Overview

VW Gauge Monitor is a vibrating wire datalogger. It measures the frequency and thermistor temperature signals from vibrating wire sensors and records them for long-term monitoring in the field.

NB-IoT communication sends measurements to the “dot” cloud server for remote monitoring. Internal flash memory stores more than 1 million recorded data points, so readings are kept on the unit as well. Two 18650 Li-ion batteries power it, with an optional solar charger, and the IP65 enclosure is built for field and civil engineering deployments.

Key features

  • NB-IoT wireless communication

    Sends measurement data to the "dot" cloud server for remote monitoring.

  • MQTT, TCP/IP and Modbus protocols

    Supports data acquisition and integration with compatible monitoring systems.

  • Low-power operation

    Two 18650 Li-ion batteries, based on one measurement per hour. Optional solar charger.

  • Storage

    Internal memory, with optional external memory.

  • Simple configuration

    Data transmission is set through settings stored on the SD card.

  • Rugged construction

    IP65-rated enclosure.
