The root cause of mechanical deformation inside the pressure transmitter
The root cause of the internal mechanical deformation of the pressure transmitter For domestic pressure transmitters, we always follow the steps of others. In pursuit, this is the biggest problem in the field of transmitter technology. If we say that in these pressure transmitter instruments, because of the open bus, the technology gap is relatively small, then in the field of desktop instruments, the gap between domestic and foreign is almost impossible to estimate. When the domestic pressure transmitter is used, mechanical deformation may occur.
The tiny changes in the distance between the sensitive sensor's internal plate of the pressure transmitter can produce measurable voltage signal changes. The small mechanical deformation greatly reduces the hysteresis and non-repeatability of the sensor, and the speed of the sensor is also very high. improve. The pressure transmitter has a wide measuring range, it can accurately measure the pressure in the range of 25Pa ~ 70MPa, and has a very high stability. The minimum measuring range of the sensor of the high-precision differential pressure transmitter is 0-125Pa, the measurement accuracy can reach 0.073%FS, and the static pressure can be from vacuum to 1.7MPa. In the range of 0-65°C, the temperature effect is <±1.8% FS/100°C, and the overload capacity is up to 270 times that of FS.
Internally produced pressure transmitters sometimes exhibit internal mechanical deformation. This is something we should notice when working with the transmitter. This phenomenon is difficult to avoid when using the transmitter. However, we can reduce this phenomenon through usual daily maintenance.
