Scantech quality and control systems (QCS) are manufactured with open architecture and modular equipments or devices that communicate through an Ethernet TCP / IP network.
“Open” means that Scantech equipments are designed to freely communicate with customer computers and systems.
Scantech concept of modularity is based on the following three (3) main characteristics:
1. The equipment must be independent and self-sufficient. This means that it completely fulfills the task for which it’s been designed to perform.
2. The equipment modules can flexibly be assembled in the order that achieves the best configuration that suits the customer’s application.
3. The equipment itself is designed in a modular fashion.

3. The equipment itself is designed in a modular fashion.
Independence and self-sufficiency:
This is a very stringent requirement because it sets a specific task to each device. This implies that each device is equipped with its own intelligence (computer). It also minimizes external wiring, that is to say, there are only power and network connections. Examples:
The scanner’s function is to measure. It must therefore produce accurate measurements by itself, with the correct physical units, useable by other QCS equipments, or by the customer.
The control system function is to compute set-points and to apply them.
The function of an operator interface is to drive a QCS system. It must therefore display measurement data, accept commands, display status and reports. But in no case, be involved in the manufacturing process or in the measurement computations.

Assembly of the modules:
The Scanners, Control Systems, and User Interfaces must be able to be assembled in any quantity for different network topologies.
Equipment Modularity:
The equipments themselves must be designed as an assembly of sub-modules in order to achieve a high level of standardization.
Openness:
Each device must be equipped with configurable communication ports and also be able to support major market standards for the data exchange such as OPC.
These aforementioned qualities provide Scantech customers with very important benefits:
Reliability: Is the result of the high level of standardization.
Ease of maintenance: In addition to component standardization, it is a direct result of the segmentation and distribution of tasks.
Reduction of spare parts stock.
Scalability: Our approach allows easily the addition of new equipment to any initial configuration.
Long term sustainability: Is also a direct consequence of the modularity of the equipment.

Scantech offers three main types of equipment:
1. Scanners, whose task is to provide the necessary measurement data needed to control the manufacturing process and to determine the quality of produced materials.
2. Control Systems, whose function is to drive the manufacturing line so that the production parameters measured are within the customer defined tolerances of quality.
3. User Interfaces (such as operators, production supervisor, maintenance staff or quality manager… ) drive the scanners and control systems (commands, parameters, status…) and display quality parameters in real time. They also provide statistical processing, reporting, and archiving amongst a lot of other functions.

A scanner or a gauge is a measurement system typically located on a production line. Its function is to characterize the main parameters of flat materials during their manufacturing process which consequently allows to control the line.
There are three possible modes of operation:
1. Manual Control: It is performed by the operator.
2. Automatic Customer Control: The scanner transmits data to the customer’s control system.
3. Automatic Scantech Control: The manufacturing process is controlled by Scantech’s equipments.
2. Automatic Customer Control: The scanner transmits data to the customer’s control system.
3. Automatic Scantech Control: The manufacturing process is controlled by Scantech’s equipments.
The scanners consist of three main modules combined to meet the requirements of the customer’s application:
1. The Mechanical frames: They are adapted to the width of the material to be measured, to the constraints of space, to the environmental conditions and to the type of measurement needed.
2. The Control System which defines the internal electronic, network and software architecture of the scanners. It includes also the necessary electrical equipment.
3. The Sensors which are selected in order to provide the best measurement solution for each application. From a network and software point of view, scanners can handle any number of sensors, but available space constraints on the production line along with actual customer requirements normally limit the quantity to three or possibly four.

From a network and software point of view, scanners can handle any number of sensors, but available space constraints on the production line along with actual customer requirements normally limit the quantity to three or possibly four.
The scanners operate in scanning mode or in fixed point position.
In scanning mode, the material is measured along its full width (including edges) in a constant back and forth pattern. The measured path, taking into account the material movement, is shown in the figure on the left.
In almost all cases, the corresponding statistical sampling is more than enough to correctly characterize the measured quality parameters.
In “fixed point” mode, the sensor(s) is placed at a specific point across the width of the material to be measured. It only provides measurements in the production direction (machine direction).
This mode is best used when the cross profile is not very important and mainly when the process control response time in the machine direction needs to be very fast.
Mechanical frames are selected according to the material width, the type of measurement to be performed and the environmental constraints.
O-Shape Frames
“O” shaped frames are used to guide and move sensors, whose heads are located under and above the material to be measured, in a continuous back and forth pattern.
O Frames have two advantages:
Their transverse space is reduced to the line width and does not overstep too much on the side lines.
They can be manufactured in very wide widths (ten meters and even more).
They can be manufactured in very wide widths (ten meters and even more).
But, they also have a drawback: since the sensors consist of two independent parts, typically a transmitting head and a receiving head, both moved synchronously and hence subject to variations of their alignment that may impact the measurement if the sensors design has not been thoroughly thought off.
Scantech offers four model ranges of O-shape Frames:
1. The LO1 range consists of lightweight and economic frames for measuring materials up to 4000 mm wide with all types of sensors.
2. The MO1range covers intermediate widths from 4500 to 7000 mm.
3. The HO1range is extremely robust and designed for very wide materials, for clean room environments or inversely for very harsh environments. 
2. The MO1range covers intermediate widths from 4500 to 7000 mm.
3. The HO1range is extremely robust and designed for very wide materials, for clean room environments or inversely for very harsh environments.
C-Shape Frames
“C” shaped Frames have a perfect geometry since transmitters and receivers have a fixed relative position. The sensors are mounted in the arms of the “C” – shaped Frame and the complete frame is continuously moved back and forth transversally across the measured material. The disadvantages are that the maximum product width that can be measured is 2.5 / 3 meters, and that sufficient space (one frame length) must be available on one side of the production line for frame travel.

