Sensors for generators and large motors

Stator Winding RTD

Our DynaWind Sentinel RTDs, developed in collaboration with the C2Mi and the CRIQ, are the epitome of high reliability in temperature monitoring for large motors and generator windings with advanced features to detect hotspots and ensure the safe operation of critical equipment. The collaboration between our organizations guarantees innovation and an ongoing commitment to reliability.

Recognized by the National Electrical Manufacturers Association (NEMA), these flat, laminated “stick” RTDs provide continuous temperature sensing for early warnings when needed. When reliability is paramount, our DynaWind Sentinel RTDs stand out as the only solid choice. We know that dependable sensors are a non-negotiable asset, particularly in critical applications. When the stakes are high, you can rely on our product to ensure the longevity and safety of your motors and generators. DynaWind Sentinel RTDs, when reliability matters!
