Load cells are transducers that convert force into an electrical output. There are several types categorized by their construction, method of operation, or output signal.

To provide excitation to the load cells and measure the voltage output, you usually want to use an amplifier to condition the circuit.

If the force is too low, the signal output may be too small to measure. So, because of these restrictions, load cells are manufactured with a range of maximum working force (MWF) ratings.

Full-scale output range is typically 2,000 mV, 10 times that of traditional strain-gage load cells. Typical sensitivity is 40 mV/lb, with response times of 20 msec and large signal-to-noise ratios.

Forty 10-ton wireless compression load cells from Straightpoint were used to monitor forces on temporary shoring columns used to support two tower cranes during the Century City Mall project on ...
