The load sensor is the sensor device that is measured by the load that is subject to the force carrier to complete the amount of measurement to the object.The heavy sensor can convert the pressure from the carrier to the corresponding electrical signal to achieve the purpose of measurement.
Loch sensor repair
When checking the load sensor of the electronic device scales, first check the appearance of the symmetrical weight sensor, and then gradually test it.On the basis of understanding its working principles, if you carefully observe, analyze, and test it carefully, the fault will be quickly excluded.
Loch sensor wiring
The load -heavy sensor can adopt two different input and output wiring methods: one is the four -line connection method, and the weighing sensor of the four -line connection method has no special requirements for the second instrument.For a long time, it is easily affected by factors such as environmental temperature fluctuations; the other is the six -line connection method (as shown in Figure 1). The load -heavy sensor of the six -line connection method requires the secondary instrument used to use feedback inputThe interface has certain limitations, but it is not easy to be affected by factors such as environmental temperature fluctuations. It has certain advantages in precision measurement and long -distance measurement.
Principles of Lotus Sensor
The principle of elasticity of the load sensor elastomer is a structural part with a special shape.It has two functions. First, it is affected by the external forces suffered by the weighing sensor, and the external forces have reaction forces to achieve a relatively quiet balance.The resistance strain film is ideal to complete the conversion task of the adaptation date.Taking the elastic body of the SB series load sensor of the Torio company as an example to introduce the stress distribution in it.There is a rectangular cantilever beam with a holes.The center of the bottom of the cavity is to withstand pure shear stress, but stretching and compressing stress will occur in the upper and lower parts.The main stress direction is to pull the gods and the first is compression. If the strain film is attached here, the upper half of the film should be stretched and the resistance value is increased. Instead, the lower half of the film will be compressed and the resistance value will be reduced.
