Product catalog summary

Overview: The document is a technical datasheet for the Trafag Submersible Pressure Transmitter, model EXNAL 8859, designed for use in hazardous environments such as gas and dust zones, and underground mining. It highlights the transmitter's applications, features, technical specifications, and ordering information.

Applications: The transmitter is suitable for ATEX and IECEx environments, with pressure ranges starting from 100 mbar. It is designed without media-contacting O-rings and offers options for chemical-resistant materials like titanium.

Features: Trafag is a Swiss-based company known for high-quality sensors. The transmitter operates on a piezoresistive measuring principle, with an ambient and media temperature range of -5°C to +80°C. It complies with IEC/EN 60079 standards for explosive atmospheres.

Technical Data: The transmitter provides a 4-20 mA output signal and is protected under various explosion-proof classifications. It offers a wide range of pressure measurements from 0.1 to 25 bar, with specific overpressure and burst pressure ratings. The device is available in both relative and absolute pressure types, with accuracy levels of ±0.1% to ±0.25% FS.

Ordering Information: The type code includes options for pressure range, sensor type, pressure connection, electrical connection, and output signal. Additional options include detachable cables, special oil fillings, and temperature classes.

Specifications: The transmitter has a repeatability of ±0.05% FS and operates with a supply voltage of 9-28 VDC. It is designed to withstand environmental conditions such as vibration, shock, and electromagnetic interference, with protection ratings up to IP68.

Mechanical Data: The sensor and housing are made from AISI316L stainless steel or titanium, with sealing options of FKM, EPDM, or Kalrez. The device weighs approximately 220 grams and requires a mounting torque of 25 Nm.

Accuracy: The document provides detailed accuracy specifications across different pressure ranges and temperature conditions, with long-term drift specified as less than 4 mbar or 0.2% per year.

Additional Information: Links to further documentation, including data sheets, instructions, and flyers, are provided for more detailed information.

Dimensions: The document includes dimensions for standard and lightning-protected models, with specific measurements for electrical connections and Zener barriers.
