Hazardous Area Sensor Solutions
Monitor conditions across potentially explosive atmospheres.
We supply IECEx certified sensors for use within hazardous areas. Explore products and potential applications below, or get in touch and we will help source the right sensor variant for you.
Before the order, we check it is safe to specify.
Keep an eye on your operations
Using IECEx certified sensors, you can accurately perform position and object detection, distance and level measurement across your plant, no matter the zone rating.
Keeping an eye on equipment condition is critical. Hazardous areas within petrochemical plants, grain elevators, feed mills and mine sites should not be black spots for condition monitoring.
Record vibration and temperature levels from motors, pumps and critical equipment with certified wireless condition monitoring sensors. Harness valuable insights from hard-to-access zones and make predictive decisions on maintenance scheduling.
Our team is on hand to assist you with sensor selection and suitability for hazardous area applications.
It starts before the order
Three questions we ask alongside the part number, so the sensor you specify is certified for the area it goes into.
Where does it run?
Zone rating, temperature, humidity and condensation, washdown, dust, sand or grease, and whether the point is hard to access.
What is it doing?
Object detection, level measurement, position feedback or condition monitoring. The target material, ferrous or not.
What if it is wrong?
Ignition risk, a missed detection, a failed bearing nobody saw coming, audit exposure, a line down now.
The sensing technologies we supply
Inductive, capacitive, linear and wireless, selected against the zone and the material you are detecting.
Inductive sensors for hazardous areas
Inductive sensors detect using a magnetic field. They are used to detect ferrous materials. This touchless technology results in a mechanical lifespan that is technically unlimited.
Accordingly, inductive sensors are a robust solution for harsh industrial applications involving high temperatures, humidity and condensation, and contaminants including sand or grease.
Inductive sensors within hazardous areas can cover metalliferous mining operations and materials handling conveyor belts. Protection methods including encapsulation will cover lesser rated zones, while intrinsically safe sensors are available for higher rated applications.
Inductive SensorsCapacitive sensors for hazardous areas
Capacitive sensors are switches that have no moving parts. They measure using an electric field and can also detect non-ferrous materials and metals.
Capacitive sensors can be found within hazardous areas covering handling applications within the coal, sugar, grain and pharmaceutical industries. This can include level monitoring of solids including powders and granulates, adhesive liquids including oil and glues, and object position detection.
Both barrel and probe-style capacitive sensors can be supplied on request. Intrinsically safe capacitive sensors used in conjunction with intrinsic safety barriers are suitable for specific applications within zones 0 and 20. Sensors with FDA and EHEDG certification are available for food production applications.
Capacitive SensorsIECEx certified linear transducers
Linear transducers are position sensors. They measure movement along a single axis in any direction. The sensor converts the movement into an electrical signal, which is proportional to the displacement.
Linear transducers are available in various sizes to suit long range applications or applications where space is restricted. Common applications within hazardous areas include monitoring hydraulic or pneumatic cylinders.
Measurement & EvaluationIECEx certified wireless sensors for predictive maintenance
Are you servicing pumps and motors on regular intervals, or only once they have failed? If so, it is time to consider a change. Predictive maintenance collects data from multiple points across your operations. Vibration and temperature levels from pumps, motors and conveyor belts are typical examples.
Wireless IoT sensors can be easily integrated with existing infrastructure and equipment. Many of these sensors utilise LoRaWAN, a low power, wide area network technology capable of spanning up to 10km in ideal scenarios.
The Advantech WISE-2410x is designed for condition monitoring and is fully IECEx certified. Use it to monitor temperature and vibration levels, and start performing maintenance on an as-required basis. Pull actionable information from the plant floor and into your hands.

Wireless solution for a major grain terminal
We have recently begun implementing a LoRaWAN sensor solution for a major grain handling terminal in Western Australia. The site accounts for over fifty percent of state exports.
Using the Advantech WISE-2410x sensor together with WISE-6610 gateways, we have significantly cut down on infrastructure requirements. These sensors are battery powered, and each gateway can manage up to 500 sensors. This makes installation faster, and cheaper to implement.
Once complete, this condition monitoring solution will provide real-time updates on critical machinery, and give early indications of pending equipment failure.
