KROHNE Pressure measurement

General Description KROHNE offers a comprehensive portfolio of high-quality pressure measurement devices, including pressure transmitters, differential pressure transmitters, diaphragm seals, and primary elements (orifice plates) for flow measurement based on differential pressure. The OPTIBAR series features both ceramic and metallic measuring cells, designed for accurate and reliable measurement of absolute, gauge (relative), and differential pressure in liquids, gases, and steam across demanding industrial processes.

List of Types

• Pressure Transmitters:

  • OPTIBAR P 1010 — ultra-compact for basic pressure and level applications.

  • OPTIBAR PC 1010 — with ceramic diaphragm for standard tasks.

  • OPTIBAR PM 3050 — compact metallic cell for general-purpose pressure/level.

  • OPTIBAR PC 5060 — advanced process pressure and hydrostatic level transmitter.

  • OPTIBAR PM 5060 — for process pressure and level (including hygienic variants).

  • OPTIBAR P 2010 / PSM 2010 — hygienic pressure transmitters and switches.

  • OPTIBAR LC 1010 — submersible level probe for water/wastewater.

• Differential Pressure Transmitters:

  • OPTIBAR DP 3050 — for flow, level, and differential pressure in general applications.

  • OPTIBAR DP 7060 — high-accuracy for flow, level, density, and interface measurement (with static pressure integration).

  • OPTIBAR 5060 eDP — electronic differential pressure system for level, density, etc.

• Diaphragm Seals (Separators):

  • OPTIBAR DSP 2000 / DSP 3000 — threaded or flanged, with optional extensions.

  • OPTIBAR DSD 3100–3220 — flanged designs with extensions for aggressive media.

• Primary Elements for Flow (Orifice Plates):

  • OPTIBAR OP 1100 / 1110 / 3100 / 3200 / 4100 — orifice plates (RF/RTJ faces, corner taps, annular chambers) for DP-based flow measurement.

• Other: REconnect quick-coupling system for diaphragm seals.

Advantages

• High accuracy, long-term stability, and fast response times (e.g., advanced models like DP 7060).

• Wide pressure ranges (up to high pressures in some models), excellent resistance to corrosion, abrasion, and aggressive media via ceramic/metallic cells.

• Compact and modular designs for easy installation in space-limited or hygienic environments.

• Versatile: single device for pressure, level, flow, density, and interface measurements.

• Robust construction for harsh conditions, low maintenance, and options for ATEX/explosion-proof certifications.

• Seamless integration (4…20 mA/HART®, etc.) and compatibility with diaphragm seals for extreme process conditions.

Applications

• Process industries: chemicals, petrochemicals, oil & gas.

• Food, beverage, and pharmaceutical sectors (hygienic models like OPTIBAR P 2010).

• Water and wastewater treatment (submersible probes like LC 1010).

• Level measurement in tanks/silos, hydrostatic level, flow of liquids/gases/steam.

• Density and interface detection in separation processes.

• Any industrial application requiring precise, reliable pressure, level, or DP-based flow measurement in liquids, gases, vapors, or steam.
