Catalog excerpts

RAILWAY PRESSURETRANSMITTER Swiss based Trafag is a leading international supplier of high quality sensors and monitoring instruments for measurement of pressure and temperature. The pressure transmitter NAR 8258 with increased accuracy of 0.3 % was specifically designed for railway vehicles (EN 50155) and has a long-term stable thin-film-on-steel sensor cell. The wide temperature range from -40°C to +125°C and the triple overpressure protection make the NAR 8258 the ideal choice for railway vehicles in rough environmental conditions. Features ■ measuring accuracy 0.3 % ■ Optional: switching output 1 or 2 PNP transistors ■ excellent long-term stability ■ Dielectrical strength: 710 VDC, meets EN 50155 (Railways) subject to change Data sheet H72307 a 05/2017 Trafag Sensors & Controls Industriestrasse 11 sensors controls
