The OPTIBAR DP 3050 is currently the worldwide most compact pressure transmitter on the market. It offers precise differential pressure measurements for flow and level application with integrated line pressure measurement and advanced total 3D linearisation.
For DP flow measurements it can be perfectly combined with the KROHNE primary elements (e.g. orifice plates or pitot tubes). Featuring a quick response time of just 125 ms, the DP transmitter offers high accuracy and measurement stability under all process conditions.
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.
Highlights:
Fully welded stainless steel construction
The fully welded stainless steel construction provides utmost robustness and sturdiness which are as important as accurate and precise measurement.
Total 3D linearization
For a robust and accurate differential pressure measurement, even under changing process conditions, each OPTIBAR DP 3050 differential pressure transmitter is linearized in 3 dimensions during calibration.
The following values are taken into account in combination (as example):
- Differential pressure from -500 to +500 mbar,
- Ambient temperature from -40 to +85°C,
- Static pressure from 0 to 160 bar.
Since the full specified operating range is covered, an utmost stable and accurate measurement under all process conditions is guaranteed.
Integrated absolute pressure measurement
The OPTIBAR DP 3050 uses besides the differential pressure sensor an absolute pressure sensor with PN400 rating up to 5800 psi. The sensor offers unprecedented robustness for ever changing process conditions as well as a secondary process variable for monitoring functions.
High accuracy and temperature stability
The full digital linearization and temperature compensation provides an accurate measurement signal under changing temperature conditions.
