Helium test - Import export

The pressure transmitter DMP 331 can be used in all industrial areas when the medium is compatible with stainless steel 1.4404 (316 L) or 1.4435 (316 L). Additional are different elastomer seals as well as a helium tested welded version available. The modulare concept of the device allows to combine different stainless steel sensors and electronic modules with a variety of electrical and mechanical versions.Thus a diversity of variations is created, meeting almost all requirements in industrial applications. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 60 bar — accuracy: 0.35 % (opt. 0.25 % / 0,1%) FSO — excellent thermal behavior — excellent accuracy — flush pressure port G 1/2" from 100 mbar Optional Features: — IS-version Ex ia = intrinsically safe for gases and dusts — SIL 2 according to IEC 61508 / IEC 61511 — pressure sensor welded — customer specific versions

Pre-compressed ring-set made of expanded graphite and reinforcement to protect against extrusion Characteristics Packingset made by combining two expanded Graphite grades and designs in order to avoid blow out and extrusion and as well enhance the sealability of this valve sealing set. The set was tested and approved by the AMTEC GmbH Lauffen in Germany. The leakage parameters of 8.6 x 10-3 mbar · l/(s·m) complies with the VDI 2440 at +400 °C, which specifies a maximum allowed leakage of 1.0 x 10 -2 mbar · l/(s·m) (test media helium) and is therefore recommended as a high grade seal system. Operating range Pressure without LiveLoading: p 40 [bar] Pressure with LiveLoading: p 160 [bar] Temperature without LiveLoading: t 400 °C Temperature with LiveLoading: t 400 °C pH: 0 - 14 Main application Valves Flaps Gate valves Fittings Suitable for Power plant technology Chemical industry Petrochemical plants Boiler houses Refineries Approvals TA Luft / VDI 2440 Certificate
