Process instrumentation is an integral part of any process industry because it allows real-time measurement and control of process variables like flow, pressure, levels, temperature, pH, and humidity. With the right instrumentation, process plants can run effectively, efficiently, economically and safety through the integration of alarm signals.
In oil and gas industries, the instrumentation is used to monitor and control the operating conditions of the facility, which helps to meet safety, environmental regulations, quality and productivity, profitable operation and stable plant operation objectives. Process Instrumentation can be categorized into two main branches due to their function. Devices which are used to measuring the different process variables are known as input devices and the second one is output devices of the control system which acts relative to the measured parameters to institute the required control action.
The major important parameters like pressure, temperature, flow, and level are measured by input devices. There are three main components by which the instrumentation consists, which are –
A sensor, which is sometimes called a primary measuring element, to measure required physical properties
A transducer, which converts the sensor signal into a standard signal form that suits the control system such as a pneumatic signal (3-15 psi), an electric signal (4-20 mA), a digital signal of Foundation Fieldbus, etc.
A transmitter, which prepares the transducer signal for transmission without loss and then transmits it. Smart transmitters also send meaningful data about the status of the measuring instrument as a whole.
Process instrumentation includes the most common element, the control valve, which consists of an actuator that converts the output signal from the control system into a signal that can allow the valve to respond, positioned for adapting the response and the valve.
Recent developments include modifications and adaptations to suit a wider range of applications with new levels of accuracy, reliability, integrity and better price. New technologies in control valves for severe applications result in greater reliability and operability. However, the most effective new technology is smart positioners, which supply new features about self-diagnostic and analysis capability.
The challenge is to get the most benefits from data by applying analysis techniques using special software tools to support decision-making regarding optimized cost, waste reduction and enhanced productivity.
