Proscan MasterTrak Overview

Proscan MasterTrak - a complete online thickness or width measurement and control system 

Using a non-contact measurement technique to measure the thickness or width profile of continuous or piece products as they are being produced. When used to measure thickness, the system can be supplied either to measure single or multiple points across the width of the product. The MasterTrak is capable of measuring accurately on materials such as soft, fragile, abrasive and many other types of product where traditional contact methods have proved not to be effective. Even in industries where traditional contact methods have been used successfully the Proscan MasterTrak offers a more reliable measurement with less maintenance. Proscan MasterTrak is a real time thickness or width monitor, displaying absolute dimensions to the process line operator. In addition, the system logs every measurement, enabling detailed statistical reports to be produced. The Proscan MasterTrak has the option available for proportional feedback control for automatically regulating the process to maintain the correct dimensions.

The sensor naming convention is generally as follow:

First letter - S stands for Spectral (sometimes called chromatic or white light sensor)

First letter - L stands for Laser triangulation sensor

First number - i.e. 5, represents the distance from the target (stand off) in mm that the sensor needs to be at in order to take measurements 

Second number - i.e. 2, is the measureing range in mm of the sensor

Hence, an S5/03 sensor is a spectral type sensor with a 5mm stand off and a 300 micron measuring range.
