The CANdaq
is a self contained single scanner acquisition system. It can
acquire data from a PSI
pressure scanner , The Chell I-Daq analogue
scanner and the Chell T-Daq temperature
scanner.
Pressure Scanners
The CANdaq takes full advantage of the DTC
pressure scanner technology and makes interfacing with them straightforward.
The DTC pressure scanners contain all their coefficients in an EEPROM inside
the scanner. They also compensate for temperature by measuring the temperature
of every transducer. The DTC scanners also contain a 3X deranging option and
shuttle valve position sense and all these functions can be accessed by the
supplied software.
With standard scanners, temperature compensation is also available through
the single temperature output offered by the scanners.
The CANdaq can also be used with the QD-VP
valve driver which gives software control over the pressure scanner
shuttle valve.
Voltage, Current and Temperature
Scanners
The CANdaq will acquire voltages and currents from the Chell
I-Daq and temperatures from the Chell T-Daq. |
The CANdaq
senses what scanner type is
connected to, either a DTC scanner, a conventional scanner, an I-Daq or a T-Daq.
The appropriate calibration coefficient and algorithms are then employed. This
enables DTC scanners, I-Daqs and T-Daqs to become ‘ plug and play’.
Hardware Trigger
The CANdaq also has the option of a hardware trigger. This can be used to
provide time deterministic data.
The CANdaq will operate at high accuracy and unparalleled
high speed making it suitable for a variety of applications.
These range from wind tunnels, to education and on-car race applications.
Software
The software supplied with the CANdaq allows the user to configure the acquisition
in terms of speed, averaging and thermal compensation method used. It also
provides a calibration interface, real time data window and data logging facilities.
The CANdaq is supplied with a DDE interface so data can be directly acquired
into third party software such as Excel.
Easy to use wizards are also available to help
configure the CANdaq to the application.
