  Overview

  The OPTIBAR DP 3050 is a differential pressure transmitter with integrated absolute pressure measurement. It is the ideal choice for general flow, level and differential pressure applications. The DP transmitter is currently the most compact pressure transmitter in the market – worldwide. This makes it particularly suitable for space-saving installation in applications with limited space, e.g. in mechanical and technical plant engineering. The compact DP transmitter features the proven-in-use DP transmitter technology of the OPTIBAR series, but comes without the high-end options of the more advanced?OPTIBAR?DP?7060. This way, the OPTIBAR?DP?3050 is also one of the most cost-effective DP pressure transmitters in the market. For DP flow measurements it can be perfectly combined with KROHNE?primary?flow?elements. Equipped with?diaphragm seals, it is the right choice for hydrostatic level and general purpose DP measurements.
