Vibrating Wire Strain Gauges for Bridge, Tunnel & Dam Monitoring: Complete Selection Guide
The global construction industry is experiencing a massive surge in large-scale infrastr...
Portable Vibrating Wire Dynamic Strain Data Logger
Portable Vibrating Wire Dynamic Strain Data Logger
Most vibrating wire loggers on the market focus on static readings—slow, stable measurements once every few minutes. That works for long-term settlement or creep monitoring, but it misses the snapshots that matter when a structure sees sudden load shifts, vibrations, or cracking. A portable dynamic strain logger fills that gap, capturing rapid strain transients while still supporting conventional static surveys. In the field, portability and sensor compatibility often determine how quickly you can cover a monitoring grid or redeploy after an event. Kingmach’s unit brings these capabilities into a single hand-carried logger, aimed at geotechnical engineers who need both fast sampling and broad sensor support without hauling multiple boxes to site.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
The logger handles vibrating wire strain gauges along with common thermistor-based temperature compensation, sampling at user-adjustable rates high enough to resolve dynamic strain events like pile driving impacts or blast vibrations. Its channel count and storage are designed for extended standalone use, and data offload happens over a standard interface—no proprietary cables needed. Built around field conditions, the enclosure is rated for outdoor exposure, and internal power management stretches battery life through typical survey schedules. Compatibility covers mainstream gauge models from manufacturers like Geokon, RST, and Soil Instruments, so teams can mix existing inventory without swapping readout units. Kingmach backs the unit with direct technical support and calibration services; the company’s distribution network spans regions where these instruments see heavy use, from tunnel projects in Southeast Asia to dam safety in South America. For long-term monitoring projects, the logger can be integrated into automated data acquisition systems, bridging the gap between manual spot checks and permanent installations.

Common technical questions
Can this logger read standard vibrating wire strain gauges from Geokon or RST?
Yes, it supports the frequency ranges and coil impedances of most commercial gauges. If you have a specific model, supply the datasheet and we can confirm compatibility before shipping.
What is the maximum dynamic sampling rate?
The sampling rate is user-configurable. For dynamic readings, it can be set fast enough to capture typical transient events—impact, blasting, or rapid load testing—but exactly how fast depends on channel count and sensor characteristics. Contact our support team with your target event duration to get a practical configuration.
How is data downloaded in the field?
Data transfers via a standard USB or SD card interface. No dedicated reader box or proprietary software is required; files can be opened directly in common analysis packages. Field crews typically dump data to a laptop or tablet at the end of a shift.
Does it do static readings as well, or is it only for dynamic monitoring?
It handles both. You can run it in low-power static mode for long-term monitoring, then switch to dynamic mode when specific events are expected. Many users keep it for mixed survey work—checking static baselines and capturing occasional dynamic incidents.
What kind of battery life can I expect in the field?
Battery life varies with sampling rate and channel count. In static mode with hourly readings, it can last weeks. Running continuous dynamic sampling on multiple channels will shorten that significantly, so power planning is project-specific. The logger runs on easily replaceable battery packs, so you can swap in the field.
