Capacitive proximity/level sensor


Senyd capacitive proximity sensor is a type of sensor that detects the presence or proximity of an object without physical contact. It works by generating an electric field and measuring changes in capacitance when an object enters the field. When an object comes close to the sensor, the capacitance changes, triggering the sensor to detect the object's presence.Capacitive proximity sensors are commonly used in various applications, such as object detection, liquid level sensing, and touchless interfaces. They are preferred for their non-contact operation, high sensitivity, and ability to detect a wide range of materials, including non-metallic objects. These sensors are used in industries such as automotive, food and beverage, and manufacturing for automation and control purposes.

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.
