About Curtiss-Wright Round Rock
Curtiss-Wright Round Rock designs and manufactures temperature sensors, pressure transmitters and fiber-optic signal products in Round Rock, Texas, for aerospace, nuclear power and industrial customers. Founded in 1968 as Weed Instrument Co., the business became Ultra Electronics Nuclear Sensors & Process Instrumentation (NSPI) after a 2008 acquisition and joined Curtiss-Wright Corporation on December 31, 2024, as part of its Nuclear Division.
What Curtiss-Wright Round Rock makes
Aerospace temperature sensing. Round Rock winds its own platinum and nickel RTD elements, which lets it produce non-standard resistance curves. Those elements go into rugged immersion probes, surface sensors, air temperature sensors and Ultra-Cryo cryogenic sensors that monitor bleed air, cabin air, engine oil, fuel, hydraulic fluid and compressor discharge on commercial and military aircraft and reusable launch vehicles.
Nuclear-qualified temperature and pressure. RTDs, thermocouples and transmitters are qualified to IEEE 323 and IEEE 344 for Class 1E service across PWR, BWR, CANDU and other reactor types, including small modular reactors. The company reports that its temperature sensors are used for reactor coolant monitoring in more than 80% of US reactors, and its pressure transmitters in more than 20% of US plants. The DTC3 and DTN2070 transmitters give plants replacement paths for obsolete Rosemount and Foxboro instruments.
Fiber-optic products. Nuclear-qualified analog converters such as the N9487 and N9488 isolate safety and non-safety signals, while EOTec 2000 Ethernet switches and MX multiplexers carry industrial data across wide temperature ranges and in hazardous areas.
Why engineers specify Curtiss-Wright Round Rock
- Qualification depth. Quality programs include AS9100D, ISO 9001:2015, ASME NQA-1:2015, ISO 19443 and CSA N299, backed by LOCA testing and RCC-E qualification for European designs.
- Aerospace credentials. Round Rock is an FAA PMA supplier of aerospace temperature sensors.
- Obsolescence solutions. Engineer-to-order designs, commercial grade dedication and equipment qualification services support plant life extension.
- Accredited calibration. An A2LA-accredited ISO/IEC 17025 laboratory calibrates RTDs and thermocouples.
Local support from Vaughn Associates
The Southeast is home to Huntsville’s aerospace, missile and space programs, commercial nuclear plants in several states and Gulf Coast process facilities. Vaughn Associates helps engineers in each of these communities define sensor type, element, curve, qualification and documentation requirements before a quote is requested.
We coordinate quotes and technical questions with the Round Rock factory and follow each order through delivery. Vaughn covers Curtiss-Wright Round Rock in all of its territories.
