OPTIBAR DP 3050

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.

KROHNE is the only manufacturer of process instrumentation to carry out a total 3D linearization of its differential pressure transmitters. For a robust and accurate differential pressure measurement, even under changing process conditions, each OPTIBAR DP 3050 differential pressure transmitter is linearized in all three dimensions during calibration: differential pressure, ambient temperature and static pressure are taken into account in combination. Since the full specified operating range is covered, an utmost stable and accurate measurement under all process conditions is guaranteed.
