As with the other color sensors of the CROMLAVIEW® family the CR500 processes colors perceptually (i.e. according to human color perception) and assesses color distances with the precision of the human eye. The CR500 can be parameterized by means of RS232 or USB interfaces. The free software CR-Tool – CR500 facilitates the parameterization of the color sensor and the visualization of color values. A distance monitor supports the adjustment of the fiber head. Besides that, the color sensor can also be operated using the buttons. Therefore the distance monitoring can be performed by means of 12 LEDs. As all the other CROMLAVIEW® color sensors the CR500 is equipped with CROMLASTAB®-technology, which protects from temperature- and aging drifts and ensures with this method a reliable operation over the whole lifetime cycle. The sensor contains a built-in white light source clocked with a frequency of up to 2 kHz. Sampling takes place in both, the light and the dark phase. Additive ambient light cannot change the difference between the light and dark phase, so that the sensor is independent from ambient light.
Operating Principle:
Distance compensated measurementFeatures:
The brand new CROMLAVIEW® CR500 features a new patented compensation algorithm for variable working distances. With this method – called CROMLADIST® – the sensor provides precise and reliable recognition results, even if the working distance changes within the process. In addition there is the well-known CROMLASTAB® function for drift compensation, which grants long term interruption-free operation without any maintenance.
The CROMLAVIEW® CR500 is equipped with a special optical fiber for easy adaption to application requirements. The parameterization of the sensor can be done by pushbuttons or by using the comfortable supplied PC software CRTool-CR500.
