KROHNE introduces complete pressure portfolio

Product News Tuesday, July 14, 2015: KROHNE Pty Ltd

• OPTIBAR seriescovers process pressure ,hydrostatic pressure and differential pressure applications
• Pressure tranmitters with ceramic or metallic measuring cells ,differential pressre(DP) transmitter wth intergrated absolute pressure measurement an high overload resistance
• Modular concept for all OPTIBAR PC,PM as DP transmitters
• Complete masuring points for flow ,level or process pressure appliations

With the release of the OPTIBAR series, KROHNE is extending its range of process instrumenation to include pressure measurement. Since the release of the first compact pressure transmitter in 2012 ,KROHNE has been continuously working on its own pressure portfolio. With ACHEMA 2015 , a complete portfolio for process pressure ,hydrostatic pressure and differantial pressure is unveiled . The new OPTIBAR series includes a variety of pressure transmitters with ceramic or metallic measuring cells ,applications specific diaphragm seals ,primary elements and accessories to equip flow ,level or process pressure applications -from single transmitters to complete measuring points.

Starting with transmitters ,the portfolio holds pressure transmitters with ceramic or metallic measuring cells for standard applications:OPTIBAR PC 5060 with capacitive ceramic measuring cell is aimed at all applications up to +100 bar/+1450 psi gauge.OPTIBAR PM 5060 with metalic measuring cell and fully welded process connection is used for high pressures up to +1000 bar/+14504 psi gauge,aseptic processes ,and in combination with diaphragm seals, for high temperature or corrosive applications . Compact and ultra-compact transmitters ,e.g. forOEM applications, are also available.

The differential pressure (DP) transitter OPTIBAR DP 7060 marks the centre of the transmitter range. It can be used for either flow ,level or process pressure applications up to 420 bar/ 6091 psi. The intergrated absolute pressure measurement eliminates the need for additional sensor in flow and level applications ,e.g. to measure head pressure in closed/pressurized vessels. Smallest measuring span of 10mbar/ 0.145 psi gauge is ideal for applications with small turndown ratios, and quick step response times allow fo use e.g with pulsating flows.

All OPTIBAR PC,PM and DP transmitters are based on a modular concept and share interchangeable housings ,eletronics,display and adjustment modules. hereby, different requiremets such as intrinsically safe /explosion proof concepts or 4....20mA HART 7/ HART SIL 2/3, FOUNDATION fieldbus,PRFIBUS PA cmmunication options can be met with just one platform for DP volume or mass flo measurement of liquids ,gases or steam,KROHNE offers a wide porfolio from primary elements to complete measuring points from one source with matched, pre-configured components . Medium temperatures -200....+1000⁰C/ -328....1832⁰F can becovered.

As primary elements ,averaging pitot tubes are available as a simple, cost-efficient and long term stable alternative next orifice plates. Pitot tubes are especially suitable for applications that require a low pressure loss ,retrofit of exsting pipes with a  flow measurement,line sizes >DN300/ 12",or low pressure gases. The portfolio as includes wet-calibrated meter runs for small line sizes an low measurement uncertainty, a flow computer ,optional pressure and temperature compensation as well accessories safe and easy installation of pressure transmitters in the process such as as valves and manifolds ,condensate pots, or general accessories . Al DP flow instruments can be wet calibrated up to DN3000/ 120".

Hydrostatc pressure is used to measure liquid level,density or liquid-liquid interface in open and pressurized vessels of any size. The OPTIBAR modular product line offers a complete portfolio of pressure an DP transmitters,diaphragm seal and accessories for measurement of corrosive and non-corrosive liquids and slurries up to 450⁰C /+842⁰F /6091 psi.

As a simple level measurement solution for wells or tanks,submersible probes are available . A large portfolio of process connections,including different hygienic proces connections fo a hygienic ,dead zone-free installation ,covers the requirements of various industries.

The OPTIBAR modular product also covers process pressure applications to measure pressure in pipes or vessels from -1....+1000 bar / -14 ...+14504 psi gauge and +....+600bar/0....+8702 psi gauge aboslute. Over 250 thread,flange and aseptic process connections are available for different industry standards ,including special materials. As standard transmitters cover process temperatures up to +150⁰C/+302⁰F without diaphragm seal. For  temperatues up to +450⁰C /+842⁰F or corrosive mediums ,OPTIBAR DS diaphragm seals are available,also pre-configured with direct, capilary or combined direct/capillary mounting.
