KROHNE PRESSURE MEASUREMENT – FOR A SUBTLE DIFFERENCE

As a main instrumentation vendor (MIV), KROHNE ensures customer satisfaction by supplying the entire range of process instrumentation. Our pressure measuring technology is the proverbial icing on the cake. On this page discover how technology, know-how, material and experience can make all the subtle difference – with superior results for you, the customer.

Pressure is one of the most commonly measured parameters in the process industry. It is used to measure the flow, level and even the process pressure directly. Uses range from standard applications and harsh environments to extreme pressures and temperatures or even high-precision applications for acceptance measurements.All of these require a lot of experience and measuring know-how, which we have been offering for over 100 years. Our technologies, such as 3D linearisation and our extensive product portfolio, allow us to create technical solutions perfectly tailored to your requirements.

WHEN TECHNOLOGY MAKES THE DIFFERENCE

To deliver reliable values even under difficult conditions, we have integrated a number of high-end technologies into our products.

Whether hot or cold, under high pressure, abrasive or aggressive, flow rate, level or process pressure: the requirements in industrial processes are wide-ranging. Modern pressure measurement equipment has to meet ever-increasing standards with regard to safety, reliability and long-term stability. Changes to the process conditions present a particular challenge, because they can affect the actual measurement uncertainty.
KROHNE is the only manufacturer in the world to offer full 3D linearisation, which identifies and effectively offsets all factors influencing the process. All of the latest communication options from Bluetooth to IO-Link and innovative product features, such as integrated overload protection and temperature compensation, add the finishing touch to our products.

DECISION-MAKING TOOL

Which is better suited to your applications: electronic differential pressure or conventional differential pressure?

Your benefits

  • Pressure transmitters in all power categories from ultra-compact to process
  • Precise measurements with long-term stability, even under difficult process conditions thanks to 3D linearisation

WHEN EXPERTISE MAKES THE DIFFERENCE

Every process is unique. Which is why the method must be optimally selected and designed for the respective application, regardless of whether it involves measuring the fill level, flow rate or pressure. Electronically measuring pressure as a physical variable is usually very challenging. How can, for example, unwanted influences from temperature, long-term effects, over-pressure events and surges be kept to a minimum?

Our pressure transmitters embody decades of experience. In practice, OPTIBAR pressure transmitters offer impressively precise results with long-tern stability, even in challenging process conditions. All the while, you benefit from KROHNE’s comprehensive measuring know-how thanks to the vast application knowledge of our engineers and service technicians.

From simple, low-cost solutions to particularly sophisticated applications at high pressures or extreme temperatures: we will find the optimal solution for your measuring task competently and quickly.

WHEN MATERIAL MAKES THE DIFFERENCE

Choosing the right material is crucial for process reliability and efficiency. That is why KROHNE offers a premium material in its OPTIBAR pressure measurement devices for measuring pressure. It features oxide ceramic diaphragms, making it permanently resistant to corrosive and abrasive media and impervious to thermal shocks.

The OPTIBAR series also offers a wide range of pressure transmitters, diaphragm seals, primary elements and other accessories for diverse industrial requirements. With our ultra-compact, compact and process class, we can always offer the right instrument and the right material.

Ranging from stainless steel 316L as standard to ceramic, Hastelloy®, tantalum, titanium, Monel®, Duplex® to coatings such as gold or rhodium, there are plenty of options to suit many different requirements.
