The OPTIBAR DP 7060 is a differential pressure transmitter with integrated absolute pressure measurement. It offers a high degree of modularity for various flow, hydrostatic level or process pressure applications. For DP flow measurements it can be perfectly combined with the KROHNE primary elements (e.g. orifice plates or pitot tubes). Equipped with diaphragm seals, it is the right choice for hydrostatic level, interface, density or demanding DP process applications. 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 7060 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:
Total 3D linearization
For a robust and accurate differential pressure measurement, even under changing process conditions, each OPTIBAR DP 7060 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.
Modularity
- 7 different housings (plastic, stainless steel, epoxy-coated aluminium; one chamber, two chamber)
- 4 different configuration options (DTM DDs, display, USB)
- Wetted materials: 316L NACE, Duplex, Hastelloy® C-276, 316L with gold plating
- Pressure rating up to 400 bar/ 5800 psi
Remote option
The remote sensor option provides several advantages for a pressure measurement installation. Confined spaces, which do not allow for convenient setup or control of the transmitter, benefit from a remote transmitter mounting up to 25 m away from the sensor unit. Additionally, the sensor unit is rated IP68 (25 bar), allowing for complete submersion under water for an infinite time – gauge pressure sensors then use the internal venting capillary for ambient pressure reference.
Integrated absolute pressure measurement
The OPTIBAR DP 7060 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.
