LVDT sensor with free moveable plunger. The non-contact measurement is completely wear-free. LVDT sensors are primarly used for measurement of movement, displacement and position in vehicles and machines.
Modifying the standard eddyNCDT sensors is sometimes necessary particularly for small and large series. Therefore, we modify the measuring systems according to your specific requirements, e.g., changes to the cable, sensor material and design, and to the controller. In particular, sensors with integrated electronics in a miniature housing or special sensor designs are often requested by systems integrators.
Housing and mounting options for sensor and controller
Pressure-resistant sensors up to 2,000 bar
Sensors with integrated or external controller, miniature design
Various materials for coil, housing and circuit boards
Individual cable lengths, specific target calibrations
Customized inductive displacement sensors with Embedded Coil Technology
For particularly demanding OEM projects, we recommend the Embedded Coil Technology (ECT). Due to the miniature sensor design in inorganic material, almost all degrees of freedom for the outer shape are given. If required, the entire evaluation electronics can be integrated into the sensor. This allows ECT sensors to be adapted to special installation situations. ECT sensors are suitable for the harshest operating conditions and have proven successful, e.g., in the alignment of mirror segments on telescopes, semiconductor production in ultra-high vacuum and mill gap measurement of refiners in the paper industry.
Available options:
High long term stability
Reproducible temperature course
Extremly robust mechanics
Ideal for high temperatures up to 350°C
Inductive high-power sensor system (eddy current basis) Product Technology
Non-contact eddyNCDT 3300 eddy current displacement sensors are designed for use in factory automation, for machine monitoring, for quality control and quality assurance. More than 80 differentes sensors models are available.
The eddyNCDT 3300 controllers are equipped with high performance processors for signal processing and further processing. Three-point linearization enables almost fully automatic linearization, which provides high accuracies for any metallic target and installation environment. With a frequency response of up to 100kHz (-3dB), the eddyNCDT 3300 is suitable for high speed processes. The high resolution enables reliable detection of very small changes in displacement and distance in the sub-micrometer range.
Comprehensive sensor range
The eddyNCDT can be operated with almost every Micro-Epsilon sensor model. As well as standard sensors with conventional designs, miniature sensors can also be supplied that achieve high precision measurements of the smallest possible dimensions. Pressure-resistant versions, shielded housings, ceramic types and other special features characterize these sensors, which achieve highly accurate measurement results despite their small dimensions. The miniature sensors are primarily used in high pressure applications, for example, in combustion engines.
Smart
The eddyNCDT 3100 represents the new generation of eddy current displacement sensors. The configuration of the measurement system is effected via a web interface which can be easily operated. Additional sensor are required. Since all characteristics are stored within the sensor, all eddy current displacement sensors of the series 3100 can be easily exchanged without requiring an additional calibration.
Performance
The eddy current displacement measurement system uses a patented temperature compensation method to provide first-class stability even in the case of fluctuating temperature. Due to the high resolution and linearity demanding measurement tasks can also be fulfilled. With a cut-off frequency of 25kHz (-3dB) the eddyNCDT 3100 can also be applied for fast measurements.
Universal
Both the controller and the sensors can be applied in harsh environments. Switching between ferromagnetic and non-ferromagnetic measurement objects can also be effected easily. For the measurement with different channels up to 10 controllers can be synchronized (eddyNCDT 3100-SM).
