For its eddyNCDT series of non-contact inductive displacement sensors Micro-Epsilon has introduced a new vacuum feedthrough. The new eddy/fB0/fB0/triax feedthrough allows the sensors to be used in closed chambers for vacuum operation, as well as providing a suitable conduit as a wall duct for placement of the sensor inside a vessel. A pluggable version is available for all common eddyNCDT sensors.
Non-contact, inductive displacement sensors from Micro-Epsilon work on the basis of the eddy current measurement principle. Unlike conventional inductive displacement sensors, eddyNCDT sensors measure on ferromagnetic and non-ferromagnetic materials and offer high accuracy, frequency response and temperature stability. The sensors are insensitive to oil, dirt, pressure and temperature. This makes them ideal for integration into machines and OEM system applications.
Powerful controllers
The powerful eddyNCDT 3060/3070 inductive measurement systems from Micro-Epsilon are ideal for fast and accurate displacement measurements. These systems are equipped with a compact controller, sensor and integrated cable. They are factory calibrated for either ferromagnetic or non-ferromagnetic materials, or both. The systems are suitable for measuring high precision displacement, distance, position, runout, elongation, thermal expansion and oil film thickness in harsh industrial environments. The system is designed to work with the sub-miniature range of eddyNCDT sensors, which offer measurement ranges from 0.4 mm to 8 mm and measure to sub-micron accuracy with a frequency response up to 20kHz.
The eddyNCDT 3060/3070 measuring systems are dust-proof and protected against short-term immersion in water (IP67). The sensors are designed for an ambient temperature of up to +180 °C and an ambient pressure of up to 700 bar. Active temperature compensation is provided for the sensor and controller. This ensures high temperature stability of the entire measurement system.
For a wide field of applications
Modern fieldbus connectivity is provided by the industrial grade M12 Ethernet interface. The compact die-cast aluminium design and fieldbus connectivity enable the encoder to be integrated into a wide range of production equipment, machinery and systems. An easy-to-use web interface simplifies setup and configuration.
The DT3061/3071 controllers offer advanced features such as five-point calibration, setting of switching and temperature outputs, and storage of multiple characteristics. When two or more systems are used in parallel, there is no need to synchronise them. A new frequency separation feature allows the systems to operate in parallel without affecting each other. Typical applications include the measurement of shaft movement (lateral and axial runout), lubrication gap (oil film thickness), thermal expansion and machine monitoring in high-speed automated production environments. The system is also ideal for test bench, R&D and laboratory applications due to the controller's ability to store multiple characteristics.
