FDK083N8291

Product Description

It is a combined grounding and protection ring of type E, sized DN 80 (3 inch) for ANSI B16.5 Class 150 installations, manufactured in stainless steel AISI 316 (material 1.4436) and intended for sensors with PTFE liners. Supplied as 1 piece, the ring provides reliable electrical grounding of the measured liquid and protects the liner edge against abrasion and damage at the flange joint. Using the correct grounding ring is essential for the accuracy and long service life of an electromagnetic flowmeter, and this original Siemens part guarantees full dimensional compatibility with the MAG 3100 DN 80 sensor. The Siemens FDK:083N8291 is a genuine SITRANS F M accessory for the MAG 3100 electromagnetic flow sensor series.

Basic Product Information

• DN 80 (3 inch) size for ANSI B16.5 Class 150 installations
• Stainless steel AISI 316 (1.4436) for corrosion resistance in aggressive media
• Designed for sensors with PTFE liners, protects liner edge and ensures correct liquid grounding

Technical Specifications

Version & Model Difference

Within the MAG 3100 accessory range, grounding rings are offered as flat rings (for all liners) and as grounding and protection rings type E (for PTFE liners). The FDK:083N8291 is the DN 80 ANSI Class 150 type E version in AISI 316 stainless steel; other sizes and pressure ratings use different FDK:083Nxxxx order numbers.

Application Scenarios

• Grounding of conductive liquids in electromagnetic flow measurement on DN 80 lines
• Protection of PTFE liner edges on MAG 3100 sensors in abrasive or corrosive service
• Retrofit and spare part for existing SITRANS F M installations
• This article is supplied as 1 piece. Depending on the installation, grounding rings are typically fitted on one or both sides of the sensor; please confirm your installation requirement when ordering.
