    Process Control

    The RS range of Process Control equipment is essential for managing complex processes and automation environments. A process control system allows the sophisticated, fully automated systems in an industrial facility to adjust minor parameters automatically, with no further human intervention required.

    When conditions are not as expected, the operator may record indications to evaluate the process's current state. It is not feasible and unreliable to control most processes manually due to their continuous interactive nature. It is possible to automate such processes with the help of instrumentation.

    Most industrial processes and generating systems require a consistent and reliable operation, which is made possible by instruments. To maintain a process at the desired state, instrumentation monitors, records, and controls it. This is the essence of process control.

    Whenever a process is being controlled, measurement is the first step. The parameters which need measurement are:

    • Fluid pressure
    • Fluid flow rate
    • Objects' temperatures
    • Fluid-filled vessel volume
    • Chemical concentrations
    • A machine's position
    • Motion or acceleration
    • Dimensions of an object
    • Inventory count
    • Electrical voltage
    • Resistance or current

    Typical final process control devices include:

    • Throttle valve (for controlling a fluid's flow rate)
    • An electric motor
    • Electric heaters.

    Both measurements and final controls play a role in the process.

    With everything from temperature control technologies, to panel meters, and timers, RS provides solutions and support no what your application.

    What Process Control equipment do I need?

    Whether in manufacturing or engineering, there are certain process control equipment categories that are widely used. Any commercial or production environment will benefit from

    Temperature Controllers

    Temperature Controllers are essential for controlled storage conditions, and sensors and temperature monitoring equipment ensure the safe, reliable running of mobile and static temperature-sensitive storage areas.

    Panel Meters

    Panel Meters are vital for maintaining visible control and measurement of process systems and are available in digital and analogue formats. They are essential in power measurement in electrical systems.

    Timers & Counters

    Timers and Counters are important components in the automation and control of electrical machinery and systems, allowing pre-set responses where mechanical precision is required.

    Current Transformers

    Current Transformers (CTs) are used to measure the current flowing through another circuit. High-voltage lines are monitored with CTs in power grids nationwide. In a CT, the primary current is measured in the primary winding and then an alternating current is produced in the secondary winding.

    Energy Meter

    Energy meters measure the amount of electricity being consumed, which allows for an estimate of energy usage over time.
