Intrinsically Safe Tilt Sensors

Positek manufactures a selection of tilt sensors and inclinometers that are suitable for use in hazardous applications in gas, dust and mining environments


Our intrinsically safe tilt sensors operate on the basis of restricting the flow of electrical energy into a hazardous area. Any sparks that may therefore occur as the result of an electrical failure are insufficient to cause ignition, thus eliminating the threat of an explosion.

The intrinsically safe tilt position sensor is intended for use in hazardous or potentially explosive environments. For example, in construction environments where the production of combustible dust is likely, it is important any electronic components, such as the vehicle inclinometer that might be being used to measure the angle of a crane tilt, has attained the necessary safety certifications. The same would go for a truck inclinometer being used to transport coal in a mining environment.

Not only is our technology extremely robust, offering reliability that cannot be matched by an rvdt or similar technologies, every electronic tilt sensor that we supply has attained one or more of the following accreditations:

    •   IECEx approval
    • CSA approval
    • ATEX approvals.


Intrinsic safety is a concept that began in mining industries. Nowadays, it applies to any condition where the presence of hazardous airborne chemicals may induce explosions. To prevent such accidents from occurring, any device or part of a machine where electricity flows should not produce enough current to create sparks. Sensors used in hazardous conditions need to be intrinsically safe to pass standard requirements of safety.

How long do Positek’s intrinsically safe tilt sensors last?

Intrinsically safe sensors produced by Positek have specific fabrication intended for application in environments exposed to hazardous elements. Examples of these include mining, oil rigs, and chemical plants. Positek uses patented contactless technology making each sensor robust and durable. Intrinsically safe sensors can last years of use. These can withstand rigorous wear and tear and perform well even when submerged or exposed to noxious gas and vapour.

Can intrinsically safe tilt sensors be used indoors and outdoors?

Positek’s tilt sensors suit both indoor and outdoor commercial and industrial applications. For outdoor applications, you can choose a sensor according to the type of hazardous environment it will be exposed to. Moreover, intrinsically safe sensors manufactured by Positek complies with world standards of intrinsic safety. In the EU, the directive for intrinsic safety is ATEX, whereas for the rest of the world it is IECEx. All of Positek’s sensors have the necessary certification from these agencies ensuring that wherever the sensors are intended to for use, it complies with stringent requirements of safety.

What are the different types of intrinsically safe tilt sensors?

Tilt sensors measure the angle of displacement of an object concerning its original position. There are several types of intrinsically safe tilt sensors offered by Positek. You can select a sensor according to specific parameters such as:

Hazardous environment. Hazardous environment pertains to the exposure to dangerous elements such as gas, vapour, and dust. There are intrinsically safe tilt sensors specifically designed to work with intrinsically safe equipment in mining such as the M603 Large Angle tilt sensor that measures any tilt angle between 15° and 160°. Positek also has several tilt sensors intended for exposure to hazardous gas and vapour. Examples include the X603 Large Angle tilt sensor and G603 Large Angle tilt sensor. Positek also fabricates submersible intrinsically safe tilt sensors.

Intrinsic safety requirement. Intrinsic safety requirement varies by location. You can select from a list of intrinsically safe tilt sensors certified by ATEX, IECEx, and CSA.

Environmental sealing. Environmental sealing is another requirement when sensors are operating in hazardous conditions. For tilt sensors, Positek has IP67, and IP68 (350bar) environmentally sealed sensors.

Positek fabricates intrinsically safe tilt sensors for a variety of industrial uses. The dimensions of products in our current inventory can fit most applications. However, if none of our existing products fit your desired application, you can contact one of our dedicated engineers to help customise and design a tilt sensor for you. The customisation does not incur any additional cost, and we can assemble your custom sensor in our dedicated production facility with a fulfilment time of only a few days.


In order to comply with the above certification services, our tilt position sensor and inclinometer sensor solutions must be paired with a galvanically isolated three port amplifier.

If our standard tilt sensor dimensions are not suited to your application, please contact a member of our engineering team to discuss your specification. We can then design a custom tilt sensor at no extra cost to you, assemble it at our onsite production facility, and have it shipped out to you in a matter of days.
