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. The new NAR 8258 pressure transmitter/switch is the successor of the well-proven NAH 8253 with railway option. In addition, the NAR 8258 includes a pressure switch option. Based on the robust, reliable and successfully introduced NAH 8254 the NAR…

Concerns ECT 8471 / 8472 / 8473 Ceramic pressure transmitter The tool for crimping the electrical connectors Packard Metri Pack, M12x1 and Industrial Standard for the new production line was optimized to improve the quality and reliability of our instruments. All instruments manufactured with the new tool can be identified by six crimping marks on the housing. All specifications and properties remain unchanged. DThe robustness of the new design is slightly higher, particularly under elevated temperatures. The major difference is the visual appearance due to the different manufacturing tool. The major difference is the visual appearance due to the different manufacturing tool. The change affects the types 8471, 8472, 8473, 8474, 8475 and 8477 with…

The electronics complies with EMC standards EN/IEC 61000-6 and features an integrated lightning protection as…

Due to its excellent price performance ratio and outstanding chemical resistance the new Submersible Transmitter ECL 8438 is suitable for a wide range of applications where reliable measurement of a fluid level is required over a considerable period of time. Measuring ranges from 0 to 0.1 through to 0 to 25 bar are available. The amplifier electronics which incorporate Trafag’s in-house developed ASIC offer the best available technology and allows for the compensation of temperature-driven drift effects. The NLH accuracy of the Trafag ECL submersible transmitter is +/-0.2%. Alternatively the Trafag NAL submersible transmitter is available with +/-0.1% NLH accuracy.The sensor’s slim body is made of stainless steel and can easily be inserted…

The new miniature pressure transmitter NAE 8256 is a unique solution on the basis of HEX19 combined with ship approvals offering an accuracy of up to ±0.3 % and extraordinary robustness and reliability. Bubikon, September 2015 – The heart of the new pressure transmitter NAE 8256 is Trafag’s very robust and extraordinary stable thin-film-on-steel sensing element which remains accurate and reliable even under rough conditions due to the triple overpressure safety and the fully welded design. The electronics are based on the inhouse designed ASIC, an application specific microchip which achieves optimal temperature compensation and linearization of the measurement over the wide operating temperature range of -40 … 125°C. The combination of the HEX19…
