Delta Controls offers a comprehensive range of qualified and tested pressure, temperature and flow measuring instruments for the nuclear industry.

Nuclear New Build

Delta has been designing and manufacturing instrumentation for the power and process industries for over 65 years and has served the nuclear industry in the UK since the first nuclear reactors were designed and built over 55 years ago.  

A specialist in pressure, temperature and flow sensors, Delta has provided a range of generic and bespoke instruments to the industry across all the UK Nuclear Fleet including Magnox, AGR, PWR and DFR and PFR.

Delta has also worked in the worldwide nuclear industry for over 40 years with projects in China, Sweden, Finland, South Korea, the USA, Canada, India and Spain on PWR, BWR and CANDU reactor types. Our products are used within containment, in the nuclear island, in safety shut down applications, critical areas of process control, alarm and general process monitoring. 


Delta has also worked extensively on decommissioning projects, fuel processing and reprocessing, working with Sellafield (formerly BNFL), Westinghouse and the UKAEA.  

Product Qualification

Instrumentation used in Nuclear Power Plant may be required to survive seismic and radiation exposure of different severity levels depending on the location in the plant and the application. Delta’s products meet the RCC-E and  IEEE Class 1E requirements for seismic and radiation endurance. Tests details are available and are also summarised in the Instrumentation for Nuclear Applications Brochure available as a download here. Many products also meet SIL 2 requirements and numerous international Hazardous Area approvals. 

Conventional Island

Also, through our work on the Conventional Island including the Turbine Hall and other major systems, Delta has worked with all the major equipment suppliers to provide the critical safety and performance related products, protecting investment and the environment.

Bespoke products

We have also developed bespoke products for our customers whenever a technical solution cannot readily be found ‘off the shelf’. Our team of Engineers is ready to discuss your exact requirements to ensure the product you need for your application is correctly specified and supplied.
