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.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
