Our Speed Sensors

Explosion Proof (Ex d Certified) Sensors

MSI explosion proof sensors are Ex d certified to ATEX and IECEx and comply with the essential health and safety requirements relating to the design and construction of equipment and protective systems intended for use in potentially explosive atmospheres.

These sensors are Explosion Proof (Ex d certified) versions of Motion Sensors VR Sensors. A wide variety of functional and physical characteristics are available, such as different pole piece diameters, resistance ranges, and mounding thread options.
Motion Sensors' IECEx and ATEX certified Explosion Proof (Ex d) RF (modulated carrier) models feature the same high quality construction, specifications, and features as our Standard RF sensors.
Explosion Proof (Ex d certified) Active sensors feature the same high quality construction and materials as our standard Digi-Pulse models, based upon either variable reluctance or RF technology.
Our Explosion Proof (Ex d certified) Hall Effect sensors offer several types of hall effect zero speed options in a flameproof housing, including oriented, non-oriented, and quadrature output models.

The Explosion Proof certifications at Motion Sensors allow for customization of the sensor, providing the ability to incorporate a wide range of threading, dimensional, and functional options within the existing Ex d certified product line. Since the customization process does not require additional certification testing, custom sensors can be provided for applications that require one unit up to thousands of units; with lead-times of weeks versus months.

Motion Sensors' Explosion Proof speed sensors are available in a wide range of technologies, including Variable Reluctance (VR), Active Sensors, Hall Effect, and RF (Eddy Current).
