Amplified (Digi-Pulse) Sensors                                  IS Digi-Pulse Sensor Brochure
Intrinsically Safe
 

Motion Sensors (MSI) intrinsically safe Digi-pulse sensors feature the same high quality construction and materials as our standard Digi-Pulse models. They are certified by CSA (with NRTL/C) and LCIE to ATEX (94/9/EC) for Class I, Zone 0, IIC and II 1 G EEx ia IIC T4, or Class I, Zone 0, IIA and II 1 G EEx ia IIA T4 hazardous locations.

Product Specifications

In addition to the models specified, MSI can make custom intrinsically safe Digi-Pulse 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 Digi-Pulse sensor for your application.
