Process Instrumentation
Measurement and control in continuous industrial processes
Reliability, safety and operational continuity of the plant
Process instrumentation plays a central role in industrial plants involved in fluid transformation, treatment and management. In this context, the measurement of parameters such as pressure, temperature, level and flow is not only functional to operational control, but is a key element for plant safety, production continuity and regulatory compliance.
Fluid System supplies process instrumentation solutions selected for reliability, robustness and compatibility with demanding application conditions. The offering is based on collaboration with Wika and Elettrotec, reference brands for industrial measurement and control, able to cover both standard requirements and special process applications. These solutions differ from those used in industrial automation in terms of selection, configuration and installation criteria, as they are designed for continuous-duty systems, critical environments and complex industrial fluids.
In process applications, instrumentation is not only about measurement: it often also involves safety and regulatory compliance. Dedicated versions are available for ATEX environments, hygienic applications and regulated contexts, depending on the sector and the fluid handled.
Types of Process Instrumentation
Devices designed for pressure, vacuum and temperature control and signalling in process plants. They are used for safety, alarm and interlock functions, where long-term reliability and stability of the switching point are required. A wide range of diaphragm and seal materials is available (NBR, FKM, EPDM, silicone, stainless steel) to ensure chemical compatibility with process fluids.
Brands: WIKA, ELETTROTEC
PROCESS PRESSURE GAUGES
Instruments for local pressure indication, used for direct monitoring of plant status. In process applications, build quality, wetted materials and protection against vibration, pulsation and aggressive environments are particularly important.
Brand: WIKA
PROCESS PRESSURE TRANSDUCERS
Electronic sensors for continuous pressure measurement and signal transmission to control systems. They are used when measurement must be integrated into process supervision, control and monitoring systems.
Brand: WIKA, ELETTROTEC
LEVEL AND FLOW SENSORS
Solutions for level and flow control in tanks, vessels, lines and process auxiliary services. Used to ensure operational stability, prevent critical conditions and support plant management.
Brands: WIKA, ELETTROTEC
VSM Series
Elettrotec industrial vacuum switches
Adjustable vacuum switches designed for vacuum control and signalling in industrial circuits. Used for safety, alarm and interlock functions, they enable electrical switching when the set value is reached, ensuring long-term reliability and switching-point stability even under demanding operating conditions.
232.50 Series
Wika process pressure gauges
Bourdon tube pressure gauges with stainless steel case and liquid filling, designed for local pressure measurement in process plants and industrial applications. The filling dampens vibrations and dynamic loads, ensuring stable, reliable readings and a long service life even in severe environments.
S-20 Series
Wika pressure transducers
Electronic pressure sensors designed for industrial and process applications requiring high reliability and measurement stability. They convert the pressure value into an electrical signal for integration into automation, control and continuous plant monitoring systems.
LM Series
Elettrotec float level switches
Mechanical float level switches designed for point level control in tanks and process vessels. Used for safety and interlock functions, they detect the minimum or maximum fluid level while ensuring simple construction, reliability and adaptability to different operating conditions and fluid types.
