ViFDAQ

ViFDAQ data acquisition system integrates full measurement capability with numerous sensor types (GPS, ADC, digital sensors, accelerations, etc.) and dependable wireless node synchronization in a compact form factor measuring only 50x32x30 mm, including battery for several hours of autonomous operation.

ViFDAQ nodes can join a multi-hop wireless mesh network and sample data simultaneously by preforming a high-precision wireless clock synchronization. Recorded data is automatically merged in a single DAQ-File, eliminating a costly post-processing step when combining data from multiple recording devices.

Features
  • very compact, modular design
  • battery powered
  • multi-hop capable WSN technology
  • dependable, high precision wireless clock synchronization
  • multiple sensor interfaces readily available
  • extendable with new functionality
  • easy integration / application
  • scalable software framework (GUI / API)
Inputs
  • analog signals (fully differential inputs)
  • temperature sensors (thermocouple and RTD)
  • pressure sensors (differential, absolute – down to 25 Pa)
  • RTK GNSS positioning
  • inertial measurement unit
  • CAN-bus interface

ViFDAQ system is easily extended by additional interfaces and sensor technologies.

ViFProbes

ViFProbes are contemporary, simple and robust measuring systems that are very simple and can be used very reliably for the air mass flow measurement on cooling packages.

  • Calculate and store the total air mass flow directly onboard
  • The use of pressure hoses and complex cabling is eliminated
  • The sensors are supplied with energy through one single miniature cable and digitally read out
  • Other confounding factors (such as signal dropouts due to kinked hoses) belong to the past

TOAD – Tomographical optical ammoniak detector

The key parameter for high NOx conversion rates using selective catalytic reduction is the ammonia distribution in the tail pipe. The tomographical ammoniak detector measures the ammonia line concentrations at twenty different light paths. Using sophisticated tomographical algorithm the local ammonia distribution is calculated. The sampling frequency of TOAD is up to 3 kHz, thus highly instationary processes can be studied.
