The first is the offset error: since the high-frequency pressure sensor maintains a stable straight offset over the entire pressure range, the change in converter diffusion and laser adjustment correction will cause the offset error.
The second is sensitivity error: the magnitude of the error is proportional to the pressure. If the sensitivity of the device is higher than the typical value, the sensitivity error will be an additive function of the pressure. If the sensitivity is lower than the typical value, then the sensitivity error will be a decreasing function of the pressure. The reason for this error is a change in the diffusion process.
The third is the linear error: this is an element that has little effect on the initial error of the high-frequency pressure sensor, which occurs due to the physical nonlinearity of the silicon wafer, but for sensors with amplifiers, the nonlinearity of the amplifier should also be included. Linear error curves can be concave curves or convex curve load cells.
Finally, there is the hysteresis error: in most scenarios, the hysteresis error of the pressure sensor is completely negligible, due to the high mechanical stiffness of the silicon wafer. In general, hysteresis errors only need to be considered in the case of large pressure changes.

Precautions for the use of Autotonics safety light curtains
Cover the safety light curtain with your hands and observe whether the indicator light conversion is normal.
During the use of the punch photoelectric protection device, the orientation of the photoelectric protection device shall not be changed at will.
In the protection zone, the light curtain should be blocked by hand, and the machine should be able to stop the operation immediately.

Introduction to the principle of temperature controller - Autonix
The temperature controller is an electrical switchgear that controls the temperature of an air-conditioned room. The temperature scale in the air-conditioned room controlled by the temperature controller is generally 18°C--28°C. The temperature controller commonly used in window air conditioners uses the principle of pressure effect to promote the opening and closing of contacts. Its structure consists of bellows ...

How to use the Autonex digital fiber optic sensor
Digital fiber optic sensors convert measured objects into measurable optical signal sensors. The principle of operation is to send the incident beam of the light source to the modulator through the optical fiber, and interact with the internal and external measurement parameters of the modulator to form a dimmable signal. Digital fiber optic sensors use ...

Advantages of digital load cells – Autonex
1. The transmission interval of the digital load cell is long, the communication speed is fast, and the anti-cheating effect is remarkable; The output signal of the traditional analog load cell is small, generally millivolt level, and the signal is still lost due to the damage of the cable resistance during the transmission process, and it is also very simple to be affected by the surrounding environment.
