introduction：Load cellIt is actually a device that converts a mass signal into a measurable electrical output。The use of sensors should first consider the actual working environment in which the sensor is located，This is crucial to the correct selection of load cells，It is related to whether the sensor can work properly and its safety and service life，And even the reliability and safety of the whole weighing apparatus。The basic concept and evaluation method of main technical index of load cell are discussed，There are qualitative differences between the old and the new countries。There are mainlyStype、Cantilever type、Spoke type、Plate-ring type、bellows、Bridge type、Cylinder-type and other styles。 Major advantage： resistance、Inductors and capacitors are three kinds of passive components in electronic technology，Capacitive sensors are sensors that convert the measured change into a change in capacitance，It is essentially a capacitor with variable parameters。
