Applications ■ machine tools ■ Hydraulics ■ hvac ■ Refrigeration ■ Process technology ■ Water treatment HYDRAULIC PRESSURE TRANSMITTER Swiss based Trafag is a leading international supplier of high quality sensors and monitoring instruments for measurement of pressure and temperature. The hydraulic pressure transmitter NAH 8254 with increased accuracy of 0.3% and optional switching outputs has an exceptionally long-term stable thin-film-on-steel sensor cell with triple (optionally 5-fold) overpressure protection. The robust design and the wide temperature range of -40°c to +125°c make the NAH 8254 the ideal solution when pressure needs to be measured accurately and reliably under rough environmental conditions. ■ measuring accuracy 0.3 % ■ 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 H72304g 04/2017 Trafag Sensors & Controls Industriestrasse 11 trcifciqsensors controls
