Ex pressure transmitter for demanding industrial applications

Trafag‘s intrinsically safe EXNT 8292 Ex Pressure Transmitter is designed to deliver reliability and safety in the toughest industrial environments. Certified and engineered for optimal performance, the EXNT 8292 addresses the demands of hazardous locations, hydrogen infrastructure, marine sectors, and beyond.

Certified for use in Ex Zones 0, 1, and 2 (gas), 20, 21, and 22 (dust), as well as mining environments, the EXNT 8292 enables safe operation and ensures compliance with international safety regulations. ATEX, IECEx, and UKEX certifications make this transmitter suitable for global applications where adherence to stringent explosion protection standards is paramount. For hydrogen applications, the EXNT 8292 is EC79/2009 certified by KBA (Kraftfahrt-Bundesamt), supporting secure and approved deployment in emerging hydrogen infrastructure. The optional hydrogen-compatible sensor guarantees reliable, long-term pressure measurement even in demanding hydrogen environments. The EXNT 8292 is also approved for use in shipbuilding and marine applications with DNV, KRS, and RMRS marine certifications, guaranteeing device reliability and regulatory acceptance in these critical sectors.

The EXNT 8292 offers exceptional versatility across multiple industries and varied pressure measurement tasks. Its excellent overpressure resistance helps protect against process pressure spikes, significantly enhancing uptime and safety. A wide operating temperature range from –40°C to +120°C makes the EXNT 8292 suitable for harsh industrial, outdoor, and mobile environments. The robust, all-stainless-steel wetted parts increase corrosion resistance, longevity, and reliability even when handling aggressive media.

At the core of the EXNT 8292 is Trafag’s advanced thin-film-on-steel sensor technology, ensuring excellent long-term stability and precise reliability throughout the product’s lifecycle. The transmitter delivers highly accurate measurements, with typical values of ±0.3% or ±0.5% FS at 25°C, supporting process control and reducing the risk of measurement errors.  Rated at IP65/IP67, the transmitter resists dust and water ingress to perform reliably in challenging environments.

To simplify integration, the device offers multiple electrical connections, including EN175301-803-A, M12x1, MIL-C 26482, Binder 723, and cable options, ensuring compatibility with a variety of systems and installations. With its compact, low-weight design, installation is easy even where mounting space is limited. Its standard output signal of 4-20 mA further supports seamless industrial process control and system compatibility.

Designed for ruggedness, the EXNT 8292 delivers high vibration (10g) and shock (50g) resistance and strong EMC immunity, maintaining reliable operation in harsh industrial conditions. Customization options, such as various sensor materials, pressure ports, and accessories (peak damping elements, special seals), allow for precise tailoring to the requirements of specific media and installation setups.
