vMeas - Modular Data Acquisition

vMeas Standard

The vMeas standard is a self contained, ultra-portable data acquisition system providing dynamic data capture. It is effective in various field, mobile and test facility applications. This system includes four analogue input channels, a tachometer and an analogue output. All data can be streamed and saved to a laptop or PC via USB connection, with hard disk and SSD parallel compatibility. Synchronous working 24-bit analogue-to-digital converters for each channel provides wide dynamic range. The frequency range is from 1Hz up to 20kHz with increments of 1, 2 and 5 Hz. The anti-aliasing filters are automatically set to the selected frequency range. The input coupling is DC, AC or IEPE for sensors that need a constant current source.
