Description
The separation vessel is designed to protect the sensitive element of a measuring instrument (pressure gauge, pressure transmitter, pressure relay, etc.) from exposure to a wide range of aggressive, highly viscous, and contaminated operating media.
Due to the absence of diffusion through the metal diaphragm, it can be recommended for pressure measurement of both liquid and gaseous aggressive media.
Applications
-
Contaminated media
-
Highly viscous media
-
Solidifying media
-
Liquid aggressive media
-
Gaseous aggressive media
Design: Detachable, with external/internal diaphragm placement.
Process connection: Flanged, according to GOST, DIN, or ANSI standards.
Features: Filling only with vacuum equipment; well suited for highly viscous and contaminated operating media.
Operating pressure range, kgf/cm²: –1…250
Additional information: Reference codebook for Separation Vessel Type WD.
