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).

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.
