Intrinsically Safe RF Sensors
Certified to ATEX, IECEx, & CSA

Motion Sensors (MSI) CSA and ATEX certified intrinsically safe RF (modulated carrier) models feature the same high quality construction, specifications, and features as our Standard RF sensors. They are certified to CSA (with NRTL/C) and LCIE to ATEX (2014/34/EU) and IECEx for the hazardous locations listed below.

These sensors are certified intrinsically safe to:
  • CSA (with NRTL/C) for Class I, Groups A, B, C, D; Class II, Groups E, F, G; Class III
  • ATEX (2014/34/EU) for Ex II 1 G; Ex ia IIC or IIB T6 to T3 Ga
  • IECEx for Ex ia IIC or IIB T6 to T3 Ga



  • EC Declaration of Conformity and Installation Instructions
    ATEX Certification
    IECEx Certification
    CSA Certification


    Product Specifications

    In addition to the Standard RF sensors specified, MSI can make Intrinsically Safe RF sensors in other lengths, diameters, configurations, mounting threads (e.g., metric) as well as with different operating specifications and options like pigtail leads, NPT threads for explosion proof applications, etc. to satisfy special requirements. Our certifications permit us to make intrinsically safe versions of almost any MSI sensor, or to customize a sensor to suit a particular application or customer need.

    The customization process for Intrinsically Safe products at MSI is straightforward, quick, offers more choice, and is less costly than our competitors. Just tell us what you want and we will provide a fully certified custom intrinsically safe product in weeks, not months, made to your specifications, even if you only need one piece! This ability to provide rapid development of custom certified product without the normal certification costs and leadtimes is due to our unique "modular" certification scheme with CSA and ATEX. If you do not see a sensor that meets your needs please contact us to learn how Motion Sensors can provide a customized Intrinsically Safe RF sensor for your application.
