The pressure sensors produced by Tianguang company can be divided into resistance strain type and diffused silicon type. According to the structure, each type is divided into two types: with a cavity and without a cavity. The cavity has high accuracy and a wide range; the cavityless is easy to clean and is suitable for liquid pressure measurement with impurities. Pressure force sensors are usually used in chemical, metallurgical, aerospace, and other industries.
A sensor is a kind of detection device, the function of pressure sensors is mainly that feeling the information being measured and transforming the sensed information into electrical signals or other required forms of information output according to a certain rule, so as to satisfy the transmission, processing, storage, and display of information, recording and control requirements. Sensitivity is an important indicator of sensor performance indicators, which refers to the ratio of sensor output increment to input increment. For the load cell, it is the ratio of the output voltage signal of the sensor to the force load. For the load cell, we hope that there is a linear relationship between its output and input. At this time, the load cell sensitivity S is a constant. Here is a datasheet of the pressure sensor for your reference, the range of the sensor is 200N and the sensitivity is 2.0mV/V, then when the sensor is subjected to a force of 100N, the theoretical output voltage is 10mV when the power supply is 10V. Similarly, when the sensor outputs 20mV, the force should be 200N.
