Tape Sensor & Resolver Plugin (Optional)
The Oxygen Tape Sensor and Resolver Plugin allows speed and angle determination for Tape Sensors (black and white striped band with optical sensor) and for Resolvers with and without envelope detection.
A black and white tape with an optical sensor connected to a CNT input on the DAQ system is required. The gap on the tape needs to be larger than the typical line width of the tape for the gap detection to work properly and detect a single rotation. .
The resolver plugin can be configured in two different modes. Mode 1 is with excitation and mode 2 is without excitation.
Mode 1 requires 3 analog signals:
Sine and cosine must be modulated by the excitation. Envelope detection will happen in software.
Mode 2 requires 2 analog signals:
Sine and cosine must be envelopes and not be amplitude modulated by an excitation signal. Envelope detection must be done by the resolver electronics. No excitation signal is needed and should not be given to the resolver plugin.
Applications include drivetrain power and efficiency testing, where accurate drivetrain speed and angle data is required.
