Strain Gauge Reader for Geotechnical and Structural Monitoring
In geotechnical and structural monitoring sites, obtaining reliable data from buried strain gauges is not an easy task. Environmental interference, wiring hassles, drifting readings—these issues often cause headaches for engineers. Kingmach's strain gauge readouts are designed to address these practical issues. It is not a precision toy in the laboratory, but a tool that can work stably on construction sites, tunnels, and slopes. We have been making monitoring instruments for many years and know what users need: simple operation, reliable data, and someone to take care of any problems. This reader can directly connect to common vibrating wire and resistive strain gauges and automatically identify parameters, eliminating the trouble of manual settings. The battery lasts all day and the screen is legible in sunlight. After on-site measurement, the data can be saved and exported for analysis later. If you have a special project, we can also customize functions or interfaces as needed. In practice, make on-site readings less fussy and more confident.
Technical Detail
Kingmach's strain gauge readers are data acquisition tools designed for on-site monitoring tasks. It can match most vibrating wire and resistive strain gauges and automatically identify sensor types and coefficients, eliminating the need for manual entry. The reader has a built-in temperature compensation algorithm, which can reduce errors caused by drift in outdoor environments with large temperature differences. The screen backlight is adjustable and the readings can be read clearly even under strong light. A single charge can support continuous measurement for a whole day, meeting routine field operations. The built-in memory of the device can save thousands of records, which can be exported to the computer through the USB interface and used for data analysis with the software we provide. In order to adapt to different projects, this reader also provides a multi-channel version, which can collect data from multiple measuring points at the same time. As a manufacturer, we can directly provide a combination of sensors and readers to ensure matching and stability from sensing elements to data collection. In case of technical issues, our team of engineers can provide remote support or on-site service. Whether it's tunnel convergence monitoring, slope stress analysis, or structural health assessment, this reader pursues one goal: making work on site smoother.

Currently, it supports vibrating wire and resistive strain gauges, and most of these sensors on the market can be connected. If you encounter a special model, we can help adjust parameters or customize the interface.
Connect to the computer through a USB cable, and use our software to directly read the stored data and export it to CSV or Excel format for subsequent processing.
When fully charged, it can work for about 8 to 10 hours of continuous measurement, which is enough for field work during the day. It is recommended to bring a power bank as a backup.
We will calibrate before leaving the factory and attach a calibration certificate. If it is a long-term project, you can return to the factory for calibration regularly, or we can guide you to self-calibrate on site.
There are single-channel and multi-channel versions. The multi-channel version can collect 4 or more measuring points at the same time, and the specific number of channels can be customized according to project requirements.
