Fiber optic sensor


Senyd fiber optic photoelectric sensor is a type of sensor that uses fiber optic technology to detect the presence or absence of an object. These sensors work by transmitting light through a fiber optic cable and detecting changes in the amount of light that is received at the other end. When an object is present, it can block or reflect the light, causing a change in the signal received by the sensor. Fiber optic photoelectric sensors are commonly used in industrial automation applications where high accuracy and reliability are required. They are ideal for applications where traditional sensors may not be suitable due to factors such as electromagnetic interference, harsh environments, or the need for long-distance sensing.

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.
