Pressure Transmitter
This line of pressure transmitter has strong anti-overload performance and impact resistance. Its overload capacity is multiple times of its measuring range. Even direct knocking on measuring elements cannot damage the pressure transducer, and won't cause bad influence on measuring accuracy.
The pressure transmitter has high stability. The full scale error is less than 0.1% every year, which is comparable with that of smart pressure measuring devices.
Low temperature drift. The measuring elements eliminate the demand for filling fluid. Thus, the pressure sensor can acquire very high measuring accuracy which cannot be affected by the temperature gradient.
The pressure transmitter has a wide range of applications, and features convenient installation and maintenance. It supports any-position installation.
