Foxboro recorders and controllers have earned a reputation for accuracy, reliability and innovation. > For more information, go to Foxboro recorders, controllers and configurators are the perfect complementary instruments to the measurement devices you use to operate your plant. (5) To define the Y function on a diagram, add the specific symbol of the relay or convert to a square of 6 mm on the side of the graphical sign of the instrument (in the north-east position).WARNING: These products can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. (4) Very low or minimum is indicated with LL

(3) Very high or maximum is indicated with HH (2) Glass instruments that allow the visualization of process data For example C – Conductivity D – Density etc. (1) It must be chosen uniquely for each project. – Table 4 identifying the safety conditions of the valves and actuatorsĪt the end will also be reported the literal and graphic symbols of the power supplies and signals of the instrumentation. – Table 3 the graphic identification of the actuators – Table 2 the graphic identification of the valves – Table 1 identifying the function of the instruments or devices Graphical representation of a temperature recorder controller of the 101A loop, suitable for control room mounting

If an instrument has a circumscribed square means that it is an integrated instrument as a function in a DCS (Distributed Control System) or PLC (Programmable Logic Controller).

No line in the center: for an instrument suitable for field application.

The dotted line in the center: for an instrument suitable for technical room mounting.

Continue Line in the center: for an instrument suitable for control room mounting.

The circle that identifies the instrument or device has: The symbology of the instrument it is placed in a circle of 7/16 “or 12 mm (see below), was in the top there is the functional identification (of the instrument or device) composed with max 5 letters, and in the bottom there is identification of the loop (measurement and/or control) consists of a progressive number of 3 or 4 numbers, followed by a literal suffix to identifies two or more identical instruments inserted in the same chain and therefore having the same functional identification The symbology for the identification of the measurement and control instrumentation on the flow and process diagrams and on the P&ID (Piping & Instrument Diagram), commonly called P&I (Piping & Instrumentation), is generally compliant with the Standard ISA (Instrumentation Society of Automation) identified as S.5, that is composed of identification codes and graphic symbols.

electrical machines (motors, generators, and turbines).

piping components (pipes, flanges, and fittings).

The most common P&ID symbols are listed below:

The ISA S5.1, ISO 10628, and BS 5070 cover the standardization of P&ID symbols and guide process engineers in their plant design activities. P&ID symbols exist for all major components and lines, such as valves, vessels, instruments, pumps, compressors, and towers. a very detailed diagram showing the processes happening within a plant, the involved equipment, and their interconnections.Ī set of standardized P&ID symbols is used by process engineers to draft such diagrams. P&ID is the acronym for “Piping and instrumentation diagram”, i.e.
