The Advantages And Disadvantages Of Resistive Sensors Advantages
Sep 29, 2018

(1) large non-linearity and weak output signal, but certain compensation measures can be taken. Therefore, it is widely used in automatic test and control technology.


(2) the resistance strain gauge in the resistance strain sensor has a metal strain effect, that is, mechanical deformation is generated under the action of external forces, so that the resistance value changes accordingly


disadvantages


(1) large non-linearity for large strain, but weak output signal.


(2) the material and device performance of the sensor will change with the change of time and environment. Therefore, it is not suitable for long-term monitoring because time drift and temperature drift are relatively large. Therefore, real and effective data may not be obtained by long-term measurement.


(3) easy to be affected by electric field, magnetic field, vibration, radiation, air pressure, sound pressure, airflow, etc
