strain gauge load cell sensor

A strain gauge load cell converts force directly into an electrical signal via foil strain gauges bonded to a spring element. Compared to hydraulic cells, they don’t need messy oils and are easier to interface with digital readouts. Vibrating wire cells are often used in geotechnical applications, but strain gauge cells offer faster response and simpler data acquisition. Kingmach’s cells are designed to work well with common logging systems, making them a practical choice for dynamic or long-term monitoring.

Yes. We have a custom engineering team that can adjust the load cell’s measuring range, physical size, cable exit, and mounting details. If you need a pancake load cell with a center hole for an anchor bolt, or a tension link sensor for cable monitoring, just provide your specs. We also do custom output signals or special temperature ranges.

Our standard outputs are mV/V or amplified options like 4-20mA and RS485. Most data loggers and PLCs can read these directly. We provide wiring diagrams and setup guides, and if you’re using a popular geotechnical logger from companies like Campbell Scientific or In-Situ, we can help with the configuration. Many customers just connect through a junction box to their central readout.

Typical accuracy is ±0.1% of full scale, and many of our sensors achieve ±0.05% with careful calibration. Long-term drift is minimal when the sensor is installed correctly and not overloaded. We recommend annual recalibration for critical applications, and we offer that service. The metal body and sealed construction protect the gauge from environmental creep.

Absolutely. We seal our strain gauge load cells to at least IP67, which means they can handle temporary submersion and heavy rain. For submerged applications like underwater anchor monitoring, we have IP68 vented cable options. The stainless steel versions are particularly good for corrosive settings near saltwater or mining chemicals.
