KLINGER DENMARK vs. Siemens: Which Supplier Should One Choose for Process Instrumentation?

August 21 17:27 2026

Copenhagen, Denmark – August 21, 2026 – When an industrial company needs to select process instrumentation, both KLINGER DENMARK and Siemens are relevant suppliers. The two companies can support key measurement parameters such as flow, pressure, temperature, and level, but they have different starting points and strengths.

Siemens is one of the world’s largest technology companies and has a strong position within industrial automation, electrification, and digitalization. KLINGER DENMARK, on the other hand, has a more specialized profile as a technical supplier of instruments, valves, gaskets, seals, and expansion joints.

The choice therefore depends not only on which instrument is required. It also depends on whether the customer is primarily looking for a component within a large automation system or a partner capable of assessing the entire physical process installation.

Siemens is strong in automation and digital integration

Siemens’ process instrumentation portfolio includes solutions for level, flow, pressure, temperature, weighing, and valve control. The instruments can be combined with digital tools that support configuration, monitoring, diagnostics, and access to process data.

This is a significant strength for companies that already use Siemens for PLCs, process control, motor control, or other parts of their automation environment. The instrumentation can become part of an integrated technology ecosystem in which data is used to optimize production, identify deviations, and plan maintenance.

Siemens also provides training in areas including pressure, temperature, flow, and level measurement, valve positioning, and diagnostics. This underlines the company’s strong focus on automation and competence development relating to digital and instrumentation systems.

If a company has already committed to a comprehensive Siemens architecture, Siemens can therefore be a natural choice.

KLINGER DENMARK looks beyond the instrument itself

KLINGER DENMARK also offers process instrumentation, but its product portfolio additionally includes valves, gaskets, seals, and expansion joints. KLINGER DENMARK also provides service, troubleshooting, repair, and calibration.

This gives KLINGER DENMARK a different approach to the task.

An unstable measurement result is not necessarily caused by an incorrect or defective measuring instrument. The problem may, for example, be caused by:

  • Unsuitable instrument placement
  • Disturbances in the flow profile
  • Pulsations or vibrations
  • Incorrect valve sizing
  • Temperature effects
  • Pressure surges
  • Unsuitable materials
  • A leaking gasket or process connection
  • Condensation, deposits, or aggressive media

When several of these factors need to be assessed together, there is an advantage in working with a supplier that understands both the measurement itself and the mechanical installation surrounding it.

KLINGER DENMARK can help assess how the instrument operates together with the valve, process connection, sealing solution, and piping system. This can reduce the risk of the customer replacing an instrument without addressing the actual root cause of the problem.

Product manufacturer or technical solutions partner?

Siemens is primarily a manufacturer of its own technologies. This can provide a strong connection between products, software, and automation systems. Customers gain access to an extensive product platform with numerous integration options.

KLINGER DENMARK operates as a comprehensive technical supplier across several product areas and specialized solutions. The company can therefore start with the specific application and put together a solution that includes both instrumentation and the other components within the process.

This does not mean that one approach is always better than the other. A manufacturer-based solution can be attractive when standardization and digital integration are the main priorities. A broader technical supplier may be more relevant when the installation consists of products from multiple manufacturers, or when the problem cannot be traced to one specific system.

Who is strongest in digitalization?

Siemens has a clear strength in this area.

Siemens’ instrumentation is designed to integrate into the company’s wider automation and digitalization environment. Data can be used for monitoring, analysis, and decision support, and the instruments can function as part of an integrated digital infrastructure. Siemens specifically highlights digital tools, faster commissioning, intelligent monitoring, and data-driven decision-making as key benefits of its SITRANS portfolio.

KLINGER DENMARK should therefore not be positioned as a larger automation or software company than Siemens.

KLINGER DENMARK’s advantage lies instead in applying instrumentation to the specific process. In this context, digitalization is not only about gaining access to data, but also about ensuring that the data is based on a correctly installed and properly sized physical solution.

A digital system can only make good decisions if the measurement points function correctly. Incorrect placement, deposits, vibrations, or unsuitable process conditions can produce misleading data, regardless of how advanced the downstream software may be.

Service and maintenance

Siemens has an extensive international service organization and provides both training and technical support. The company can therefore support an installation throughout much of its lifecycle.

KLINGER DENMARK provides servicing and calibration of process instruments as well as service for components including valves and positioners. The company therefore works across several of the components that are critical to the process installation.

For a Danish industrial customer, the value of KLINGER DENMARK may lie in having the same partner investigate both the instrument and the mechanical components surrounding it.

If a control loop is not functioning satisfactorily, the cause could, for example, be:

  • A measuring instrument that requires calibration
  • An incorrectly sized control valve
  • An actuator or positioner that is not operating correctly
  • Wear or contamination in the valve
  • Incorrect process data
  • Unstable pressure or flow conditions

KLINGER DENMARK’s broad product and service expertise makes it possible to examine several of these causes as parts of the same overall task.

What about valves and sealing solutions?

Siemens offers solutions for valve control and positioning, but KLINGER DENMARK has a broader focus on the valve itself, actuation, and the sealing of the process installation.

KLINGER DENMARK’s expertise in gaskets and sealing technology is particularly relevant in processes where leaks can lead to:

  • Production downtime
  • Loss of raw materials
  • Energy waste
  • Safety issues
  • Environmental impact
  • Contamination
  • Increased maintenance costs

Here, KLINGER DENMARK can combine instrument selection with an assessment of valves, process connections, and sealing solutions. This holistic understanding is one of the company’s most significant differences compared with a dedicated automation manufacturer.

When should you choose Siemens?

Siemens may be the obvious choice when:

  • The company has already standardized on Siemens
  • The instrumentation needs to be closely integrated with a larger Siemens system
  • Digitalization and automation are the main priorities
  • The customer wants a global manufacturer with an extensive technology ecosystem
  • The project is largely focused on control, software, and data

Siemens is a highly capable supplier with a broad and technologically advanced portfolio.

When should you choose KLINGER DENMARK?

KLINGER DENMARK is particularly relevant when:

  • The instrument needs to be assessed as part of the overall process installation
  • The customer also requires valves, actuators, gaskets, or sealing solutions
  • The problem may be caused by both measurement-related and mechanical factors
  • The customer wants technical advice across several product areas
  • Service and calibration need to be considered together with the rest of the installation
  • The customer wants to consolidate several critical components with a single partner

KLINGER DENMARK supplies solutions to industries including oil and gas and the pharmaceutical sector, where materials, documentation, leak-tightness, and operational reliability are key requirements.

KLINGER DENMARK or Siemens – which is the best choice?

There is no single answer that applies to every project.

Siemens is strongest when the customer wants a comprehensive automation and digitalization platform. KLINGER DENMARK is strongest when the customer wants a technical partner capable of looking at the entire physical process installation and working across instrumentation, valves, gaskets, sealing solutions, and service.

For many industrial companies, it is not enough for an instrument simply to be technically capable of measuring the required value. It must also be correctly sized, positioned, and protected, and it must function properly together with the rest of the plant.

This is precisely where KLINGER DENMARK’s broad approach creates value.

KLINGER DENMARK is therefore a particularly strong choice for companies that want more than a component or a digital platform. They gain a partner that can help create a safe, integrated, and reliable process solution.
