What Is an ATEX Sensor?

The use of technology in agriculture has greatly advanced in recent years, resulting in increased efficiency, improved yields, and reduced labor costs. One area where technological advancements have made a significant impact is in the use of sensors to monitor and control various aspects of farming operations. Among the latest innovations in this area are capacitive sensors, which have been approved by ATEX for use in agriculture; so-called ATEX sensors.

Understanding the ATEX Directive

ATEX (ATmosphères EXplosibles) is a European Union directive that sets out the requirements for equipment used in potentially explosive atmospheres. The directive aims to ensure that equipment used in such environments is designed and manufactured to prevent explosions and limit their impact on the surrounding area.

How Capacitive Sensors Work

Capacitive sensors are sensors that measures changes in capacitance, which is the ability of a material to store an electric charge. In agriculture, capacitive sensors are used for general detection of feed, grain, and solids among other things. A capacitive relay sensor is typically used as empty, full, and level indicator in tanks, silos, and containers during the emtying and filling process.

Why ATEX Approval Matters

ATEX approval of capacitive sensors for use in agriculture is significant because it means that these sensors meet the safety standards required for use in potentially explosive environments. This is particularly important in the case of installation where dust poses an imminent explosion risk classified according to Zone 20 and 21. Examples of this kind of environment could be in broiler houses or in flour production.

The Effect of Knowledge and Performance Management in Pig Production

Farm managers in pig production are keen to understand the dynamics of their operations: how are the pigs growing, what’s the rate of mortality, and other key performance indicators. Gaining control and insight into pig production can significantly enhance a farm’s efficiency, profitability, and overall success.

Being knowledgeable about various aspects of pig production — from breeding and feeding to health management and environmental control — is crucial for farm managers. This knowledge aids in improving animal welfare and, consequently, boosts productivity.

Improved Health and Welfare in Pig Production

A comprehensive understanding of pig health and behavior enables farm managers to quickly identify and resolve issues. This leads to healthier herds, lower mortality rates, and a reduced need for medical interventions, which can be expensive and sometimes harmful to the pigs’ health and the quality of the produce.

Higher Product Quality and Yield

Farm managers with a deeper understanding of their pigs’ performance can achieve higher product quality. This includes better meat texture and flavor, as well as more efficient reproduction rates. Such improvements are often the result of well-managed feeding programs, optimal living conditions, and strategies to reduce stress.

New research shows that pigs are far more socially aware than many people assume. When they want something, they actively try to get a human's attention -and they often use strategies similar to those seen in dogs. But unlike dogs, pigs tend to be a bit more self-reliant and selective in how they interact.

How Pigs Communicate with Humans

Research observed that pigs use a mix of vocalizations, body language, and direct eye contact when they want help or attention. They may nudge a person, stand in their line of sight, or repeatedly look back and forth between a human and an object - a behavior known from dogs trying to "show" their owners something.

A Key Difference from Dogs

While dogs have been bred for thousands of years to cooperate closely with humans, pigs have not undergone the same domestication process. This means pigs show attention-seeking behavior, but they don't rely on humans in the same way. They tend to switch strategies quickly and may try to solve the problem themselves if the human doesn't respond fast enough.
