After purchasing one RDDLZ load cell, you can buy a special digital display controller to obtain readings directly, or buy a transmitter to output standard signal to PLC, DCS and other systems. Customized output signal is 0-5V, 0-10V, or 4-20mA.

Note: The load cell cannot be connected to both the transmitter and the controller at the same time — only one can be selected.

Digital load cell weight sensor are available in multiple measurement ranges: 0-350kg. They support two output options: RS485 and RS232, with a high accuracy of ±0.05% and a 150% F.S safety overload.

Application

Tips: How does an RS485 digital load cell differ from an RS232 load cell?

RS485 and RS232 are both serial communication protocols used in digital load cells, but they differ in performance, distance, and application:

RS232 (Short-Distance Communication):

Supports point-to-point communication (one load cell to one device).
Transmission distance is limited to around 15 meters.
Commonly used for single-device connections, such as computers or display units.

RS485 (Long-Distance & Multi-Device Communication):

Supports multi-drop networking (one load cell can communicate with multiple devices).
Transmission distance extends up to 1200 meters, making it ideal for large-scale industrial applications.
More resistant to electrical interference, ensuring stable data transmission in noisy environments.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
