Inductive sensor detects the position of objects through the use of a resonant
positioning device. An emitter/receive coil system generates a high-frequency alternating magnetic field that activates the
resonator integrated into the positioning device. Each time the
transmitting coil stops transmitting, the resonator induces voltage into two
receiving coils inteÂgrated into the sensor. The voltage intensity depends on
where the positioning device overlaps the receiving coils. An integrated 16-bit
processor provides a corresponding proportional output signal in different formats:
0 to 10V, 4 to 20 mA, IO-Link or SSI. The
Linear Inductive position sensor was designed to have extremely short
blind zones of only 29 mm on each side, along with a wide temperature range of
-25 to 70C and the option to adopt the sensor by programming it to different
measuring ranges, allows users to dispense with special variants for specific
applications. Using only one sensor family for measuring ranges between 100 and
1,000 mm simplifies warehousing and helps users reduce their total cost of ownership.
LI sensors for position detection is favorable over potentiometric or
magnetostrive devices due to their high accuracy (1 Âµm) and mid-range
price-tag. Although there are several options for position detection - ranging
from analog sensors, to incremental devices, to digital switches - not all of
these can be easily applied to short-range and long-range applications. Also,
unlike magnetorestrictive devices, TURCK's new Linear Inductive position sensor
does not use magnets. Magnetostrictive
and other similar technologies use magnets in their design that can experience
electromagnetic interference in industrial environments.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
