Vibrating Wire Data Logger

The CA-VWLog-8 multi-channel data acquisition instrument (hereinafter referred to as the acquisition instrument) is an enhanced 8-channel vibrating wire data logger. Its main core uses a 32-bit ARM Cortex-M3 CPU chip with a very high cost-performance ratio in the industry, which both guarantees the timeliness of data acquisition and completeness of functions and takes into account the overall cost of the device itself. Thanks to its own architecture, the acquisition instrument is suitable for automatic acquisition of frequency and temperature from vibrating wire sensors, whether in a single unit or in a multi-unit network, or for acquiring data from RS485 bus type sensors using different function modules, allowing it to adapt to various complex working conditions.
