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.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
