The process pressure is transmitted hydrostatically to the measurement cell via the pressure transfer fluid.   This device is used for applications in which a standard pressure connection could become blocked, clogged or frozen by the particular medium used.   Further applications include processes where the medium changes regularly and any residues could cause mixing or contamination of the media, or in highly viscous media. Intended areas of application are, for example, the oil and gas industry, in mines or in locations with high levels of dust, e.g. in mills.
