Because the metal material is used as the elastomer of the load cell load cell, when the fine particles between the external force and the micro-strain disappear, the micro-strain disappears, but whether it can be fully recovered to the original non-stress state will be changed according to the metal data of the elastomer.
If the load force curve does not match the unloading force curve, the larger the difference, the greater the hysteresis. The difference mainly comes from the stability and uniformity of the composition of the data itself, the radial structure after heat treatment, etc. Knowing the causes of hysteresis, we can reduce the hysteresis by selecting the appropriate metal materials and using advanced heat treatment methods to improve the elastic limit. At present, the elastomer widely used in the domestic market is 40CrNiMoA, which can achieve good comprehensive mechanical properties through reasonable heat treatment process.
The strain gauge of the load cell is mainly composed of a sensitive gate, a substrate, a covering layer and a lead. It is the resistance strain effect of the sensitive gate through the sensitive resistance strain effect, if the data itself has a lag, the strain gauge also has a lag. At present, the world's famous strain gauge manufacturers are manufacturing strain gauges with hysteresis fully in mind, and choose self-compensation methods in order to reduce hysteresis to the lowest level. This is also an important factor to consider when selecting a load cell.
After the elastomers and strain gauges are outstanding, the sensor needs to be sealed with sealant, primarily for wire fixing and sealing to prevent the external environment from affecting the sensor's performance. Outwardly, the cured sealant is soft and negligible relative to the strength of the elastomer. This effect is necessary to consider when applying to a small range of forces. When the small force acts as an elastomer, the deformation of the elastomer is small, and the thickness of the sealant affects the deformation.

Single receiver and multiple receiver for photoelectric sensors
Photoelectric sensors are generally composed of three parts: transmitter, receiver and detection circuit, and its operating principle is to first convert the measured change into the change of the optical signal, and then convert the change of the optical signal into the change of the electrical signal (this part is called the "photoelectric effect"). According to the detection method, it is not ...

How to choose an accelerometer
First, understand the digital output part. When purchasing an accelerometer sensor, you must understand the digital output, because this determines the interface between the system and the acceleration sensor, if the number does not correspond, it is inconvenient to use, so you must understand the data at the time of selection.
