PositionSensor ​

Measures the absolute linear position of a mechanical translational flange.

This sensor provides the absolute translational position of its connection point. It inherits from PartialAbsoluteSensor, which defines a mechanical translational flange. The sensor's RealOutput signal, named s, directly reflects the position variable s associated with this flange. The fundamental behavior is captured by the equation:

s=flange.s

Here, the s on the left side of the equation is the sensor's output signal, and flange.s is the position variable of the connector inherited from PartialAbsoluteSensor.

PartialAbsoluteSensor

Usage ​

PositionSensor()

Connectors ​

  • flange - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)

  • s - This connector represents a real signal as an output from a component (RealOutput)
