TimeToLength

TimeToLength('Expression','Speed','Precision')

Arguments

'Expression'

Signal or expression to convert to length

'Speed'

Speed signal

'Precision'

Optional parameter to determine the sampling rate of the resulting signal in m

Description

This function converts the time based signal 'Expression' into a length based signal, with the speed of the measuring object 'Speed' serving as the speed vector in m/s.

This function can convert any signal for which a matching speed signal is available into a length based presentation. This means that it is possible to present not just the relationship between measured value and time but also between measured value and distance traveled.

Taking the example of a steel strip in a rolling mill, this function can determine the distribution of measured values over the strip length. If the process was designed in such a manner that the beginning and end of measurement are in exact conformity with the head and tail ends of the strip, this function can then calculate the total strip length. The largest length value determined is entered as the scale end value of the X-axis (autoscale).

'Precision' is an optional parameter in m. If no precision value is defined, the points for the length based curve are calculated and entered in the graph on the basis of the number of measuring points of the original signal. If a precision value is defined, for example, 0.1, a new length-related value is calculated and entered as a point of the curve every 0.1 m.

The following illustration shows time-length function TimeToLength.

TimeToLengthL

TimeToLengthL('Expression','Length','Precision')

Arguments

'Expression'

Signal or expression to convert to length

'Length'

Length signal

'Precision'

Optional parameter to determine the sampling rate of the resulting signal in m

Description

This function converts the time based signal 'Expression' into a length based signal, with a length signal 'Length' as the position in m.

The explanations given under TimeToLength apply accordingly, however, with the only difference that a suitable length or position signal is used instead of the speed.
