The confocal-chromatic measurement system, confocalDT, consists of a controller with a LED-light source and a sensor. Both, the sensor and the controller are connected via optical fiber up to 50 m. The distance of the focal point varies due to the chromatic aberration of the sensor optic. A certain distance is assigned to each wavelength in the controller. The reflected light from the target surface is passed to the receiver optics, where the spectral intensity dispersion is evaluated. This unique measuring principle enables displacements and distances to be measured with the highest precision. Both diffuse and specular surfaces can be measured. With transparent materials a one sided thickness measurement, or gaps between multiple transparent layers, can be accomplished along with the distance measurement with just one sensor.
- Extreme high resolution
- Target independent measurement
- Tiny, constant measuring spot
- No shadowing
- One-sided thickness measurement of transparent materials
Sensor solutions for the reliable inspection of wind turbines
Due to safety and cost reasons, wind turbines require 24/7 monitoring. Lightning, defective rotor blades or tower movements due to localized storms can have serious consequences until the wind turbine finally collapses. Precision sensor technology from Micro-Epsilon is already used during production as well as in the real-time monitoring of active plants. The sensors enable the plant operator to intervene early during production or to switch off the running wind turbine early enough to avoid danger or damage. Targeted monitoring using modern sensor technology reduces the costs of maintenance and servicing.
How to Reach Unrivaled Precision in Distance and Thickness Measurements with Confocal Sensors
Sensors that measure the distance to an object have many application areas in the manufacturing industry and in quality control. The requirements for the measurement system differ substantially depending on the respective application. The distance to be measured, the speed, the accuracy required and the type and surface of the object are just a few of the numerous factors that determine the choice of sensor. Sensors based on an optical measurement principle have the advantage of being neither subject to effects of electromagnetic interference fields, nor to the effects of wear. In addition, optical measurement principles enable very high resolution, accuracy and repeatability using a true non-contact technology.
Learn how capacitive sensors open up new perspectives
Conventional capacitive sensors are known from simple tasks e.g. as proximity sensor or for fill level measurements. With corresponding design and evaluation electronics, these sensors can also be used for high precision displacement and position measurements, achieving resolutions well below one nanometer. Capacitive displacement sensors are typically used in applications where fast displacement changes have to be acquired, where no forces can be exerted on the measurement object, where highly sensitive surfaces do not allow any contact, or where a long service life of the sensor is required. Capacitive displacement sensors from Micro-Epsilon have proven themselves in various industries and measurement tasks.
A Comparison of Blue and Red Laser Triangulation Sensors
Although red laser triangulation displacement sensors have been in use for more than 20 years, blue laser versions are also now available. Before selecting which colour to use, it is important to understand which type performs best on which target material.
Non-contact temperature measurement of plastics
In plastics processing where thermal processes play a particularly important role, temperature is the crucial measurement parameter. Only precise temperature control ensures high, consistent product quality. Micro-Epsilon provides suitable measurement technology from a single source for almost any material or polymer.
Thickness Measurement with Laser Displacement Sensors
Laser displacement sensors are often used for measuring distance, movement and dimensions. If the measured values from two sensors are evaluated together, the thickness of an object can be determined from this. However, in order to achieve a precise statement of the target thickness from the combined signals of two sensors, there are a number of factors that need to be taken into account.
