常见问题

Why are specialized cables needed for load cells instead of regular electrical cables?

Load cells output very low-level analog signals (typically 2-3 mV/V) that are highly susceptible to electrical noise, attenuation, and interference. Specialized cables provide multiple shielding layers, precise impedance matching, and environmental protection that regular cables lack, ensuring measurement accuracy.

What is the difference between 4-wire and 6-wire load cell cables?

4-wire cables have two wires for excitation voltage and two for signal output. 6-wire cables add two sense wires that allow the instrument to compensate for voltage drop in long cable runs, providing more accurate excitation voltage at the load cell itself, especially important for precision measurements over distances.

How does cable length affect load cell measurements?

Longer cables increase resistance in the excitation circuit, potentially reducing the actual voltage at the load cell and affecting output signal. They also increase susceptibility to noise. Using proper gauge wires, 6-wire systems for compensation, and high-quality shielding minimizes these effects in long cable runs.
