MD

Overview

The MD series of Gefran, are pressure transmitters for using in High temperature environment and specifically designed for melt pressure measurement and available only to be used in large-scale fixed installations or in large-scale stationary industrial tools, typically extruders, or for laboratory B2B equipments for R&D purposes according to the European Directive 2011/65/EU (see informative note RoHS II).
