Temperature Switch


Fast Response


Fast reaction air temperature switches are used throughout a nuclear power plant to detect sudden rises in ambient temperature. Delta has optimised the design of this product to react very quickly to temperature change and can

provide fast early warning of possible

problems in the plant.

This model consists of a sensing element manufactured from thin walled copper tube

Filled with a volatile fluid.

By keeping the length to diameter ratio

High the surface area of the sensing

Element is maximised achieving a

Faster response to temperature

Changes than more traditional types.

Differential Pressure Switch

Special engineered differential Pressure switch incorporating chemical

seals with flushing ports and small deadband

Delta’s  team of Engineers are ready to discuss your exact

 requirements to ensure the product you need for your

 application is correctly specified and supplied

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.



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.

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.

Industries

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.

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.

Fit For Nuclear Companies

These companies have been granted Fit For Nuclear status by the Nuclear AMRC.

They have benchmarked their performance against the standards demanded by the

nuclear industry’s top tiers, and driven business improvements

through a tailored action plan

Delta Controls has completed the Fit 4 Nuclear programme run by the NAMRC, to see more - click here
