How measurement sensors improve the performance of tooling machines
Faster, more precise, higher productivity - these are the key requirements when developing new machine tools. In many cases, improvements can only be achieved using sophisticated sensor technologies. Micro-Epsilon demonstrates this with a wide range of applications that are ideally suited to the machine tool industry.

A Comparison of Blue and Red Laser Triangulation Sensors
Red laser sensors have been in use for over 20 years now and are known to perform well and have improved in recent years to provide good measurement stability on a wide range of dynamically changing surfaces, including low reflectivity and matt surfaces, as well as on fast-moving objects. However, on certain materials, red laser sensors perform less well. So when is it best to use a blue laser triangulation sensor over a red one? To answer this, a number of factors need to be considered. 

Learn Why Eddy-Current Sensors Are Now Replacing Inductive Sensors and Switches
Both eddy-current sensors as well as inductive switches and displacement sensors have been used for many years, each having their respective advantages when it comes to measuring position and displacement of objects in harsh environments. However, recent advances in eddy-current sensor design, integration and packaging, as well as overall cost reduction, have made these sensors a much more attractive option. This is especially true where high linearity, high-speed measurements and high resolution are critical requirements.

How to Reach Unrivaled Precision in Distance and Thickness Measurements with Confocal Sensors
Confocal chromatic measuring systems are increasingly used for fast distance and thickness measurements. Different sensor and controller models open versatile fields of application, e.g. in the semiconductor industry, glass industry, medical engineering and plastics production.  The unique optical confocalDT measurement system from Micro-Epsilon is based on the optical measuring principle, which specifically takes advantage of the so-called chromatic aberration of light. This refers to the different refraction of light in relation to its wavelengths. It measures distances by means of wavelength (spectrometry).

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.

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.
