In the selection pressure sensor when we have to consider his overall accuracy and precision of the pressure sensor by the impact of what? In fact, cause there are many factors that sensor error, the following note to say we can not avoid the error of four, which is the sensor initial error. First offset errors: Due to the pressure sensor over the entire pressure range of the vertical offset is kept constant, and therefore the converter and the diffusion of laser adjuster correcting the changes will have an offset error. Followed sensitivity error: error magnitude proportional to the pressure to produce. If the sensitivity of the device is higher than the typical value of the pressure sensor price, sensitivity error will be an increasing function of pressure. If the sensitivity is lower than the typical value, sensitivity error will be a decreasing function of pressure. The cause of this error is that the change in the diffusion process. The third is the linearity error: This is the initial pressure sensor smaller error influence factor, the cause of the error in that the non-linear physical silicon pressure sensor, but with respect to the sensor amplifier, should also include non-linear amplifier. Linearity error curve may be concave curves, convex curves can also be load cells. Finally, the hysteresis error: In most cases, the hysteresis error of the pressure sensor is completely negligible, because silicon has a high mechanical stiffness. Generally only consider the hysteresis error in pressure situations vary greatly. The four pressure sensor error is inevitable, we can only choose high-precision production equipment, using high technology to reduce these errors can also be a bit of an error when the factory calibration, to the greatest extent possible in order to reduce errors meet customer needs, if forced to install the sensor in the hole is too small or irregularly shaped holes, it may cause shock and impact sensor membrane damage, choose the right tool for machining mounting hole pressure sensor applications, help control the installation hole size pressure sensor manufacturers, in addition, proper installation torque is conducive to the formation of a good seal, but if the installation torque is too high, it is easy to cause slippage melt pressure sensors, in order to prevent this from happening, usually before the sensor is installed in Apply anti-off compound on its threaded portion.
