strain gauge data acquisition

Kingmach strain gauge data acquisition modules are designed to connect directly to standard foil and vibrating wire strain gauges, as well as load cells and pressure transducers. Each channel supports quarter, half, and full bridge configurations, with selectable excitation voltages from 2.5 V to 10 V. On‑board 24‑bit ADCs sample at user‑set rates between 1 Hz and 100 Hz per channel, which covers both static monitoring and slower dynamic events like rail traffic or pile driving. The input impedance is kept above 10 GΩ to handle high‑resistance gauges without parasitic loading, and shunt calibration is built in so you can verify the chain without hanging a precision resistor across the terminals.

Because many geotechnical installations mix sensor types, the same hardware accepts 4–20 mA, 0–5 V, and thermistor inputs—so one box can pull in strain, temperature, and displacement data. The firmware treats each reading with adjustable digital filtering, and the processed output comes out as Modbus RTU, SDI‑12, or plain ASCII strings over RS‑485. That makes integration straightforward with third‑party loggers, radios, or PLCs.

Kingmach offers stock enclosures rated IP65 for standalone use, and we regularly build custom terminal panels and rack‑mount versions for larger projects. Our engineering team can adjust gain ranges, add isolated inputs, or change connectors to match existing site cabling. With a distribution network across more than 40 countries, on‑site startup help and remote diagnostics are within reach, not an afterthought.
