Our Speed Sensors

Intrinsically Safe Speed Sensors
Certified to CSA, ATEX, and IECEx

MSI 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).

These sensors are intrinsically safe versions of Motion Sensors (MSI) Hermetically Sealed VR Sensors or Epoxy Encapsulated VR Sensors.
Motion Sensors (MSI) CSA, ATEX, and IECEx certified intrinsically safe RF (modulated carrier) models feature the same high quality construction, specifications, and features as our Standard RF sensors.
Intrinsically safe Digi-pulse sensors feature the same high quality construction and materials as our standard Digi-Pulse models.
Our Intrinsically Safe Hall Effect sensors feature the same high quality construction and materials as our standard Hall Effect speed sensors. They are designed and developed for each specific customer application.
Motion Sensors (MSI) PMX (variable reluctance) and PRX (RF) intrinsically safe preamplifiers offer features similar to our PA1001A preamplifiers / signal conditioners and can be used in hazardous environments with intrinsically safe Variable Reluctance VR or RF sensors (e.g., PC45-X or RF10-X, respectively).

It often happens that existing speed sensors are used in applications/environments that now require Intrinsic Safety. Identification and testing of an alternative, certified sensor can be time consuming and costly.

The Intrinsically Safe certifications at MSI (Motion Sensors) allow for customization of the sensor, providing the ability to design a fit, form and function equivalent to the legacy sensor. 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' Intrinsically Safe speed sensors are available in a wide range of technologies, including Variable Reluctance (VR), Active Sensors, Hall Effect, RF (Eddy Current), and stand-alone preamplifiers.
