EX SUBMERSIBLE PRESSURE TRANSMITTER EXNAL 8858

Product catalog summary

Overview: The document provides detailed technical specifications for the EX Submersible Pressure Transmitter by Trafag, a Swiss-based company known for high-quality sensors and monitoring instruments. This transmitter is designed for use in shipbuilding and explosive environments, with various pressure ranges and materials available.

Applications: Suitable for pressure ranges starting from 100 mbar, the transmitter is made from chemical-resistant materials like titanium and offers explosion-proof capabilities (Ex ia IIC T3 ... T6). An optional feature includes lightning protection compliant with IEC 61000-4-5 standards.

Technical Data: The transmitter operates on a piezoresistive measuring principle with an output signal of 4 ... 20 mA. It is approved for use under GL and KRS standards and offers a media and ambient temperature range of -5°C to +50°C. The device is protected under IP68 standards and can withstand vibrations up to 6 g and shocks up to 50 g.

Ordering Information: The product code 8858 includes various configurations for measuring range, sensor type, pressure connection, electrical connection, and output signal. Custom pressure ranges and additional features like special oil filling and titanium construction are available upon request.

Specifications: The transmitter offers repeatability of ±0.05% FS and a rise time of approximately 1 ms. It is designed to handle environmental conditions with a maximum humidity of 95% and complies with EMC protection standards. Mechanical components are made from AISI316L or titanium, with a sealing of FKM (Viton).

Accuracy: The accuracy varies by pressure range, with NLH accuracy of ±0.1% FS for higher ranges. Temperature coefficients for zero point and span are provided, along with long-term drift specifications.

Dimensions: The document includes dimensions for standard and lightning-protected models, with specific cable diameters for PUR and FEP cables.
