The confocal chromatic measurement system, optoNCDT 2401, consists of a controller and a sensor. A fiber optical cable, which can be of almost any length, connects the two components. This system has no moving components and is therefore wear free. It can also be used in ATEX / EX environments. The system consists of a LED based controller a fiber optical cable and one of the sensor heads of the series 2400/2401 or the world first miniature sensors series 2402. This unique measuring principle enables displacements and distances to be measured with high precision and extreme
spatial resolution. Both diffuse and specular surfaces can be measured. With
transparentmaterials a one-sided thickness measurement can be accomplished along with the distancemeasurement. Since the emitter and receiver are arranged in one axis, shadowing is avoided. In contrast to conventional triangulation sensors the optoNCDT 2401 system is able to measure in narrow apertures, small gaps and cavities. The series optoNCDT 2402 is also with radial beam deflection for bore hole inspection available.

The program of ODS Black-line laser sensors are a series of sensors based on optical triangulation, with different measuring ranges and resolutions, used in various environments, from the very hot and harsh applications in the heavy industry to the delicate applications in laboratories. Potential applications are innumerable. From food and medical industry over wood-, rubber- and offshore industry to milling marble, stone and cast iron – everywhere a non-contact precision measurement is valued. Seven different measuring ranges are available, the smallest covers 16 to 25 mm and the largest 400 to 1100 mm. Furthermore all ODS Black-line sensors are available with measuring frequencies of 2 kHz and 5 kHz. Higher measuring frequencies give shorter distance between the individual measuring points on a moving target, and increase the possibility for averaging over a sufficient number of measuring points to obtain a required high resolution. Apart from the standard models, all ODS Black-line sensors are supplied with a Select functionality, allowing the sensor to be programmed to calculate a user defined running average. Software with every sensor provides easy setting of the Select parameters. For more detailed information please study the PDF/datasheet on our website www.sensor.dk

POSIC presents a new type of inductive position sensor for the measurement of gears, disks and linear bands. The IS1101 sensor consists of a differential microcoil transformer that is integrated on a silicon chip together with the associated electronics, leading to an extremely robust and very compact sensor.
The differential inductive sensor has a high immunity against magnetic and electromagnetic perturbations, does not need a bias-magnet and works with ferromagnetic (iron, nickel) as well as with electrically conducting (aluminum, copper, brass) gears and discs. These features make the microcoil sensor ideally suited for applications where magnetic sensors fail or show reliability problems.
Typical applications are in the motion control domain with magnetic actuators like brushed and brushless motors, voice coil actuators etc. Markets served include industrial, automotive, robotics, medical, instrumentation and office equipment.
The IS1101 sensor comes in the form of a 9 x 6.8 mm PCB with alignment/fixation holes, ready for assembly in e.g. an electric motor or an industrial machine.
The IS1101 sensor as well as the corresponding evaluation kit are available from stock.

Wilcoxon Research adds a displacement sensor to its popular PC420 Series of 4-20 mA vibration sensors. The PC420D is the first IEPE displacement transducer and 4-20 mA vibration transmitter packaged as a single sensor. The PC420D sensor outputs a 4-20 mA signal based on the displacement level of the machine vibration. The 4-20 mA output is determined by first measuring the peak to peak vibration, then converting that level to a 4-20 mA signal. Because balance components tend to dominate the vibration spectrum when viewed in displacement units, the PC420D sensor is able to track the balance component of machines, one of the most sought after parameters. Integrating this signal into an existing PLC, DCS or SCADA system simplifies real time health monitoring because vibration, formerly considered too complex, can now be trended in easily understood units of mils or millimeters of displacement. Measuring displacement can unmask hidden problems and provide data in easy to understand measurement units. Instead of converting to displacement after the measurement is taken, a common practice in diagnostic vibration monitoring systems which can introduce errors known as “ski slopes”, the PC420D sensor integrates at the measurement point for the cleanest vibration data. The PC420D is ideal for condition based monitoring and predictive maintenance of motors in the speed (frequency) range of 300 rpm to 60,000 rpm (5 Hz to 1,000 Hz). The PC420D can be widely used to monitor balance of plant instrumentation such as pump motors, blowers, fan motors, compressor motors, and a wide variety of machine tool drive motors to significantly reduce failure rates in the field.
