The new confocalDT IFC2461 extends the confocal chromatic controller range. It stands out due to higher measuring rates up to 25kHz. Particularly with dark targets or when measuring the thickness of transparent targets, the advantages of the enhanced, optical components become clear.
Enhanced, optical components, more powerful measurement characteristics, no external light source – in short, these are the three key attributes that accurately describe the new confocalDT IFC2461 confocal chromatic controller. The range of controllers for confocal sensors has been extended by a further model. Not only does the confocalDT IFC2461 provide higher measuring rates up to 25kHz for faster measurements and control of dynamic processes, but also delivers stable measurement results. Compared with a Xenon light source, the integrated light source is more durable, resulting in reduced maintenance and purchase costs. An active exposure time regulation feature allows different surface types to be measured.
Two different controller versions are available: the standard version and a multi-peak version. The latter provides six peaks, enabling one-sided thickness measurement of up to five layers. The IFC2461 is primarily used in the production of glass, bottles and displays, or when high speed inline processes are involved.
The confocal chromatic sensors are used for distance measurement, as well as for measuring the thickness of transparent materials. The high end controllers achieve measuring rates of 10 kHz (IFC2451), 25 kHz (IFC2461) or 70 kHz using an external Xenon light source (IFC2471) and offer EtherCAT, Ethernet, RS422 and Analogue Out. Optical signals are transferred between sensor and controller via an optical fibre.

Equipped with a scanCONTROL laser scanner from Micro-Epsilon, a special vehicle inspects the inside of a pipeline for deformations and cracks. This mobile device is used in harsh environmental conditions and high ambient temperatures, e.g. in the middle of the desert and is ideally suited to automatic inspection and recording of measured data.
To meet safety regulations, the inspection of the internal parts of pipelines is mandatory, as any deformations can lead to cracks, which could result in complete pipe failure or, in the worst case, to personal injury. The critical factor is the weld seam. DEKRA developed a fully automatic vehicle that solves this task by using a combination of visual inspection and geometrical measurements performed by a scanCONTROL laser scanner from Micro-Epsilon.
To make the vehicle suitable for different types of pipeline in all regions of the world, it is protected against sand, dust and ambient temperatures up to 100 °C. In combination with the fifth wheel on the top of the vehicle pressed against the top of the pipeline, the ROV can travel up a high gradient of around +/- 45°. All data can be output for further use or, if desired, trigger an alarm as soon as an anomaly is found in the geometry (roundness, defects, welds, etc.).

The eddyNCDT 3005 from Micro-Epsilon is a new, powerful eddy current measurement system for fast, high precision displacement measurements. Due to its pressure-resistant, thermally stable and compact design, the eddyNCDT 3005 is ideal for machine integration.
Non-contact eddy current sensors from Micro-Epsilon are designed for extremely high precision measurement of displacement, distance, position, oscillation and vibration, etc. to micrometer accuracies. Pressure, dirt, oil or high temperatures have almost no influence on measurement precision. This eddy current measurement system is particularly suitable for harsh industrial environments. As the sensor and compact controller of the eddyNCDT 3005 are temperature-compensated, outstandingly high measurement accuracies can be achieved even in high or fluctuating temperatures, e.g. in automotive production. The sensors are designed for ambient temperatures up to max. +125°C but can also be custom engineered for temperatures from -30°C to +180°C. Controller, cable and sensor are pressure-resistant up to 10 bar. Compact, robust sensor designs and high measurement accuracy, combined with a particularly favourable price/performance ratio, make these sensors suitable for high volume applications and for integration into plant, equipment and machinery.

Micro-Epsilon presents the new, confocal chromatic sensors for the confocalDT measurement system. The IFS2406 series stands out due to its compact design and high precision. As well as for distance measurements at submicrometer accuracies, the sensor is suitable for the one-sided thickness measurement of different materials.
The confocal chromatic sensors from Micro-Epsilon are non-contact, maintenance-free, provide long-term stability and so are ideal for high precision measurement applications. The confocalDT from Micro-Epsilon includes the fastest controller currently available in the world and achieves measurement rates of 10kHz using an LED light source and 70kHz using a Xenon light source. It provides high precision measurement results in displacement and distance measurement tasks, as well as thickness measurement of transparent objects. A wide range of sensors and various interface options such as Ethernet, EtherCAT, RS422 and analogue output open versatile fields of application.
The IFS2406 sensors are specially designed for vacuum applications. These models stand out due to their compact size, submicrometer accuracy and a small measurement spot size. Due to its axial and radial measuring directions, the sensor models are extremely versatile in terms of their use. Due to their passive design they can even be used in Ex areas. The measurement channel is parameterised via a comfortable web interface which makes it unnecessary to install a separate measurement software.
As well as distance measurements on reflecting or transparent surfaces, these sensors can also be applied in one-sided thickness measurement of transparent film, plates or layers. Typical fields of application includes displays and glass production, medical engineering and research and development.

