What is process instrumentation?

Process instrumentation refers to the various instruments and systems designed to measure, monitor, control and optimize industrial processes. These instruments are used in a wide range of industries, including oil and gas, chemicals, pharmaceuticals and many others.

Field devices such as sensors, transmitters, controllers, and analyzers are integral parts of process instrumentation. Examples include flow measurement devices, pressure transmitters, level sensors, thermometers and pH sensors and transmitters or optical analyzers.

These instruments play a critical role in industrial process control, helping companies to increase productivity, reduce downtime, and ensure compliance with regulatory standards. In the process industry, every second counts, so reliable instrumentation is essential for uninterrupted production and optimal plant performance.

What are the main tasks of measurement instrumentation?

Measurement instrumentation plays a crucial role in various industrial processes, ensuring yield, safety, and product excellence. The main tasks of measurement instrumentation are as follows:

Measurement
Measurement is the core function of process instrumentation. Instruments are used to measure critical parameters such as temperature, fluid flow rate, level, and pH. Consistently measuring these variables ensures that the manufacturing process remains stable and efficient. Measurement accuracy is essential for adhering to product standards and ensuring the final product meets the required specifications. For example, accuracy in flow measurement ensures that chemical reactions receive precise quantities of reactants, like in water treatment plants, where precise flow measurement aids in maintaining proper dosing of treatment chemicals. Similarly, precise level measurement is essential across a wide range of applications. In beverage filling, for example, it helps to prevent overfilling and dry running of syrup or mixing tanks, which are common causes of production interruptions.

Control & Analysis
Beyond measurement, process instruments are integral to controlling the various parameters in industrial operations. These components provide accurate real-time data and feedback to control systems, enabling them to adjust the process in response to changing conditions. For example, filtration processes used in the manufacturing of fruit juices, beer, pharmaceuticals, chemical products, and more are controlled using turbidity sensors. These sensors measure the purity of the filtrate, enabling early detection of filter breakthroughs. Key optical analysis technologies, such as tunable diode laser absorption spectroscopy (TDLAS), quenched fluorescence (QF), and raman spectroscopy, are used to tightly monitor and control industrial processes with exceptional speed and reliability. These systems provide 24/7 on-line and in-line measurements of chemical composition and concentration, minimizing downtime, controlling costs, and mitigating safety risks.

Monitoring
Continuous process monitoring is essential for maintaining product quality and ensuring process reliability. It provides real-time information enabling the early detection of any deviations from normal operating conditions. This enables operators to identify potential issues before they escalate into more significant problems. For example, continuous pressure monitoring in critical systems such as pipelines, steam boilers, or reactors in the energy industry enables early detection of leaks, blockages, or build-up.

What are the benefits of process measurement?

Instrumentation is crucial for industrial manufacturing and process control, ensuring that fabrication processes are both manageable and economically viable. It also offers several other benefits:

Automation
Instruments that monitor and control processes lead to increased automation in industrial plants. Control systems continuously collect and analyze real-time process data, enabling individual parameters to be adjusted to maintain optimum process conditions. Optical analysis technologies provide real-time measurement data for valuable process transparency for manufacturers. Integrating these technologies with industry-standard automation platforms enables continuous data collection and analysis, advanced diagnostics, self-calibration, and remote accessibility, ultimately leading to improved productivity and reduced operational costs. Automated level measurement in storage tanks, for example, enables digitalization of material logistics. Continuous real-time data supports accurate demand forecasting, reduces transportation, and ensures consistent material quality.

Improved safety
Process control systems continuously collect information from sensors and process it for further distribution or action. They can automatically instruct other components to adjust if an anomaly is detected, and alert operators when any parameter exceeds a safe threshold, reducing the risk of equipment damage, accidents and other incidents. This is particularly important in heavy industries with processes involving hazardous materials, high pressures or extreme temperatures, as it protects human health and minimizes risk to the plant, equipment and environment. Instrumentation can detect extreme conditions, such as the presence of hazardous gases, and trigger alarms or activate emergency shutdown systems. By providing continuous, fast and precise temperature measurements, abnormal conditions can be detected early to prevent hazards such as the overheating of explosive materials. In addition, accurate pressure measurement helps to identify leaks or blockages in pipelines at an early stage, reducing the risk of equipment failure.

Enhanced efficiency
Process instrumentation improves plant performance by providing operators with accurate, real-time data that they can use to monitor and adjust process parameters for maximum output, minimum waste and reduced energy consumption. It helps to identify wasteful and inefficient manufacturing techniques, resulting in significant cost savings. Advanced diagnostics further improve the efficiency of measurement instrumentation devices. Monitoring and recording the process data for utilities using system products such as energy managers is the basis for improving efficiency. For example, this can involve identifying energy waste in steam networks. Flowmeters improve efficiency by providing accurate and repeatable measurements of process fluids and their utilities, thus forming the basis for monitoring performance indicators. Multivariable flow measurement devices, such as coriolis flow meters, can identify issues affecting efficiency by monitoring factors such as density, viscosity, conductivity, temperature, pressure and the dryness fraction of steam. Using calibrated devices and recalibration services ensures compliance with standards such as ISO 14001 (environmental management) and ISO 50001 (energy management).

Improved product quality
Measuring devices ensure that all critical process parameters are maintained within their intended ranges. By controlling these variables, the components help ensure consistent products that meet the required industry and regulatory standards. The reliability of measurement devices is paramount. For example, in the production of active pharmaceutical ingredients (APIs), product integrity and yield are optimized by measuring pH and oxygen concentration. In fermentation processes in the food and beverage industry, accurate temperature measurement is essential for achieving the best possible product and avoiding unwanted flavours.

What is an example of measurement instrumentation?

Dairy processing is a food and beverage application that involves stringent standards. Before milk reaches supermarket refrigerated shelves, it undergoes several processing stages at the dairy. Process instrumentation plays a crucial role in ensuring the highest product quality in this hygienic processing plant, keeping the milk healthy and safe while minimising the waste of raw materials and energy.

These solutions are used throughout the dairy production process:

Flow measurement is important throughout the dairy process, from milk reception and transportation through the dairy, to the control of raw material supply to different process steps, as well as the measurement of final or intermediate products. Mass balance and allocation are important to ensure transparency of losses and resource consumption.
Level measurement is essential for reliable monitoring of tank inventory during milk storage and processing. Capacitive and hydrostatic sensors provide precise level data even under challenging conditions such as foam formation or condensation. Free space radar sensors offer a flexible and scalable solution for a wide range of applications in milk processing. Additionally, point level detection prevents tank overfilling and protects pumps from running dry.
The pasteurization process requires milk to be heated to a specific temperature for a defined holding time to destroy all bacteria that can be harmful to health and reduce the shelf life of dairy products.

In milk processing, pressure measurement is crucial for maintaining stable and hygienic conditions throughout various production stages. Pressure sensors help to preserve milk quality, ensure consistent heat transfer during pasteurization, and monitor pipe pressure during CIP (Cleaning-in-Place) or SIP (Sterilization-in-Place) processes to detect leaks or valve malfunctions. For homogenization, specialized sensors capable of withstanding pressures of up to 400 bar are required.
Data managers record tamper-proof process data to ensure quality control
Liquid analysis devices measure milk quality during milk reception (pH and conductivity) and monitor the cleaning of process pipes and tanks (conductivity and turbidity).
Raman spectroscopy provides real-time, inline composition analysis of liquid milk quality, dairy solids, and macronutrients. It measures multiple parameters with a single probe and enables easy scalability from lab to process.
