GeneralThe VectoDAQ Air is designed to measure multiple
pressure signals and temperature simultaneously.
The device also performs data reduction, allowing
you to monitor and record engineering data in realtime. The setup can be used with any laptop, in fieldor laboratory environment.

The CAN-bus protocol is implemented according tothe CAN 2.0A or CAN 2.0B specification with Baudrates up to 1 Megabaud. A DBC-file (Vector-format)
is supplied for easy integration in measurement
environments. CAN/Power connector cables can besupplied, including a CAN termination resistor.
Power is supplied over the CAN bus connector(Lemo connector). The grounding of the device isgenerally recommended.

The data acquisition can be done with VectoVis,
where e.g., a live view of all data and data recording
function in readable file formats such as .csv isavailable.

The data can be transmitted either by USB or CAN
protocol. The transmission rate can be set up to 50Hz.
When connected via USB the pressure scanneridentifies itself to the host PC as a virtual COM port.
Thus, any software supporting serial protocols canbe used for communication. A 5 V power supply isprovided simply via USB.

The VectoDAQ Air is equipped with up to 14
differential and one absolute pressure channel. All
differential pressure sensors can be selected bypressure range. The temperature-compensatedpressure transducers feature high accuracy and aminimal offset drift. The high proof pressure provides
sufficient protection against accidental overloads.