C Frames are commonly used for optical sensors applications in order to optimize the measurement precision and they are also a suitable solution for applications where there is little space in the machine or vertical directions.
C Frames are essential if the application requires the complete removal of the scanner from the production line.

Scantech offers four “C” Frame model ranges:
1. The LCI1 range with sensors embedded in the C Frame arms can be used for applications with air gaps (distance between the arms) up to 700 mm. They can be installed in spaces as narrow as 200mm in the machine direction.
2. The MCI1 range with sensors embedded in the C Frame arms can be used for applications with air gaps up to 700 mm too. But the lower arm cross section is larger (250x300mm).
3. The HCI1 range with has also sensors embedded in the C Frame arms. HCI1 frames have an extremely strong structure suitable for hot or even very hot environment. The arm cross section is 400mm and the air gap can reach 4000mm.
4. The LCO1 range has external sensors fixed on the arms and not located inside the arms. The air gap is limited up to 200mm.

In the majority of the cases, SCANTECH standard models meet customer application requirements. However, sometimes, requirements such as space constraints or other special installation criteria do not match with our standards.
Please do not hesitate to indicate to us your needs. Scantech applications design office will quickly study and respond to your requirements with a proposed mechanical solution, specifically tailored to meet your application’s needs.
The System is the scanner’s electronic architecture, network, and software.
Scantech offers two different types of systems:
1. SSA1: This system is suitable for simple configurations where the scanner has a limited number of inputs and outputs. A single sensor can be supported. The internal network has a fixed configuration and operates at a speed of 1Mbits/sec.
2. SSA2: This system is dedicated to more complex applications. It is built around a chain of microprocessors communicating through a deterministic high-speed bus (100Mbits/sec). This topology allows various configurations of input and output capacities and supports multiple sensors, their number being limited by mechanical or space consideration and constraints.

This topology allows various configurations of input and output capacities and supports multiple sensors, their number being limited by mechanical or space consideration and constraints.
Both systems allow the scanner to communicate with any number of other equipment (other scanners, control systems and user interfaces).
Both systems, and especially SSA2, are extremely advanced and have no equivalent on the market. For example, the sensors are systematically equipped with their own intelligence. Scantech has been developing and offering this concept for twenty years and has become the most experienced supplier in the field.
There are many types of sensors for online measurement and they can be classified into two (2) families:
1. Sensors that contact the measured material
2. Non-contact sensors
2. Non-contact sensors
Scantech offers only the latter category: non-contact sensors. These sensors satisfy the vast majority of applications by means of the following four (4) technologies:
1. X-ray Sensors: Scantech is the leader in this technology and was the first to introduce in 1992 an x-ray sensor for the thickness measurement of plastic films and in 1993 for the weight of non-woven materials.
X-ray sensors are used, almost exclusively, for the measurement of the thickness of metal sheet.
2. Infrared Sensors: Scantech systematically uses these type of sensors to measure the thickness of barrier layers of multi-layer films, and often use them for the measurement of coating weights and humidity.
3. Beta Radiation Sensors: It is a technology that Scantech offers as a last resort when it is the best compromise for the measurement of thickness or weight. Beta sensors use a radioactive source which causes more and more difficulties for customers regarding legal compliances.
4. Laser Triangulation Sensors: Scantech has developed its own proprietary design. This sensor is used for measuring the thickness of inhomogeneous materials (i.e. variable density, layers of very different nature, foam…). Theses sensors can also quantify the material surface such as roughness.

Different types of sensors can be coupled on the same scanner in order to achieve other measurements. For example, an X-ray sensor coupled with a Laser triangulation sensor can measure the density of a material.
All Scantech sensors are interfaced through the internal scanner bus and possess a local intelligence allowing the direct digitization of the sensor signals and the pre-processing of measurements.
