Abstract

The invention discloses a calibration device for an FSR pressure sensor. The device comprises a pedestal; a stepping motor sliding table assembly which comprises a stepping motor, a stepping motor supporting seat, a shaft coupler, a sliding table assembly support, a ball nut sliding table, a screw, and a sliding table assembly lower supporting plate, wherein the sliding table assembly support is vertically disposed on the pedestal, the screw is in drive connection with the stepping motor through the shaft coupler, and the ball nut sliding table is disposed on the screw in a manner of moving up and down; an overload protection force-applying probe assembly which comprises a sleeve, a force-applying head, and a telescoping rod, wherein the sleeve is fixed on the ball nut sliding table, the force-applying head is disposed below the sleeve through the telescoping rod, and the stepping motor drives the screw to rotate so as to drive the ball nut sliding table to move downwards; a pressure sensor and an objective table. The device is smaller in size, is convenient for assembly and debugging, and is high in calibration precision and efficiency.

Description

technical field [0001] The invention relates to the field of sensor calibration devices, in particular to a calibration device for FSR pressure sensors. Background technique [0002] The FSR pressure sensor is a very convenient pressure sensor. Because the FSR sensor has certain flexibility, it can be attached to various surfaces that are often deformed. FSR pressure sensors are widely used in the fields of biomedical engineering, robotics, and rehabilitation medical equipment. The main material of the FSR sensor is a force-sensitive polymer. The principle of FSR measuring force is: the axial force applied to the FSR will change the resistance of the FSR, and the change of the resistance of the FSR will be reflected to the change of the voltage through the voltage divider circuit. superior. The calibration of the FSR sensor requires the use of the calibration device of the FSR pressure sensor to find out the relationship between the applied pressure and the output voltage ...
