USB-based data acquisition for all measured quantities

Despite their small size and inexpensive price, the USB data acquisition modules offer very high quality and performance capability, such as carrier frequency technology and A/D converter with 24-bit resolution. Modules can be supplied as units that draw power from the USB interface or that utilise a separate power supply.

The amplifiers are designed 'plug-and-measure' units while fully synchronised measurement systems can be enabled by operating several measuring amplifiers via a USB hub. This means that users can obtain measurement results extremely rapidly.

To simplify set-ups, espressoDAQ measuring amplifiers support TEDS (Transducer Electronic Data Sheet) technology, which enables easy and rapid configuration of a wide range of transducer types (transducers are connected via RJ45 connectors that can be installed in the field without the use of specialist tools).

HBM supplies the espressoDAQ USB amplifiers with simple-to-operate software that requires only a few steps for configuration, data acquisition and visualisation, thereby enabling measurement results to be obtained very quickly. Measured data can be exported using a choice of popular formats.

Simple operation, high performance

Marc Zuern, HBM's product manager, comments: "The espressoDAQ platform takes full advantage of USB technology to give measurement technology that is simple to operate and has high performance capability."

Portable applications can be implemented through direct operation with a measuring amplifier. Zuern adds: "The system is suitable for a wide range of applications such as test engineers operating in the field or newcomers to measurement technology that want to achieve measurement results rapidly and easily."

The modules enable the measurement of individually configurable current or voltage inputs, along with measurement using strain gauges (SG) - both in half- or full-bridge circuits - and connection of all types of thermocouples.

Modules are available with either four or eight inputs that are all electrically isolated individually and from each other. Each channel has its own A/D converter for absolute synchronous measurements.

Typical applications for espressoDAQ modules are, for example, in the service sector where measurements can be easily and rapidly implemented with a laptop and a small module. The espressoDAQ modules are said to be suitable for applications where larger measurement systems would be too complicated and expensive.
