load cell amplifier

Kingmach builds the load cell amplifier with geotechnical applications in mind. It powers strain gauge-based sensors with a stable excitation voltage—often selectable between 5V and 10V to match different load cell specifications—and amplifies the returning millivolt signal to a standard analog output, commonly 0–10V or 4–20mA. This makes integration with most data acquisition systems straightforward. The gain can be set via DIP switches or jumpers, allowing one amplifier model to accommodate load cells with varying sensitivity ranges from 1 mV/V to 4 mV/V. Calibration is done with known shunt resistors, so you can verify the setup without needing physical weights every time. A low-pass filter is built in to suppress 50/60 Hz noise, which helps when cables run next to power lines. The aluminum enclosure is sealed against dust and splashes, rated IP65, and features robust terminal blocks that accept ferrules—details that matter when installations are long-term and weather-exposed. Common uses include tieback anchors, retaining walls, and tunnel linings, where load cells are installed and left to operate for years. Kingmach supplies these amplifiers globally, with engineering support available for configuration questions.
