NAI 8273 IO-Link Pressure Transmitter and Switch

Main features

  • Pressure measuring accuracy 0.3 %, 0.5 %
  • Media and device temperature measurement
  • COM3, min. process cycle time 1 ms
  • 2 Switching outputs PNP/NPN configurable
  • Optional: 5-fold overpressure resistance


The NAI 8273 IO-Link pressure transmitter is designed as a smart sensor and provides application-relevant information in addition to the process data. The process data contains the pressure value and the media temperature, which is measured directly at the exceptionally long-term stable thin-film-on-steel pressure sensor cell. The small sensor dimension combined with the pressure and temperature value of the media make the NAI 8273 the ideal choice in various applications. For the use of the conventional switching outputs, the polarity NPN and PNP is configurable.
