load cell sensitivity

Sensitivity is how much electrical signal you get for a given load. For example, a 100 kN load cell with 2 mV/V sensitivity and 10V excitation will output 20 mV at full load. That signal has to be read by your logger or transmitter, so matching the range is key. Lower sensitivity might need a better amplifier; higher sensitivity could clip the input if not careful.

Check your data logger’s input range first. If it accepts 0–20 mV full scale, a standard 2 mV/V load cell with 10V excitation fits perfectly. For long cable runs, consider higher excitation or a load cell with frequency output, like vibrating wire, which doesn’t degrade with cable length. Kingmach offers both resistive and vibrating wire options so you can match the site conditions.

Not directly. Accuracy depends on combined errors: nonlinearity, hysteresis, creep, and temperature effects. A high-sensitivity load cell might give a stronger signal, but if it drifts with temperature, your field data suffers. Kingmach’s specifications show all these factors, so you can evaluate total accuracy rather than focusing on sensitivity alone.

Yes, all load cells have a temperature coefficient of sensitivity. For resistive cells, it’s typically ±0.005% of reading per °C. Over years, drift might happen, especially in high-humidity or cyclic loads. Kingmach uses sealed gauges and stress-relieved designs to minimize this. Regular recalibration is still recommended, especially after the first year of installation.

Kingmach’s standard resistive load cells are usually 2 mV/V, but we can customize from 1 mV/V for high-capacity cells to 4 mV/V for low-force applications. For vibrating wire sensors, sensitivity is given in Hz/kN, and we can adjust the wire tension to match your readout frequency range.
