Current sensors - Import export

CSN® Current Sensors are used for current measurement in control and protection systems in power transmission links (AC and DC applications). The CSN® type Current Sensors are based on highaccuracy resistive sensors (shunt) respectively iron free cores (CSN® AirCoil). There are selfsupporting structures available where the CSN® Current Sensor is mounted on top of a composite insulator, as well as variants in which the CSN® Current Sensor will be mounted hanging in the busbar. Schniewindt has implemented CSN® Current Sensors for nominal currents of up to 5 kADC at system voltages of 800 kVDC, which have been successfully typetested. Also for the precise measurement of small currents (1 to 10 A), such as transient currents in capacitor banks, Schniewindt offers appropriate solutions. All of our CSN® Current Sensors are individually designed according to customer requirements.

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.

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.

■ Measuring on turbo vanes and shafts ■ TTL output for speed measurement ■ Analogue monitor output for gap control ■ High resolution ■ High dynamics ■ Low current consumption ■ High noise immunity

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.

High-quality eddy current probes: Beside robustness, high dynamics and high resolution the TX-Series also stands out with a wide temperature range from -60 °C up to 180 °C. ■ High precision measurement ■ High resolution (submicrometer) ■ High dynamics (124 kSa/s) ■ Minimal temperature coefficient ■ High noise immunity ■ Custom-made probes

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.

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.

With an additional current transformer, the production data of the inverter can be recorded and visualized in the VARTA monitoring portal. As a result, you do not need a Solar-Log data logger to integrate the inverters.

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.

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.

The FTS 8101.EC O-frame is based on the combisensor principle equipped with non-contact capacitive sensors. The distance between sensor and film is measured with the capacitive sensor. The eddy-current sensors ensures the thickness signal by a reference measurement to a second target. The system can be integrated in the flat layer section.

In its sensor housing, the combiSENSOR combines two displacement sensors. 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.

The eddyNCDT 3001 comes with integrated electronics, offering an outstanding price/performance ratio and easy operation.

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.

The FTS 8102.EC C-frame is based on the combisensor principle equipped with non-contact capacitive sensors. The distance between sensor and film is measured with the capacitive sensor. The eddy-current sensors ensures the thickness signal by a reference measurement to a second target. The system is designed as a C-frame and can be used as a traversing unit by using the linear axis.

The BTS 8101.EO O-frame is based on the combisensor principle. The system is equipped with a non-contact capacitive sensors and a Thrubeam sensor which are integrated in a traversing frame. The eddy current sensor measures the reference distance to the measurement roll‘s metal surface. The distance from the film surface is measured by the Thrubeam sensor. Together with the reference signal the film thickness is calculated. This combisensor principle allows extreme precise measurements.

The rectifier with built-in current sensor for fast turn-off is designed for the operation of electromagnetic devices. It ensures fast turn-on and turn-off. The rectifier with bridge circuit comprises a thyristor and timer. During overexcitation, the rectifier delivers bridge rectified output voltage before changing over to half-wave rectification. On the DC side, the output voltage is enabled by the built-in current sensor which measures the AC current of the connected motor. If the motor is stopped, the rectifier turns off on the DC side as soon as the current falls below the turn-off threshold. The turn-off voltage generated by the inductive load is limited. The rectifier is suitable for connection in parallel with AC motors. The current sensor must be wired into the motor current path in such a way that the current flow created when the motor operates in generator mode will not pass through the sensor. This is crucial to avoid delayed or impaired DC side switching.
