Applications

GadCap CapaciSense will once again be exhibiting at the ASME Turbo Expo.

Come and visit us at booth #506.

You can see a demonstration our our equipment and our exciting latest product developments, as well as discuss any technical questions you may have.

If you would like a visitors pass or wish to book some time to discuss your application in detail please contact us.

Thank you to those who came and saw us at Turbo Expo 2015.

ASME TURBO EXPO 2015

Hopefully you found our demonstration of CapaciSense SOLO informative. We really believe that by adding this unit to our blade monitoring solutions we have further expanded the possibilities for customers to take advantage of this technology.

Please get in touch if you have any questions about our systems – we are here to provide a complete solution so can design the full package for you.

For those who missed us, come and see us at the EVI-GTI event in November.

Come and visit us at booth 617 at the Turbo Expo 2015 in Montreal, Canada, June 16-18.

You can see a demonstration our our equipment and our exciting latest product developments, as well as discuss any technical questions you may have.

If you would like a visitors pass or wish to book some time to discuss your application in detail please contact us.

PTM’s stand at the ASME Turbo Expo 2014

Thank you to all of our customers who came to visit our stand at Turbo Expo 2014 and helped to make the event a big success.

“The new Pentair stand banner proved quite an eye catcher with the visitors and was enhanced with the portable demonstration rig which shows real time monitoring data from our system. A good number of potential projects were gained from the show “, said Arthur Harrison the GadCap CapaciSense salesman.

We look forward to attending Turbo Expo 2015 in Montreal.

We are pleased to announce that their CapaciSense blade monitoring team will begin to offer Optical based solutions in addition to their traditional Capacitive based systems. This is as a result of our collaborating with Prime Photonics.

“We have for some time worked with EDAS with their software solution to provide tip timing and we have always acknowledged that our Capacitive based systems whilst being excellent for long duration testing and in-service use we recognise that optical systems have their place. We therefore have decided to work with Prime Photonics to offer an optical system which is better suited to engine characterisation testing. It is hoped that the 3 companies working together with their individual strengths will provide a complete solution to all customers no matter their application.” Says Paul Seccombe.

If you would like to enquire about either a Capacitive or Optical based blade monitoring system for Tip Timing (NSMS) or Tip Clearance please see the Capacisense website www.capacisense.com.

The new CapaciSense website launched in February 2013. Please visit it over the coming months as more content will be added. Don’t forget to request a user login so you can get access to additional files and support material.

If you are involved in tip clearance measurement in any way you might want to take part in ISA107.3 the working group created to write a standard for this measurement. The team is Chaired by CapaciSense’s Paul Seccombe and official contact can be made directly with Paul or via the ISA website.

Gas Turbine blade clearance monitoring

Our sensors can be used at extremes of temperature so gas turbine blade clearance monitoring can be carried out even in the highest temperature zones of the turbine.

This means the whole engine can be monitored, not just the lower temperature compressor areas. This raises the possibility of controlling the various stages differentially and optimising the whole turbine rather than just one zone.

Turbine fuel efficiency is directly affected by the size of the clearance, so designers and manufacturers are using the live outputs to adjust clearances to a minimum on working turbines. This provides turbine operators a way to gain greater fuel efficiencies.

By providing real time data, you will access early warning signals of potential problems, which will help you to make decisions and avoid unplanned and expensive outages or even catastrophic failure. Turbines are extremely sensitive to blade tip rubbing, which can be the cause of failure. Our tip clearance functionality will monitor differential thermal growth during warm restarts, and the information provided helps you to prevent tip damage caused by blade rubbing. Our tip timing functionality will monitor the arrival time of a blade tip and use this to calculate blade deflections and identify vibration.

ATEX hazardous area approval for gas turbine sensors

We recently secured European ATEX approvals for the system and are soon to add North American FM & Asian TIIS Approvals. This means that the systems can now be used in hazardous areas – such as operating power stations.

For those retrofitting turbines with additional condition monitoring sensors that means you are now able to fit them in operating turbines – for use in predictive maintenance or to check blades in “near rubbing” conditions.

Our capacitive blade tip clearance systems are now ready to be used in the hazardous area zones of some of the world’s largest power generating gas turbines for long term condition monitoring. Our systems are used for high temperature turbine sensing at up to 1400°C.

UPDATE: 2008: In one case, the lifetime of the probes exceeded 10.000 hours of continuous operation. Probes returned after that time following routine refurbishment at outage are still in working order.
