Force/moment sensors: essential for fine perception

A force/moment sensor is a sensor that can sense force and moment and convert it into an available output signal. It mainly includes two parts: the body unit and the strain/deformation detection system. The core NOTIFIER ACPS-2406
principle of the force/moment sensor is to convert the deformation of the force into an electrical signal. When the force/moment acts, the force/moment is applied to the element of the sensor body, and causes the strain or deformation of the body unit. The detection system can sense the strain or deformation of the body, and convert it into the corresponding voltage through the circuit. The force/moment size is characterized by measuring the voltage value, and is converted into the output signal to achieve the measurement of the force/moment.

According to the measurement principle, the force/moment sensor can be divided into photoelectric, strain, capacitance, piezoelectric and other types. Among them, the strain gauge force/moment sensor is the most mature and widely used sensor type at present, which has the advantages of simple structure, easy production and low price.

According to the measurement dimension, the force/moment sensor can be divided into one to six dimensional force/moment sensors. The general sensor can measure several dimensions, that is, several dimensions sensor. One-dimensional, three – and six-dimensional force/moment sensors are the most common. For the six-dimensional force/moment sensor, the force F in any direction in space, its application point P does not coincide with the sensor’s calibration reference point and changes randomly. In this case, the six-dimensional force/moment sensor should be selected to complete the measurement task and measure the NOTIFIER ACPS-2406
six components Fx, Fy, Fz, Mx, My and Mz at the same time. The internal algorithm of the six-dimensional force/moment sensor will decouple the interference between the forces and moments in all directions, making the force measurement more accurate. This kind of sensor is more suitable for the reference point distance is far, and the situation of random change, the measurement accuracy is higher.
