load cell force transducer

A compression load cell measures pushing forces and often sits under a bearing plate or jack. A tension type handles pulling forces, commonly inline with anchors or tiebacks. Kingmach supplies both, and many of their annular transducers can measure tension as well as compression when mounted between anchor head and stressing chair.

Yes. Kingmach regularly adapts inner diameter, outer shape, and height to fit specific jack clearances or anchor configurations. They can also match the electrical connection type—weatherproof connectors, armored cable length, or loop-powered outputs—to site requirements without long lead times.

A practical rule is once a year for long-term installations, or after any overload event. Transducers with minimal drift and robust sealing, like those Kingmach ships, can stretch calibration intervals slightly if you track zero-shift trends. The calibration service is available through their support network, often with turn-around within a few weeks.

4-20 mA current loops are common because they handle long cable runs without signal loss and power directly from the logger. RS485 digital output gives easier multi-sensor networks. Kingmach offers both, plus standard mV/V for systems that already have signal conditioning. The choice often comes down to what your datalogger accepts.

Start with the maximum expected working load, then add a safety factor—typically 20-30% for static loads, higher for dynamic loads like pile driving. Your load cell should not be routinely stressed near its full scale, as that can accelerate drift. Kingmach engineers can help size the transducer based on your structural design values and installation constraints.
