Measure Position

Measure position need is the key to choose the right system. Depending by the application, the measure process can be performed on a single point, an area, or the entire strip, along both axis. Usually a single point scanning at the center of the strip is conventionally called "longitudinal scanning", instead a scanning along the width is normally called "cross profile scanning".  If the longitudinal scanning can be done just using a still frame because the strip is moving along the length,  cross profile scan must be done using a suitable solution.

  • Single point longitudinal scanning

The single point / centerline scanning at "strip/plate/slab center" is the simplest possible application, performing a thickness evaluation along the length of the strip, while the strip is moving. For this application 1 set of sensors is required, and a still frame is the minimum requirement. In some application, the systems can be mounted on existing structures, so it requires no frame at all.

  • Single point longitudinal scanning plus on demand cross profile scanning

Whenever a cross profile scanning is required, it's possible to add to the standard center-line an on demand cross profile scanning. In this case the application in quite similar to the single point scan, but with the possibility of move the sensors along the width, when the line is stopped. Just one set of sensors is required,and a frame with a bigger upper arm and throat depth may be applied. In this case, the entire frame will move along the width of the strip, providing a cross profile thickness trend. This option, even it is widely used because not expensive as the other solutions, requires a constant mechanical maintenance, and it is not preferred for very dirty environments.

  • Single point longitudinal scanning plus continuous cross profile scanning with moving sensors

Where a continuous scanning along the length and along the width is required, a solution with moving sensors can be applied. In number of 1 or 3 kit of sensors, depending by the acceptable sampling rate per millimeter and resolution, this solution is the best compromise between performances and costs;  a center-line, core and borders continuous scanning solution will combine the traditional longitudinal scanning and a very accurate cross profile scanning features, using a limited amount of moving sensors, covering all the width. By keeping the intermediate kit of sensors providing the center-line thickness for the automatic gauge control input active at any time, it will guarantee the AGC input with no interruption. Moreover, if the center-line kit would fail, will be possible to use the other sensors as center-line AGC input, simply positioning the side kit in the center. The continuous scanning along the width is 24/7 online.It can be equipped with a C shaped frame, or an O-Frame depending by maintenance preference.

  • Continuous cross profile scanning with still sensors

Commonly referred as "Instantaneous", it is a multi sensors system with no moving sensors. It uses the latest solid state PMT arrays in a variable number from 10 to 100, depending by the requested resolution providing the actual cross profile with no gap on the length side. That's the most important solution both in term of price and performances.

 

 

 

Measured Materials

Our systems find their natural application on steel and aluminum manufacturing lines, but can be used offline on discrete parts and on several materials such as plastics,rubber and ceramics.

In a thickness range from target of 7 microns (aluminum foil) up to target of 60 mm (hot steel plate), we can inspect and control your product's thickness online and no contact.

 

 

Frame options

Our frames are tailored to fit at best the application. We are capable to fit at best in existing spaces, by using different size of sensors. O-shaped, C-shaped, Inverted, on wheels, on slides, motor driven, pneumatic driven, moving or still. Starting from a small aluminum made 40 cm in height up to more than 3.5 meters  stainless steel, cooled jacket, we have the solution that fit at best Customer's requirements. Any questions? please don't hesitate to contact us.

Sensors

Digital sensors

Our sensors represent the state-of-the-art.  Digital and noise free, POE powered are made to stand the test of the time. Specifically designed to 24/7 work in harsh environment installations and extremely hard conditions, such as steel making hot strip mills and plate mills, their proven reliability makes them a something you can count on.

Software

Software you can trust

nGauge Core software is a stand-alone web-based application.

Simply connect and login any device using the standard Ethernet port, insert the core iP address and you will get the local HMI appearing on the screen. The nGauge core software is capable to manage the IOs as well as the human machinery interface, The HMI is independent from the IO's and sensors management, so it can works stand-alone without any visualization device connected.

DBSolution is a SQL Server based application which allow operators to have available, in real time and during the actual roll the thickness, speed and vibration at the same position from the previous line. For example, the trend acquired during the tandem mill is available in the recoiling line.
