PROFILE and GAP MEASUREMENT for all industries
OPTARIS M is a family of laser light section sensors. They measure the height profile of an object by projecting a laser line on its surface which is captured by a camera element from a specific angle. All geometrical changes of the surface, like edges, angles, gaps, grooves or curvatures generate deformations of the straight line from the cameras angle of view. The real coordinates can be calculated by the size of the deviation. For objects moving through the measuring field this process produces a complete 3D height profile.

Pearson Electronics is pleased to introduce two new Wide-Band Hinged Clamp-on Current Monitors with fast rise times. The models 8585C and 8590C feature a 2.0 and 2.5 nanosecond rise times, a ½ inch and 1 inch aperture, and are hinged for easy operation. The new design incorporates Pearson’s wide band frequency response in a demountable configuration for use on fixed conductors.
Both models have a 1.0 V/A sensitivity, a 3dB bandwidth from approximately 1.0 KHz to 200 MHz, and a 5 Ampere rms current rating. Accuracy of 1%, or less, is obtainable across the mid-band. Pulse currents up to 500 Amperes can be viewed. Other new hinged clamp-on designs feature a range of transfer impedance from 0.01 V/A to 1.0 V/A allowing for accurate measurements at lower frequencies. A typical model has a 3 dB bandwidth of 25Hz to 15 MHz, with some models as low as 5 Hz. All of the new hinged clamp-ons are featured in our Clamp-on Current Monitor section along with existing custom and stock designs.

Extended Dynamic Range CEMs
Channel electron multipliers (CEMs) are detectors, which respond to charged particles, hard and soft X-rays, and ultraviolet radiation. The extended dynamic range of CEMs are available with circular openings from 5mm to 25mm and rectangular openings from 2mm x10mm to 10mm x 10mm.
A CEM has a high surface resistance. When a potential is applied between the input and output end of the CEM, the resistive surface forms a continuous dynode. A dynode has the property of emitting secondary electrons when primary particles impinge upon it (Fig. 2). This process is called secondary electron emission. Through this process, a CEM is capable of detecting a particle or photon that has entered its funnel-shaped input aperture. These primary particles generate secondary electrons that are accelerated down the channel by a positive bias. Upon striking the interior surface of the channel walls, these electrons then generate further secondary electrons. The resulting avalanche process produces an easily detectable output pulse of charge containing up to 10e8 electrons with a duration (FWHM) of about 8 nanoseconds.If the electron cloud is collected with an anode, a single pulse is produced that appears on the oscilloscope as shown in Fig. 3. For an input of one primary particle a CEM thus produces an electron cloud of about 100 million electrons. The output pulses can be detected easily by using a discriminator, a preamplifier and a counter or as an input current in the analog mode.

LAP measurement systems – non contact displacement 
measurement.
LAP laser sensors measure dimensions without touching the object’s surface. Production processes can be monitored continuously, ensuring quality and reducing rejects.
LAP measurement systems are flexible and easy to integrate, with very capable software.
Having no contact with the object to be measured lets the user work with soft, sticky, hot or other sensitive surfaces. There will be no wear and tear at the sensor. Keeping the sensors’ windows clean can be done by air purging.
All systems incorporate laser triangulation sensors. Measurements of displacement, thickness, width and height, etc can be made. Depending on the type of system purchased, measurement ranges from 0.2mm to 4000mm are possible and accuracies down to ±0.1 micron can be achieved.
Based on a Digital Signal Processor (DSP) the intelligent sensor controls the exposure of the CCD and the output power of the laser source. Because of this, LAP laser sensors measure extremely precisely and quickly, even if surface characteristics like colour or reflectivity are changing. Parameters such as measurement speed or filters are handled directly in the sensor's DSP.

New Thin Current Transformers
Pearson Electronics has recently designed several new current transformers with a thickness that is about 1/2 of the size of the in stock current transformers designed by Pearson. The thin model 8105-03 is shown below next to our in-stock model 2878. These new ultra thin current transformers allow a more compact installation resulting in lower circuit inductance. Apertures range in size from 0.25 inches to 2.0 inches and the models have the same footprint as our in stock current transformers, except for thickness. Designs include BNC and SMA connectors depending upon the model.
These ultra thin designs incorporate Pearson’s wide-band frequency response and 1% accuracy, or better, across the mid-band. The model 8105-03 has a 0.25 inch aperture, a 0.1 V/A transfer impedance with a 3 dB bandwidth from 50Hz to 40MHz. The maximum rms current rating is 6 Amperes. Peak currents up to 300 Amperes and rise times as short as 5 nanoseconds can be viewed faithfully. Contact us for a complete listing of the ultra thin current transformers.

Channel Electron Multiplier arrays
In addition to the standard CEM models, we also offer flat rectangular CEMs which can be stacked together to form arrays and which allow simultaneous measurements and read out of several sensors. The metalized contact areas are usually deposited on the narrow under and upper side of the CEMs. The outputs and therefore the anodes for CEMs smaller than 4 mm are positioned off-center. This increases the distance between adjacent anodes and therefore reduces possible crosstalkbetween the signal lines.
More information on many different types of CEM arrays.

New Tiny Silicon Thermopile with high performance.
Alrad Electronics has announced the introduction of the ST120, a small thermopile detector that offers high output in a silicon-based chip. Developed by Dexter Research in the USA using their industry-leading internal optimization program, the ST120 is believed to outperform any competitor with same active area.
The new single-channel silicon-based thermopile provides lowest cost solutions in a small active area of 1.2mm x 1.2mm in a TO-5 package. Performing at a time constant of 25ms with nitrogen encapsulation gas, the ST120 delivers a very low Temperature Coefficient of Responsivity of minus 0.04%/°C. This detector has a very short thermal shock response to ambient temperature change.
The new device is available with many of the long list of optical filter options. An optional Internal 30kW 5% NTC chip thermistor provides ambient package temperature measurement. Also available, an internal aperture precisely defines active area for applications with field-of-view and/or spot size requirements.
The company believes that the ST120 will become the preferred detector for gas analysis. It is well suited to multi element applications, and is excellent for non-contact temperature, fire suppression, and for use as a horizon sensor.
A volume manufacturer, as well as the global centre of expertise for infrared detectors since 1977, Dexter Research Center, Inc., Dexter, Michigan, offers 30 models and over 600 products, which is believed to be more than all competitors combined. Enjoying record growth in 2005, Dexter Research continues to lead the industry in the design, development and production of high quality, high output thin film and silicon-based infrared sensing thermopile sensors.
