CTS330 is an atmospheric pressure gauge using silicon resonant MEMS pressure sensor as the core, combined with advanced microprocessor-based processing circuitry and temperature and pressure compensation algorithms, it can achieve better than ±10Pa testing accuracy within the range of 70~115KPa, and real-time collection and display of atmospheric pressure data, and can be used to realize the remote acquisition and detection of collected data through RS-232 or Ethernet interface. The data can be collected and displayed in real time.
