full bridge load cell

The full bridge load cell is the workhorse of precision force measurement. At its core, four strain gauges are bonded to a machined steel element and wired in a Wheatstone bridge. When force is applied, two gauges stretch and two compress, generating an output proportional to the load. This arrangement cancels out temperature errors and nearly doubles the sensitivity compared to a quarter bridge. Typical specifications for Kingmach full bridge load cells include a rated output of 1.5–2.0 mV/V and a combined error band of 0.03% of full scale, depending on the model. Kingmach builds these sensors from high-grade alloy steel or stainless steel, with environmental protection up to IP68 for submerged conditions. Cable options include PUR-jacketed braided shields for extended outdoor life. Connection is straightforward via standard 6-wire circuits, which remove lead resistance errors. For setups that need digital output, we pair the load cells with compatible signal conditioners and data loggers, often from our own range of monitoring instruments. One thing we’ve learned from supplying monitoring networks is that no two projects are alike. So beyond the standard catalog, Kingmach offers custom capacity ranges (from a few hundred kilograms to over 3,000 kN), bespoke base plates, and high-temperature variants. Each sensor comes with a calibration certificate traceable to national standards. And with distribution partners in over 30 countries, we can deliver quickly and provide local technical support. If you need a full bridge load cell that fits into a larger data collection system, just let us know the interface—we’ve done Modbus, 4-20mA, and other common industrial protocols.
