Power Generation – Thermocouples and RTD’s


Power Station

The Power Generation sector, as with most of the sectors we work with, is one of the most demanding environments to work in. And it certainly requires outstanding levels of accuracy and reliability when it comes to the ability to measure temperature within its processes and applications.


Added to that, there are also challenges to be faced by the Power generation sector over the coming decades as the industry faces up to massive increases in usage, by 2030 electricity use will double globally and triple in developing countries.

With these massive demands facing the industry it is imperative that Power Generation facilities are more reliable than ever to enable them to create the electricity that will be required in the coming years. At Okazaki, our engineers have developed a range of products that are designed for long life as well as giving the highest level of accuracy in their results.

Our expertise in the Power Generation sector is Temperature and Pressure Measurement units, Cabling and Electric Heaters. And we can offer products for many applications whether that be in Coal, Gas, Nuclear, Hydro Power, Gas Turbine Plants and Thermal Power Stations to mention a few.

For the benefit of this article, I wanted to talk about two products, Thermocouple Assemblies and Resistance Temperature Detectors (RTD’s).

As with all our products our Thermocouples and RTD’s have been extensively and rigorously tested to ensure they can meet severe demands that will be placed on them. They also meet several safety standards around the world.


A thermocouple connects both ends of two different types of metal wires. When a temperature difference occurs between the contacts at both ends, a thermoelectromotive force is generated in this closed circuit and current flows through the circuit. The magnitude of this thermoelectromotive force and its polarity are determined by the temperature at both ends and the combination of the two metal wires, and are not affected by the thickness or length of the metal wires. Therefore, it is possible to measure the temperature by knowing the thermoelectromotive force at each temperature of a specific thermocouple in advance.

Our range of Thermocouple Assemblies which include, Tubeskin Thermocouples (Fantype and Aeropad) and Multipoint Temperature Assemblies have been designed to eliminate temperature measurement problems that happen within the Power generation industry.

Any problems arising from flame impingement, heat sink effects and radiant heat can be dealt with as quickly and effectively as possible. Truly accurate and reliable temperature measurement will improve your furnace operation and consequently increasing your throughput.

Resistance Temperature Detectors (RTD)

Our RTD sensors are designed and manufactured to operate over the extreme temperature range of -260℃ to +930℃.

Compared to conventional resistance temperature detectors, the conductors and resistance elements of our sheath RTD’s are insulated with a chemically stable magnesium oxide to maintain airtightness, so they have a longer life against aging and disconnection. 

These sensors offer excellent performance across this wide temperature range giving High Accuracy with fast Thermal Response, with no effect from High Vibration, Mechanical shock, and adverse radiation levels.

If you’d like to discuss any of our products with our team you can call us on 029 2081 4333 or email on sales@okazaki-mfg.co.uk.

Hydrogen On-Line Conference 2021


On Friday 8th October we will attending the Hydrogen On-Line Conference 2021.

We will be promoting our products for the Hydrogen and Fuel Cells industry, our poster will be on show throughout the day.

We are also excited to hear what the speakers have to discuss in this very exciting sector.

Brining Innovative Solutions to the Toughest Challenges

Innovation not Imitation


Recognising the increasing challenges that our clients face, we are proud of the work that our engineers do to bring the latest technological advances to our cabling, heating and temperature measurement solutions. 


Our clients work across the globe in some of the most challenging environments there are and here are a few examples of Solutions we have provided which provide greater stability and more accurate readings.


When it comes to a hydrocracker or hydrotreater unit, our range of specialist multi-point assemblies enable a full 3D temperature profile to be carried out.  We’re also able to offer a unique supply chain solution using our AeroPak mineral insulated cable and laser-welded systems.


An area of particular concern for fluid catalytic cracking units is the harsh operating conditions that they need to work in.  This where our advanced temperature measurement solutions are highly effective.  Clients can choose either our dip-leg or catalyst cooling measurement solutions.  For highly abrasive process conditions, we also have specially coated thermowells that have the ability to operate in such environments.


For the actual catalytic process, we’re fully aware of space being limited, consequently we’ve developed a range of miniature specialist temperature assemblies using our AeroPak mineral insulated cable.  This includes the AeroMini, with an OD of 3mm, it has multiple individual measuring points found on its length.


Other locations where extreme temperatures are also a major factor for consideration include sulphur recovery units.  These are widely recognised for having a harsh process temperature. Our products are frequently chosen due to their ability to ensure the safe and efficient operation of these units.  Storage tanks are certainly another area where there’s great demand for temperature assemblies. 


Cryogenic applications such as LNG storage require an extremely high level of accuracy, and over the years we’ve worked hard to develop the design of our temperature assemblies to meet these demands.  We’re able to supply our RTD or thermocouple assemblies with extended lengths using our patented AeroPak mineral insulated cable.


If you’d like to discuss any of the above or learn about other products contact the team on 029 2081 4333 or sales@okazaki-mfg.co.uk.
