weldx.measurement.MeasurementChain#

class weldx.measurement.MeasurementChain(name, source, signal_data=None)#

Class that represents a measurement chain.

Create a new measurement chain.

Parameters:

name (str) – Name of the measurement chain
source (SignalSource) – The source of the measurement chain
signal_data (Optional[TimeSeries]) – Measured data of the sources’ signal

Examples

>>> from weldx import Q_
>>> from weldx.measurement import Error, MeasurementChain, Signal, SignalSource

Create a signal source

>>> current_source = SignalSource(name="Current sensor",
...                               error=Error(Q_(0.1, "percent")),
...                               output_signal=Signal(signal_type="analog",
...                                                    units="V")
...                               )

Create a measurement chain using the source

>>> mc = MeasurementChain(name="Current measurement chain",
...                       source=current_source
...      )
