Ideal Force Sensor
Force sensor in mechanical translational systems
Simscape / Foundation Library / Mechanical / Mechanical Sensors
The Ideal Force Sensor block represents a device that converts a variable passing through the sensor into a control signal proportional to the force. The sensor is ideal since it does not account for inertia, friction, delays, energy consumption, and so on.
Connections R and C are mechanical translational conserving ports. Connect this sensor in series with the block where you want to measure the force because force is a Through variable (for the mechanical translational domain). The sensor constrains ports R and C to allow no motion between them, therefore connecting the sensor in parallel may affect the simulation results because it is analogous to adding a bypass connection line between the connection points. A series connection within an existing line does not affect the simulation results and provides an accurate measurement.
Connection F is a physical signal port that outputs the measurement result. The block positive direction is from port R to port C. This means that positive force applied to port R (the sensor positive probe) generates a positive output signal.
F — Force, N
Physical signal output port for force.
R — Rod (positive probe)
Mechanical translational conserving port associated with the sensor positive probe.
C — Case (reference probe)
Mechanical translational conserving port associated with the sensor negative (reference) probe.
