Eddy current - Import export

Eddy Current separation system consists of a conveyor belt and a rotor with a magnetic circuit built in 14 or 24 poles; to adapt to the grain-size distribution of the product. All within a steel case and covered by a counter drum . Being separates, the drum and the rotor inductor, allows operation at different frequencies. When the rotor turns at high speed it generates an electric current in the conductive metals (nonferrous), this inductive voltage produces a magnetic field opposite to the rotor, causing the non-ferrous metals being repelled. The rejected metal falls into the hopper by gravity, being separated from the other material. Eddy Current separators are indicated for the separation of non-ferrous metals: aluminum, brass, copper, etc., from inert materials. Used by recyclers in various sectors, production of semimanufactured and other processes. Separation of nonferrous metals in: car crushers, foundry slag, foundry sand, debris in domestic and industrial recycling companies

With an extended measuring range up to 45mm, the new eddy current sensor series completes the product portfolio of eddylab GmbH and at the same time combines all advantages of a non-contact eddy current measuring principle: With wear-free distance and displacement measurement, eddy current sensors are characterized by highest precision and dynamics. The new T14/T20/T40 series can withstand extreme temperatures in a range of -40...+150 °C without any problems and is insensitive to external influences such as dirt and dust. The new sensors with measuring ranges between 14 mm and 45 mm are also extremely compact and robust. This makes them ideal for use in difficult industrial environments or vibration measurements with larger amplitudes. Together with the TX electronics from eddylab GmbH and the eddy current software eddyMOTION, measurement data can be analyzed, visualized, and documented.

eddyMOTION is a Windows-based analysis and configuration tool for eddy current probes. In combination with the TX electronics from eddylab GmbH, the software tool combines several performance features: The functional areas oscilloscope, FFT analysis, data logger and waterfall diagram, enables the visualization and documentation of mechanical movements. eddyMOTION also suites the on-site linearization of eddy current sensors in a traceable manner, without external assistance. In addition to the TX electronics and an eddylab eddy current sensor, a reference probe is required for this purpose: Together with the eddy current sensor, this probe measures the distance to the same material, with the reference probe serving to check the sensor.

The eddy current sensor series IC with integrated electronics guarantees highly accurate measurements thanks to linearized characteristic curve. Accuracy has been improved by up to a factor of 20 compared to previous models. The teach-in function allows the measuring range of the eddy current sensor to be optimally adapted to the respective application. Installation tolerances or material properties of the measured object can be compensated directly. Setting individual measuring range limits offers the user the greatest possible flexibility and simplifies sensor integration. As the complete analysis electronics are built into the sensor, installation and mounting are also extremely uncomplicated.

Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, providing high continuous power ratings (max. 140 kW). The WB dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale (± 2% for WB 2.7), depending on size and system configuration. Additional options include: high-speed version, speed pickup, mechanical rotor blocking device, OEM version IS and vertical mounting.

The CM-Sensors are specially designed for demanding applications: They withstand high pressures up to 100 bars (and more) at temperatures up to 190 °C. At conventional sensors with a similar size the probe head must be kept free from surrounding conductive objects, in order to avoid pre-attenuation of the measuring system. In contrast, the socket for the CM-sensor does not require additional notches or holes.This feature arises from the utilization of zirconium oxide as housing material and ferritic components with a focusing effect. The CM-sensor is typically applied to monitor the orbit of a turbocharger’s shaft.Its ball bearings have a squeeze film damper to reduce the rotor vibration. In order to optimize the entire system the CM-sensors detect the exact position of the turbine- and compressor wheel under real operating conditions.

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.

The system RTP 8301.EO operates according to a combination principle consisting of a thru-beam sensor, an eddy current sensor and a measuring roller. The eddy current sensor and the thru-beam sensor are applied on an innovative measuring clamp. Since the sensor measures the distance from the clamp to the roller, the lower side of the material is detected. As the sensor performance is specially aligned with the measuring task a huge measuring gap is possible while offering highest precision. The thru-beam sensor detects the upper side of the material. The thickness of the target is the difference between the two signals. The measuring clamp is equipped with a pneumatically cleaning mechanism and therefore ideal for the application in harsh environment. The profilometer corresponds to the TIP 8301 regarding its functionality. However, it has a different operators´ frontend and evaluation functions.

This unique sensor concept enables one-sided thickness measurement of electrically non-conductive materials on metallic objects. Its field of application is the thickness measurement of plastic film or of plastic coating on metal plates. The eddy current sensor penetrates the plastic layer and measures the distance to a metallic material underneath it, e.g. a metal plate. The capacitive sensor synchronously detects the distance to the plastic material. The thickness is determined based on the difference of both sensor signals.
