Terminal Boxes for Load Cells: Functionality, Types and Benefits!

Load cell junction boxes are an important component in weighing systems. Totalizers provide a reliable connection between load cells and measuring instruments, weighing terminals, transducers, display units, measuring devices, and also offer various options for functionality depending on the needs of a particular weighing system.

1. Analog terminal junction boxes for strain gauges: Analog terminal junction boxes are designed to connect and process analog signals from strain gauges. They are equipped with inputs for each load cell that accept analog voltage or force values. The boxes also have output terminals that provide signal transmission to measuring devices or other data processing systems.

2. Digital junction boxes for load cells: Digital junction boxes offer the possibility of connecting load cells using digital communication protocols such as RS-485. They transmit data in digital format, which reduces the possibility of interference and provides a more reliable connection. Such boxes usually have built-in ADCs (analogue-to-digital converters) to convert analog signals to digital format or connect all digital load cell signals, data is exchanged via the RS485 port with each load cell and converter.

  3. Load Cell Summing Terminal Boxes: The load cell summing terminal boxes are designed to combine signals from multiple load cells into one output signal. They have inputs for each load cell and trim potentiometers that allow you to adjust and adjust each sensor individually. This functionality allows you to fine-tune and match each load cell to achieve optimum measurement accuracy and reliability. Summing terminal boxes are especially useful in applications that require the simultaneous measurement of force or load from multiple points.

4.Number of Load Cell Outputs: The terminal junction boxes are available in a variety of designs with different numbers of load cell outputs. Common options include boxes of 4, 6, 8, 10 and 12 load cells. This allows you to connect the right number of sensors depending on the specific needs of weighing systems.

5. Terminal boxes, adders for strain gauges come in different designs and are made of different materials:

Plastic: Plastic boxes offer lightness, good insulation and corrosion resistance. They can be an economical solution for weighing systems, platform scales, weighing bins. Stainless Steel: Stainless steel boxes have high strength, corrosion resistance and a good degree of protection against external influences. This makes them suitable for use in harsh environments or high humidity conditions. Dural: Boxes made of duralumin, or aluminum alloy, are lightweight and durable. They are widely used in applications where a strong and lightweight construction is required. Lightning Proof and Explosion Proof: Some terminal junction boxes may be specially designed for hazardous areas or lightning protection. These designs provide safe and reliable operation in explosive or thunderstorm environments.

6. Variety of terminal box manufacturers: There are many manufacturers of load cell terminal junction boxes in the market. Here are some of them:

CAS: CAS offers a wide range of terminal boxes with different configurations and functionality.

Zemic: Zemic specializes in the production of high quality load cell terminal boxes with various connection and protection options.

Keli: Keli offers reliable and durable terminal junction boxes with high measurement accuracy and stability.
