PreciCura family
The result of 25 years experience in laser sensor development, the PreciCura is a robust, rugged and versatile laser triangulation sensor for dimensional measurements. The non contact sensor is ideal for most measurement applications including difficult to measure surfaces such as soft, delicate and hot materials as well as discrete parts and fast moving objects. The combination of LIMAB’s application know-how and constant development of sensors and solutions has created a family of distance measuring sensors with unmatched performance and reliability.
Smart sensor
The PreciCura is an intelligent sensor that adapts exposure time automatically to optimise the measuring performance irrespective of the type of material that is being measured. This means that accurate and repeatable measurements are always possible even on surfaces that are of different colours or have large changes in reflectivity.
Simple integration and ease of use
The PreciCura is powered by a single 24VDC supply. Calibrated measurements are available straight from the gauge using the standard analogue, serial or CAN-Bus interface that is provided. This makes interfacing to existing PLC’s or other computer system very straight forward.
Thickness measuring mode
Two PreciCura sensors can be connected in thickness mode. This enables the real time thickness or width of fast moving materials directly from the sensor. The internal processor handles the sampling synchronisation and calculated the actual width or thickness. Thickness values are available on the Serial or CAN-Bus interface.
Measuring Principle
The PreciCura uses the principle of laser based optical triangulation. A laser spot is projected on to the surface of the material being measured. The laser spot is diffusely reflected by the surface, this light is focused on to a CCD detector by a high quality lens system. The position of the light energy on the CCD array varies according to how far the target is from the sensor. The CCD array uses 2000 pixels and these are subdivided by a factor of 16 to provide a very high resolution of 32,000 over the measuring range of the sensor. The processor convert the pixel position to a mm position using a unique calibration look up table stored within the sensor.
