Mark sensor

Mark sensors are devices used in industrial applications to detect the presence or absence of a mark on a surface. These marks can be in the form of labels, codes, or other indicators that help with positioning, alignment, and quality control in manufacturing processes. Mark sensors use various technologies such as optical, ultrasonic, capacitive, or magnetic to detect the marks accurately and quickly.

Applications

▶Labeling and packaging: Mark sensors are used to detect labels on products or packaging materials to ensure proper labeling and packaging alignment.

▶Printing and coding: Mark sensors are used in printing and coding machines to detect printed marks on products for accurate printing and coding.

▶Assembly line: Mark sensors are used in assembly lines to detect marks on components for proper assembly and alignment.

▶Quality control: Mark sensors are used in quality control processes to detect defects or missing marks on products.

Radar Level gauge

The LXD series is FMCW radar operating at 76-81 GHz, which has a maximum measuring range of 120m and a minimum blind zone of 8cm. It supports 4-wire and 2-wire applications. Higher operating frequency and shorter wavelength make it ideal for solid applications, including those with extreme dust and high temperature to + 200℃. The radar consists of an electronic circuit coupled to a lens antenna and flange for quick and easy positioning.  

The main benefits of using 78 GHz over devices using lower frequency are: 

Based on the self-developed CMOS millimeter wave RF chip, a more compact RF architecture, a higher signal-to-noise ratio, and a smaller blind zone are realized.

5GHz working bandwidth means higher measurement resolution and accuracy.

3°antenna beam angle, so the interference in the environment has less impact on the instrument, and the installation is more convenient.

Shorter wavelength yields good reflection properties on sloped solids, so aiming towards material angle of repose is usually not necessary.

Support remote debugging and remote upgrading to reduce the cost of field personnel.


LXD series supports 485 bus protocol (4-wire), serial-port (2-wire) protocol, and hart (2-wire) protocol. It is very easy to install and configure via an optional graphical local display interface on PC. Or you can modify the built-in parameters either locally via the push buttons. Or you can use cell phone to control LXD series via Bluetooth.
