NAT 8252 – Industrial Pressure Transmitter

The industrial pressure transmitter NAT 8252 features an exceptionally long-term stable thin-film-on-steel sensor cell with triple (optionally 5-fold) overpressure safety. Optionally, the NAT 8252 is available as a pressure switch with 1 or 2 switching outputs. The robust design and the wide temperature range from -40°C to +125°C qualify the NAT 8252 as the ideal solution for a wide range of demanding applications.

Features

  • Smallest design
  • Completely welded steel sensor system without additional seals
  • Excellent long-term stability
  • Optional: 5-fold overpressure resistance
  • Optional: Switching output 1 or 2 PNP transistors
