OPTIBAR DSD 3220 Diaphragm seal

The OPTIBAR  DSP 3220 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 2 x 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 direct contact between 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
