Enhanced incremental encoders

Rockaway, N.J.— Incremental encoders from Euchner provide rotary and linear displacement using a long-life LED light source with Opto-ASIC receiver and operate at a voltage of 5-30 V dc. Standard operating temperatures range from –40 to +80 °C, and these devices have an environmental protection rating of NEMA 4 (IP65).

Step motor now has encoder

Hauppauge, N.Y.— Turbo Disc disc magnet step motors are now available with the A22 incremental encoder. This combination provides and alternative to brushless motors by using the A22 to supply commutation as well as position information. Turbo Disc motors provide up to 200,000 rad per sec., and a top speed of 15,000 rpm.

Absolute angular encoder

Schaumburg, Ill.— Providing capabilities previously unavailable to the angular encoder market, RCN 723 has a resolution of 0.15 angular sec in combination with system accuracy of 2 angular sec. Operating on the photoelectric principle of scanning 131,072 grating periods (17 bits in gray-code evaluation), this track is subdivided 64-fold to achieve 23 bits, resulting in 8,388,608 absolute...

Rate/RPM/Frequency Input DPM

Tucson, Ariz. —Model 210 digital panel meter accepts input signals from magnetic pick-ups, photocells, encoders, proximity detectors, transmitters, and power lines. Its Frequency-Voltage technique converts these inputs to a 0-2 V dc for the 4.5 digit A/D. The F-V system allows frequency measurement and control without the need for specific gear ratios.

Ultrasonic Proximity Sensors

Newton, Pa. —SonicLaser ultrasonic proximity sensors come in 18 models and feature a narrow, concentrated beam angle 2.5° off-center axis. This narrow beam angle is said to render the sensor insensitive to echo interference from surrounding objects. Measuring ranges vary from 3.28 to 26.25 ft.

High Accuracy with Mini Encoders

Allerod, Denmark— Using the latest SMD and bonding technology, these miniature hollow shaft encoders are made with an outer diameter of only 24 mm, and are especially resistant to shock and vibration. They count 2,000 pulses per revolution and a maximum frequency of 200 kHz. Counting the leading and trailing edges of both channels provides four times the resolution, which means that the ...

Corrections – 1998-02-01

In the November 1997 Control Engineering cover article, "Flow Sensing: The Next Generation," Fluid Components International was incorrectly named on page 62.On page 64, in the sidebar "Flow Conditioners Save Piping," Vortab Co. should have been shown as based in San Marcos, Calif. Sam Kresch, Vortab marketing manager, cited a Southwest Research Institute (San Antonio, Tex.
