NSPI has been supplying nuclear qualified temperature sensors, thermowells and transmitters, pressure transmitters and fiber optic modems for more than three decades. NSPI is recognized as a global leader in the technologies we supply, in part because of our intense focus on quality and reliability.

Today, over 80% of all North American reactors rely exclusively on NSPI temperature sensors for critical reactor coolant monitoring. NSPI’s nuclear qualified pressure transmitters are used for safety related and BOP measurements at over 20% of US nuclear power plants. NSPI products have been qualified for use in all of the leading reactor technologies, including PWR, BWR, CANDU (PHWR), and APWR.
