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.

Significant scientific and engineering enhancements in advanced materials, Pre-Process and In-Process production methods and in-site testing methods are driving the demand for displacement sensors that can handle extremely high temperatures up to 1832°F (1000°C). Contemporary producers of aircraft engine rotational alignment, plate glass, materials testing extensometry, continuous flow steel, now use standardized high temperature Capacitec sensor solutions for in-process applications to control the quality of their production on a real time basis. Qualification testing of disc brakes, jet engine dynamics and high speed shaft rotations also rely on Capacitec sensors. Advanced materials for automobiles, structural components, and aircraft are also tested for strength and durability with the use of Capacitec's line of extensometers and clip gauges.

ATLAS, POLARIS and ANTARIS laser displacement sensors work by the triangulation principle of measurement.
Single sensors measure displacement, depending on combination and placement you may measure thickness, width, height, length, straightness, flatness, profile or diameter.
Based on a Digital Signal Processor (DSP) the intelligent sensor controls the exposure of the CMOS and the output power of the laser source.
Due to this, LAP laser sensors measure extremely precise and fast, even if surface characteristics like color or reflectivity are changing.
Parameter like measurement speed or filters are handled directly in the sensor's DSP.
Digital workflow from CMOS to evaluation software eliminates the error sources of analog measurement. Still, ATLAS, POLARIS and ANTARIS sensors offer an analog output 4-20 mA.
ATLAS sensors can be connected by RS485, e.g. to further LAP sensors, to I/O modules, encoders ... .
Optional you may use interfaces to Ethernet UDP, Profibus DP or RS232.

Cable displacement sensors are based on an extremely simple operating principle, transforming the linear displacement of the cable into a rotary displacement by means of a drum connected to a return spring.
The sensor outputs a signal proportional to the cable displacement through a hybrid potentiometer or an encoder fixed to the drum shaft.
The signal is then an analogue signal (voltage or current) or a pulse signal.

AC operated Linear Variable Differential Transformers (LVDT’s) contain no electronics and are therefore the first choice when small size, hostile environments or low cost are required. AC LVDT’s when used in conjunction with Measurement Specialties Signal conditioners (see Instrumentation) offer the maximum amount of flexibility for outputs and scaling. Ranges from +/-0.005” to +/-10.000” are available.
The E Series of LVDTs is economical and satisfies numerous applications where LVDT performance and reliability are desired, but where budgets are limited. Linearity is 0.5% of full-range for all units except the E2000. The E series is particularly suitable for moderate operating temperatures. Its rugged construction will resist the shocks and vibrations encountered in most industrial applications. The E series is housed in magnetic stainless steel for protection against electromagnetic and electrostatic interference.

Microprocessor chips have found their way into a surprisingly high number of products that are around us every day in our home, car and office. This explosion in worldwide demand has forced semiconductor manufacturers to enhance quality and throughput in ways never before imagined. Capacitec's microinch level positioning sensing systems assist chip processing and handling equipment manufacturers to sense silicon wafers for exact positioning prior to deposition, etching and other processing where generating unwanted particles is preferred. This is accomplished without coming into contact or damaging their highly sensitive surfaces. Other industries where sensitive surfaces must be measured damage free are printing presses, photocopier rollers, computer hard disc drives and molten materials.

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

The Series 925 Linear Cable Reel Sensor can be used in any linear application up to 1200 inches. The system consists of a heavy-duty spring motor assembly attached to a precision-machined cable drum. As the cable is pulled off of the precision drum, the drum rotates a shaft connected to it. The shaft is precisely geared such that the full number of revolutions of the drum is equal to the appropriate number of revolutions required by the chosen sensor. There are three basic models. The Series 925 Linear Cable Reel Sensor can be used with our Series 1746 Resolver Input Card and a Series 2120 PLC Transducer Module.
