DRS-CCI - Pressure and Differential Pressure Transmitters
The DRS Consolidated Controls Pressure and Differential Pressure Transmitters are designed for Class 1E safety related nuclear applications. The basic design is that of a Bellows/LVDT construction which DRS Consolidated Controls has over 50 years experience with units delivering reliable service in nuclear applications. DRS Consolidated Controls manufactures a broad line of transmitters and sensors to monitor pressure, flow, level, temperature, speed and position for severe environment applications.
Commercial Sensors and Transmitters
DRS-CCI has a long history of providing Instrumentation and Control equipment for numerous applications. DRS-CCI has designed, qualified and manufactured components and systems for some of the most critical control applications around the world. DRS-CCI sensors and transmitters are designed and qualified to operate in extremely adverse environmental conditions encountered in both primary and secondary plant applications. DRS-CCI sensors and transmitters are highly accurate and will operate continuously for decades in critical applications. Longer life corresponds directly to lower overall operating costs through the elimination or reduction of periodic transmitter replacement due to high temperature or radiation degradation over the life of the plant.
Highlights
- Custom application-specific models to suit the harshest needs
- Replace legacy transmitters that are no longer available
- Design into Advanced Reactor Applications to yield unmatched performance that can’t be satisfied with currently available transmitters
- Over 50 years of experience producing extremely rugged units for pressure, differential pressure, position, and temperature
