Software options


Many applications require more than one measurement device, sometimes even at different locations. OXYGEN-NET makes it possible, to sum up all devices to one virtual measurement device. You only need a reliable network connection, then you can simply claim all available nodes and operate them from the main device.

  • Create one big virtual device with several remote measurement nodes
  • Simply claim and remove nodes with one click (no complicated settings needed)
  • Work with absolute time synchronization as well as with TRION-SYNC-BUS
  • Store your data locally and remotely to benefit from redundancies

You need the acquired data to be available on the CAN-Bus? No problem, the optional CAN-transmit function makes it very easy to serve almost every OXYGEN channel cyclically on the CAN-bus.

  • Send and receive simultaneously on the same bus
  • Simply drag’n’drop the channels to the CAN-signal
  • Select the transmission interval individually for each CAN-message
  • Optionally tune the transmission delay to choose between quality or responsiveness
Ethernet Receiver

You have data sources you want to use in OXYGEN? The Ethernet receiver is your solution. It supports the decoding of UDP-packets into OXYGEN channels so you can visualize and record them together with all your other data. On the other hand, data can be output via UDP-streams for monitoring on different instances.

  • Support of 1 to several receiver and sender instances
  • Simple XML decoding structure for packet description
  • Optional time synchronization with timestamp decoding
Sound Level Option

Provides online determination of the time-dependent sound pressure level, the energy equivalent sound pressure level, freely definable statistical sound pressure levels, and many more.

  • A-, B-, C-, D- and Z-frequency weighting (according to DIN EN 61672-1)
  • Fast, slow, and impulse time weighting (according to IEC 651)
  • Reference level for air (20 µPa) and water (1 µPa)
  • Overall and interval logging
