Rugged distributed data acquisition solution with TSN

18 December 2017

NI has introduced a new range of rugged, distributed and synchronised FieldDAQ devices which utilises Time Sensitive Networking (TSN).

Test engineers are moving away from the use of centralised measurement systems that can be susceptible to noise, and toward distributed measurement nodes, in which the digitisation and signal conditioning occurs as close to the sensors as possible.

Yet more distributed measurement topologies create new challenges. This means that not only must DAQ devices withstand harsh test environments, they must also acquire synchronised data over an entire system and scale and integrate seamlessly.  

NI’s new FieldDAQ devices are said to be the company’s most rugged DAQ devices. They can acquire accurate, reliable measurements in the most severe test cell and outdoor environments, including rain, sleet, snow or mud. FieldDAQ devices have an ingress protection rating up to IP67 (dust and water resistant), can operate in -40°C to 85°C environments and can sustain 100g shock and 10g vibration.  

The rugged DAQ devices are built on NI’s flexible and configurable hardware and software platforms. With open and expandable FieldDAQ solutions, test engineers can keep pace with product design cycles and help reduce the overall cost of test, as opposed to the limitations of existing devices with functionality defined by closed, proprietary software.  

FieldDAQ also incorporates Time Sensitive Networking (TSN), the next evolution of the IEEE 802.1 Ethernet standard, providing tight synchronisation over a distributed network of DAQ nodes without additional cabling or complex programming.
