MDM 7210v...
Standard Version
Information on applications, features, metrological infl uences as temperature, level difference, fl oating time and others can be found in model overview 7000. Furthermore there are information on other chemical seal versions.
Construction
The threepart construction (attachment fl ange, upper- and lower part) allows a combination of different materials and a selection of various process connections (male thread or fl ange connections), so that a wide range of application is given. The membrane is welded to the upper part.
Bourdon tube pressure gauges, pressure switches, pressure transmitters, pressure transducers and other pressure measuring instruments can be provided with diaphragm seals of this type series.
Model 7210vG½ has a measuring instrument adapter with female thread for direct mounting to measuring instruments with male thread.
The screwed connections pressure gauge / adapter and the fi lling port must not be loosened respectively opened, as otherwise fi lling fluid leaks and the measuring unit loses its effi ciency.
Model 7210vd8 has an orifi ce d8 for welding to a pressure gauge with process connection d8x5 as instrument connection, e.g.
RCh 100-3vDW, cooling element or capillary line.
Leakage can not occur at the welded connection of pressure gauge / upper part and the fi lling port which ist not accessible externally.
The parts can be cleaned externally.
