A force-sensitive resistor (FSR) is a material which changes its resistance when a force or pressure is applied. The conductive film is an example of such force resistance material. In other words, the force-sensitive resistor is a sensor that allows you to detect physical pressure, squeezing and weight.
The principle of the pressure sensor test is to apply the stress applied in the sensing area of the sensor film into the change of the two-line resistance value and obtain the external stress change information according to the calibration curve of the stress-resistance.
The greater the stress, the lower the sensor output resistance. The RFP film pressure sensor can measure the pressure of any contact surface statically and dynamically.
For test soil pressure measurement, test material pressure distribution measurement (not recommend to use in fields which need to teat precise pressure).