The new handheld thermometers of the thermoMETER P20 series from Micro-Epsilon cover a broad temperature range from 0 to 2000 °C. From four models, the user selects the appropriate pyrometer for the respective temperature range and field of application out of four models.
The thermoMETER P20 series stands out due to its high optical resolution and numerous detection wavelengths. P20 reliably detects object temperatures at a maximum distance of 12m. Integral laser aiming or telescopic sight enable exact sighting of targets. A data logger stores up to 2000 measured values. Data output is via a USB interface.
The main fields of application for the portable pyrometers of the thermoMETER P20 series include temperature measurement in the primary and secondary steel processing e.g. in forging processes or in foundries.
December 10, 2014Capacitative movement sensors
The multi-channel measurement system for capacitive displacement sensors based on the modularity principle, capaNCDT 6200; has now been extended by the new controller DT6230. Compared to its “little brother”, the DT6230 does not only offer an Ethernet but also an EtherCAT interface as well as an integrated synchronisation. Thereby, the whole system offers more flexibility.
In combination with the demodulators DL6220 and DL6230, the new mid-range class is more flexible than any other system: The single components – controller, demodulator, sensor – are freely interchangeable and allow customer-specific systems to be provided from stock. With a unique modular design, sensor systems that have already been purchased can be enlarged easily.
The capaNCDT 6200 series is a unique modular multi-channel measurement system for capacitive displacement sensor and particularly stands out due to its excellent price/performance ratio. The measurement system consists of one controller and the respective demodulator for the sensor. The controller can be extended to 4 channels. All capacitive displacement sensors from Micro-Epsilon can be used with the capaNCDT 6200 controlle , which can measure thickness, tilt angle and vibrations in the sub-micrometre and nanometre range.

The new eddy current-based sensor system measures the rotational speed of turbochargers in bench and field tests. turboSPEED DZ140 is optimised for thin turbine blades made from aluminium or titanium. The system is thermally stable and very well protected from external interference.
The turboSPEED DZ140 is the fourth generation of eddy current-based revolution counters for turbochargers. The sensor system is suitable for speed measurements of 200 to 400,000 rpm. The sensor is just three millimetres in diameter, yet it provides the highest immunity to interference in harsh test conditions. The integrated temperature measurement feature records – among other data – the actual ambient temperature near to the sensor. The turboSPEED DZ140 provides much higher immunity to interference than other eddy current-based revolution counters. The DZ 140 eddy-current measuring system is resistant to oil and dirt. The maximum operating temperature of the miniature sensor is 285°C, which is a key advantage compared to optical speed measuring systems, as this helps to achieve high precision measurements on a continuous basis. The well engineered design also enables easy sensor replacement without further adjustments.

In order to minimise positioning errors in machine tools, the eddy current sensor SGS 4701 measures the thermal extension of high-frequency spindles.
The spindle is at the heart of a machine tool and so plays a decisive role in the dimensional accuracy and surface quality of the respective workpiece. High speeds and the heat generated result in the axial extension of the workpiece spindle and to the resultant positioning error during finishing of the workpiece. The new eddyNCDT SGS 4701 miniature eddy current sensor measures the thermal and centrifugal force extension of high-frequency spindles by measuring on the labyrinth-ring. The measured values are fed into the CNC machine tool as correction values and compensate for any positioning errors. The miniature sensor models have dimensions of 4.5 x 10 x 12 mm³ or 4 x 4 x 10 mm³ and can be integrated with the controller into the machine tool spindle. For ease of handling and in order to achieve maximum accuracy, the eddyNCDT SGS 4701 is factory calibrated for ferromagnetic and non-ferromagnetic materials used by the customer. For temperature compensation of the eddyNCDT SGS 4701, the temperature of the sensor is measured via the resistance of the eddy current coil. This signal is also available to the customer, which can eliminate the need for any additional temperature sensing technology. Due to its interchangeability with the previous model, the new mini-sensor technology can be easily upgraded at any time. This sensor is now available as a standard catalogue product and suited for OEM modifications as well.
