Inductance - Import export

With our infrared pyrometers you are able to finely control the exact heating of your production processes and guarantee point perfect temeperatures and repeatability of your process.

Our high frequency converters are providing frequencies of up to 2 MHz at up to 200 kW output. For lower frequencies down to 4 kHz we have our mid range frequency converter series MU.

Our Inductors are individually crafted for your exact production process. This ensures point perfect delivery and is maximing the energy efficiency of your heating process.

An alternative to conductive heat sealing is contact induction sealing, which is particularly suitable for sealing demanding container materials such as e.g. glass, metal or ceramic. An electromagnetic field is built up by a generator via an induction coil that is housed in the sealing head. The molecules of the aluminum foil are set in rotating vibrations, creating heat that is used for the sealing process. Our sealing machines PolySeal Vario PN and PolySeal Vario Twin as well as all fully automatic sealing systems can be equipped with induction technology.

Inductive proximity switches are contact-free sensors. They detect all conductive metals, regardless of whether they move or not. The achievable sensing range of the devices depends on the object material and its dimensions. The vibration-resistant sensors can be approached laterally or frontally. Inductive proximity switches are used for presence detection (e.g. goods carriers), positioning (e.g. dampers), counting (e.g. nuts /bolts), speed detection (e.g. for cog wheels), on conveyor systems (e.g. hose feedings) or distance measurements (e.g. press-in checking) of metallic objects.

The induction generator module is designed to supply up to 6 induction coils (inductors) with a power of up to 3 kW each. The device operates on the three-phase mains with a voltage of up to 400 V and a frequency of 50/60 Hz. The mains current is rectified and fed to the DC link, from which the inductors are individually supplied. The output power is controlled via the Kendrion controller of the modular industrial heating system. The setting range from 0% to 100% can be selected individually for each channel. By using state-of-the-art semiconductor switches, the output stages achieve high efficiencies, at working frequencies up to 25 kHz.

The controller is a fieldbus device for the control of up to 7 power modules from the modular heating System from Kendrion, which are directly connected via the module bus. In addition to system monitoring, the controller can also control or regulate the individual output channels of all power modules.

Inductive sensors detect metal objects contactless and wear-free. For this, they use a high-frequency electromagnetic AC field that interacts with the target. Their strengths are the enormous durability, reliability, high switching frequencies and a long service life. Through a unique coil concept the uprox® sensors offer the highest switching distance, factor 1 for all metals and, right from the start, the highest operational safety through simple and safe installation.

The inductive coupler of the NIC series is designed for contactless bidirectional transmission of power and data. The devices consist of two components, the primary part NICP and the secondary part NICS. The primary part supplies the secondary part with power via the air interface. In return the secondary part provides data to the connected sensors and actuators.

The inductive linear position sensors of the Ri series operate contactless and wear-free according to a new, revolutionary measuring principle: The angular position is not detected via a positioning magnet but via an oscillating RLC circuit. The sensors are thus completely immune to magnetic fields such as generated by large motors for example. The measuring range of the rugged angle sensors is 360°. As starting variants analog voltage or current outputs and switching outputs are available.

With the Therma friction thermocouple you can determine the surface temperature of the brakes while driving. Attaching the mounting adapter puts uniform pressure on the brake disc through the spring-loaded sensor by using a bayonet cap. That perfectly compensates movements caused by centrifugal force and vibrations as well as the volume decrease caused by disc wear while ensuring a valid measurement. The brake disc friction sensor measures the surface temperature of the brake disc. It imparts important insights about the temperature development. That enables an indication about the brake line, intake and temperature radiation. A brake disc that becomes too hot during a race massively loses its effectiveness and deceleration to the accustomed and optimal degree is no longer possible. If the temperature is too high, the brake pads start gassing on top of that.

Surface mount inductors are used for heating processes in the food industry, in packaging machines or in embossing processes in the graphics industry. The material thickness of the heated tools can be reduced due to the surface energy input. This increases the dynamics of the process and saves energy.

■ Configurable output signal (4...20 mA, 0...20 mA, 0...5 V, 0...10 V, ±5 V, ±10 V) ■ DIN rail mounting ■ Low residual noise ■ Built-in cable break detection with alarm-output

he greatest challenge in the use of inductive displacement transducers is the optimization of linearity. Usual linearity deviations are around 0.30 % of the measuring range of the sensors. Values that are significantly below this can hardly be realized. With the help of the LVDT digital controller from eddylab, to which either one or two sensors can be connected, the linearity deviation of inductive displacement transducers can be almost completely eliminated. KeyFeatures ■ Improves linearity up to 0.01%. ■ High resolution (16 bit) ■ High dynamic range ■ Digital output CAN, USB interface ■ Analog output ■ High noise immunity

Roller inductors are used in the production of synthetic fibres or in embossing processes in the graphics industry. Different roll diameters can be applied and one or more axial heating zones can be realised depending on the requirements. An essential advantage of the roller inductors is the contactless energy transfer to the rotating roller. ; Roller inductors from 60mm diameter; No slip rings required; Divided into independently controllable axial segments; Optimal temperature control & uniform heating; Emission-free heating

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.
