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...
Kingmach Wireless Voltage Data Logger
wireless voltage data logger
When a piezometer or load cell in a remote dam starts delivering erratic readings, the root cause is often unstable supply voltage. Kingmach’s wireless voltage data logger tackles this by continuously recording 0–5 V or 4–20 mA signals and pushing data through cellular or LoRa networks—so you can spot voltage drifts before they ruin sensor accuracy. You set the logging rate, define alarm thresholds for low voltage events, and let the logger store months of data locally as a fail-safe. Because the unit is fully wireless and battery powered, there is no need for trenching or long cable runs, which simplifies installation in boreholes, slopes, and tunnels. The data appear in your existing monitoring dashboard or Kingmach’s software, making integration a matter of configuring an API endpoint. Whether you are monitoring a few points or a large array of vibrating wire sensors, this logger gives you the technical visibility that manual checks simply can’t match.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Built for geotechnical and structural monitoring, Kingmach’s wireless voltage data logger accepts standard 0–5 V, 0–10 V, and 4–20 mA signals from sensors like strain gauges, pressure transducers, and displacement meters. A 24-bit ADC ensures fine-grained recordings even at low signal levels, while configurable sampling intervals let you balance data resolution against power consumption. The sheet-metal enclosure holds an internal battery pack that runs for months at hourly logging rates, and there is an option for an external solar panel or DC supply for indefinite field runs. Data transmission choices include 4G/LTE, NB-IoT, and LoRaWAN; a local microSD card stores up to a year of readings as backup. Through Kingmach’s web platform, you can push data to third party SCADA or FTP servers via MQTT or SQL interfaces. As a professional manufacturer of geotechnical instruments, Kingmach can tailor channel counts, input types, and enclosure IP ratings to match specific project needs. A global distribution network and local technical support teams ensure that setup questions are answered quickly, and on-site calibration services can be arranged where needed. The logger ships with an intuitive PC utility for first configuration and a cloud dashboard for ongoing review of voltage trends and alarm histories.

Common technical questions
What input ranges does the wireless voltage data logger support?
Standard models handle 0–5 V, 0–10 V, and 4–20 mA signals, covering most geotechnical and industrial sensors. If your project uses a different range, Kingmach can customize the input conditioning circuit to match.
How is data transmitted, and can I integrate it with our existing SCADA system?
Data can be sent over 4G/LTE, NB-IoT, or LoRaWAN. Integration is straightforward—the logger can push readings directly to your SCADA via MQTT, SQL inserts, or CSV uploads to an FTP server. Kingmach’s support team helps configure the endpoint during setup.
What is the typical battery life, and are there external power options?
On internal batteries, expect several months of operation at hourly logging, depending on signal strength and report frequency. For permanent installations, we offer a solar panel kit or a DC input option that keeps the logger running without battery swaps.
How many sensor channels can one logger record?
The base unit typically provides one or two differential channels, but multi-channel expansions are available. Because Kingmach designs and manufactures in-house, we can build loggers with up to 8 channels to suit larger monitoring arrays.
