Capacitive sensors - operating principle and applications
Capacitive sensors are used
whenever high precision measurement results are required. They measure
vibration, oscillation, deflection, expansion, displacement, deflection,
deformation, thickness, etc.
Capacitive sensors from
Micro-Epsilon also stand out in industrial measuring tasks. Based on the
intelligent triax technology, the measuring systems are insensitive to
interference fields and extremely stable in fluctuating ambient
temperatures. Suitable for high temperature ranges from -270 °C to over 200 °C,
these sensors are ideal for harsh environmental conditions.
How to use color sensors for quality improvements and innovative automation tasks
In many industries, color implies quality. Particularly with consumer goods that arrive at the final customer, the exact color shade affects the value and identity of the product and the brand. Therefore, it is crucial to match the correct color shade in the production process and to produce it homogeneously throughout numerous batches. Color not only leaves behind a quality impression but can also be used as indirect quantity to control the process. For example, color sensors are used to monitor the presence of adhesive beading, to sort parts or to determine active ingredients. Color sensors are in most cases the more cost-effective solution as they provide more precision than conventional switching sensors do.

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.
