Specification

The POLARIS series sensors have proven successful in hundreds of difficult, high tolerance applications due to their extreme precision and rugged reliability. They provide non-contact measurement of dimensions such as distance, thickness, width, height, and flatness, without the need to stop the material for measurement. Thanks to their high-resolution CCD line array and the integrated Digital Signal Processor (DSP), they provide accurate measurement results for online process monitoring and control. Through tighter process control, return on investment (ROI) can be achieved within a short period of time.

 

1. Highest resolution (down to 0.2 μm/7.9 μin)

6. Programmable filter functions
7. Flexible interfacing options

 

POLARIS sensors are equipped with:

1. RS485 serial interface
2. 4 - 20 mA analog output
3. 2 discrete outputs (optional)

 

Additional interface modules are available for:

1. RS232 ASCII
2. Ethernet UDP
3. Profibus DP

Features/Benefits

 

 

The POLARIS series sensors provide precise results on virtually all materials at any production speed. They automatically adapt to changing colors and surfaces. Even measurements on shiny aluminum, non-vulcanized black rubber, and on soft or sticky materials are possible.

The POLARIS sensors measure distance, thickness, width, height, straightness, flatness, profiles and a whole lot more. They simplify measurement by combining easy operator setup and flexible interface modules. Multisensor applications, which in the past would have required external processors and programming, are now done easily in the POLARIS using the on-board DSP and multi-drop RS 485 capability, providing easy communication and math capabilities. The POLARIS also provides unrivaled real-time process monitoring. Immediate and precise feedback of process parameters allows corrections to be made quickly with minimal downtime. Simple control tasks like loop control and accept/reject are no problem using the programmable discrete outputs.

  Brackets                                     Air Purge Housing Unit

 

1. These additional housings protects POLARIS sensors from dust, dirt and temperature influence. Airflow should be produced by a fan, compressed air is not first choice. Depending on ambient conditions, the airflow can be heated to prevent fogging and icing or cooled to increase the lifespan of the sensor, specially the laser.
2. Brackets for POLARIS sensors are used for easy fine positionning and changing of sensors.
