Intrinsically Safe Speed Sensors

Motion Sensors intrinsically safe sensors are certified for use in both North America and Europe to the most stringent requirements. These speed sensors are certified intrinsically safe to CSA (with NRTL/C), ATEX (2014/34/EU), and IECEx (IEC 60079-0:2011 and IEC 60079-11:2011).

CUSTOM MODELS

In addition to our standard models, Intrinsically Safe speed sensors are available in custom lengths, diameters, configurations, and mounting threads. Custom operating specifications (output options, etc.) are available, as well as options such as pigtail leads or NPT threading. See additional sensor customization options.
