efector inc. introduces the new LR Series level
sensor for monitoring liquid level in tanks for applications that include parts
cleaning, coolant monitoring, water treatment and hydraulic power units. The modular system consists of a
compact, stainless-steel sensor housing with numeric display and pushbutton setup,
a cut-to-length stainless-steel measuring probe that easily attaches to the
sensor housing, and an M12 cordset for power and outputs.
LR level sensor can detect a variety of liquids that include water and water-based
media such as coolants, cleaning agents and paint. For oil and low-dielectric
fluid applications, ifm offers a coaxial tube that slips over the measuring
probe to provide reliable level sensing. With no moving parts, the
maintenance-free level sensor does not need routine cleanings and offers a long
ifm offers measuring probe lengths up to 63 inch for deep tank
applications. Parameters such as liquid type, setpoint and resetpoint are
established using the menu-driven display. The sensor does not have to be installed in the process to
set the parameters. Level readings can be displayed in inches or centimeters on
the sensor's four-digit display. Bright LEDs indicate
the switching or analog output.
The LR sensor's measuring principle is echo time-of-flight
using guided wave radar technology to detect liquid level. This technology enables a strong
signal strength and the ability to ignore build up.
The Micro dc units are available
with two or four switch points and a scalable analog output. Starting list
price for a complete system is less than $500.
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.
