs the sensor’s field.

Ultrasonic Sensor — detects by using sound waves, with differences in the time it takes for the sound wave to return indicating blockages.

With AS Communications, you can build your own bespoke seed blockage or seed counting package. They are made to fit any existing system requirements you might have!

Key Components

These include:

Sensing element — the part of the sensor reliable for detecting change (this is different for the different types of sensors).

Transducer — this is responsible for converting physical signals (like a change in light level) into an electrical signal.

Signal Processor — this processes the signal from the sensor and triggers the response.

Relay — this is a switch that opens or closes in response to the signal, this will normally trigger the alarm.

Controller interface — this is a connection point which is used to connect the sensor to a central control system

Operation Terminology:

Flow interruption — used to describe a situation in which the seed flow is temporarily interrupted due to blockage or air pressure issues

Threshold setting — the configuration of sensitivity levels or blockage thresholds that determine when the sensor will trigger an alert.

Calibration — the process of adjusting the sensor to accurately detect seed flow and blockage.

Sensitivity — this is a term used to describe how much of a variation it will take for the sensor to report a blockage.

Installation Terminology:

Mounting Bracket — the hardware used to attach the sensor securely to the planting equipment.

Power Supply — the electrical power source required for the sensor to work, this is likely to be specified with a specific voltage.

Sensor Alignment — make sure the sensor is correctly aligned with the seed flow path to accurately detect blockages.

Wiring Harness — a bundle of wires that connects the sensor to the central control or monitoring system.

Other Useful Bits of Terminology

Seed Flow Rate — the volume at which seeds are being dispensed from the planter.

Sensor Range — the maximum distance over which the sensor can detect a blockage.

Alarm Threshold — the level at which the system triggers an alert, indicating that the blockage has reached a critical level.

Status Light/ Indicator — a visual indicator that shows the current status of the seed flow, such as “OK” or less fortunately “Blocked”.

Active/ Inactive Mode — Describes whether the sensor is actively monitoring the seed flow or not.

Frequently Asked Questions on Seed Blockage Sensor Manuals

What should I do if I don’t understand technical terms within the manual?

Some manuals do include a glossary at the end which is a great way to find out what specific terms mean, but you can also read our list above. Although this is not an all-encompassing list this will put you on the right track to understanding the majority of any sensor manual!

Where can I find the correct manual for my specific sensor model?

Your seed blockage sensor will have a model number (on it or the packaging) and the manual will specify which model or models it applies to. If you are still unsure whether the manual is correct you can refer to the product serial number to help find the correct one. They can be found online, most manufacturers include digital copies of their manuals on their website.

Why are the seed blockage sensor manuals so long?

A seed blockage manual has lots of information to cover. They need to provide information on installation, troubleshooting, maintenance, safety and technical specifications. These sections individually are lengthy to ensure that you can properly set up and maintain your sensor. If you are looking for something specific think what category it fits under so that the manual is not so overwhelming.

What if I can’t find the information I am looking for?

This is unlikely due to how in-depth most manufacturers make their manuals, however, it is not impossible. A unique issue you are facing is unlikely to be covered in the manual and in this case, it is best to get in touch with the manufacturer for their advice. Another great option is to use online forums or groups of users of the same sensors.

When should I be referring to the manual?

It’s fair to say that referring to the manual is always beneficial, the most important times to refer to it are whenever you are installing, calibrating, troubleshooting or maintaining the sensor. Apart from this, the only other time you are likely to need to refer to the sensor is if you encounter and unfamiliar issue.
