Laser measurement
The Opto NCDT 1400 Series Laser is said by its manufacturer to be the smallest CCD technology laser in the world. Signal conditioning is performed in the laser head, rather than in a separate controller, and the laser unit is self contained so it can be replaced individually. The product's ME-CCD technology is said to allow for inexpensive, non-precise fixturing up to 308 from perpendicular. "This is a small, reasonably priced, adaptive, total measuring system," says Carnegie Mellon's Lawrence Cartwright. "It has very good static and dynamic resolution and can be used in numerous measuring environments. With a sampling rate of 1 kHz, it has the potential for providing accurate deflections in low-frequency cyclic testing."

Photoelectric
sensors
Because the housing of WORLD-BEAM™photoelectric sensors fits most mounting requirements, the 1.38×0.59×1.22-inch devices can replace hundreds of sensor styles and designs. A 0.7-inch threaded nose lets the sensor replace 0.7-inch-diameter barrel sensors; the standard mounting hole configuration lets it directly replace numerous nonthreaded rectangular sensors. Specs include: 67-ft opposed-mode sensing range, 19.8-ft retroreflective-mode range, and regular and proximity modes with ranges up to 18 inches.

Data
logger
Part of the personalDataRAM family of aerosol monitor/data loggers, the pDR-1200 uses an attachable pump module or separate sampling pump to perform real-time particle-size-selective measurements. A filter holder located downstream of the photometric sensing stage allows concurrent gravimetric measurements or subsequent chemical analysis of collected samples. Applications include: continuous emissions and test-chamber monitoring as well as respirable, thoracic, and PM25 monitoring.

Soft
starter
By using 24V dc control power, Intelligent Technologies (IT) Soft Starters are intrinsically safer than 120V ac models, simplify compliance to safety standards, and offer more reliable interfacing with PLC and distributed control logic systems. The small solid-state device integrates the bypass contactor and overload relay functions, which eliminates the need for separate hard-wired devices. Control features include kick start, which provides an adjustable pulse of up to 550% current or 85% torque for up to 2.0 seconds, and soft stop, which ramps down motor voltage for an extended coast to rest.
