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.
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.
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.
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 use of ATEX-approved capacitive sensors in agriculture can help to improve the accuracy and efficiency of farming operations. By providing precise and reliable measurements of various parameters, such as the level of feed in a silo or the moisture content of grain, these sensors can help farmers to optimize their production processes and reduce waste.
For example, by using capacitive sensors to monitor the level of feed in a silo, farmers can ensure that their animals are fed on a regular schedule without overfilling the silo or allowing it to run empty. This can help to reduce feed costs and improve animal health and productivity.
iDOL 46 ATEX approved Capacitive Sensor is specially designed for agricultural purposes.
In addition to their use in agriculture, ATEX-approved capacitive sensors are also used in a wide range of other industries, including chemical processing, oil and gas, and mining. In these industries, these sensors are used to monitor and control various processes in potentially explosive environments, such as the filling and emptying of tanks, the mixing of chemicals, and the processing of flammable materials.
In agriculture and industrial facilities there are several applications where explosive atmospheres may be present, making ATEX sensors indispensable. For example, in facilities that store and handle grain, grain dust, which is a potential source of explosion, is often encountered. ATEX sensors in these environments are crucial for monitoring and controlling the filling and emptying of grains, ensuring safe operation in silos, conveyors, and processing units.
