Up to +400°C / +752°F
Wetted materials for aggressive, corrosive, viscous, solidifying or abrasive media

OPTIBAR DSD 3210

The OPTIBAR DSD 3210 is a two-sided diaphragm seal for mounting to the OPTIBAR DP 7060 differential pressure transmitter. It features a flange design with optional extension for combined direct and capillary tube attachment. The diaphragm seal comes with a wide selection of wetted materials from stainless steel to chemically resistant PTFE or PFA coatings, Hastelloy^®, Duplex, titanium, tantalum and gold. This makes it ideal for absolute or gauge pressure measurement and hydrostatic level applications where it is required to avoid direct contact between the measuring cell of the transmitter and the medium.

Typical applications

Differential pressure measurement or hydrostatic level applications involving:

Very aggressive acids
Corrosive and reducing atmospheres
Viscous and clogging media
Abrasive fluids
High temperature processes up to +400°C / +752°F
