Applications ■ machine tools ■ Hydraulics ■ HVAC ■ Refrigeration ■ Process technology ■ Water treatment INDUSTRIAL PRESSURETRANSMITTER Swiss based Trafag is a leading international supplier of high quality sensors and monitoring instruments for measurement of pressure and temperature. 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. ■ Smallest design ■ Completely welded steel sensor system without additional seals ■ excellent long-term stability ■ Optional: fivefold overpressure resistance ■ Optional: Switching output 1 or 2 PNP transistors Subject to change data sheet H72303n 04/2017 Trafag Sensors & Controls Industriestrasse 11 sensors controls
