Specific Sensors

Inductive sensors from Micro-Epsilon are based on the eddy current principle and designed for non-contact measurement of displacement, distance, position, oscillation and vibrations. They are particularly suitable when high precision is required in harsh industrial environments (pressure, dirt, temperature). Inductive sensors from Micro-Epsilon offer extremely precise measurements where sub-micron accuracy is required.

The specific sensor configuration of the linear displacement sensors in the LDR series is characterized by a short, compact design with small diameter. The compact design and the small sensor diameter facilitate the installation of the measurement systems in locations where space is restricted.

Micro-Epsilon offers a comprehensive range of capacitive displacement sensors. These capacitive sensors are used for displacement, position and also for thickness measurements. Different sensor designs enable optimal integration into machines and systems. The capaNCDT sensors achieve best values in terms of linearity, temperature stability and resolution. While sub-micrometer precision is reached in industrial environments, even sub-nanometer accuracy can be achieved in clean environments.

The SGS (Spindle Growth System) 4701 displacement measuring system is developed for high speed milling machine applications. Due to high machining speeds and the heat generated, the linear thermal expansion of the precision machine tool spindle needs to be compensated for in order to keep the tool in a defined position at all times. The SGS sensor measures the expansion of the spindle caused by thermal and centrifugal force. The measurement takes places typically on the labyrinth-ring. As well as the linear expansion, the temperature of the sensor is detected and output.These measurement values are fed into the CNC machine tool as correction values, compensating for any positioning errors.
