What does TIPC mean on this PID diagram?
Thread Content
As shown in the figure below, I would like to ask the seniors: what does TIRC mean on this PID diagram?
The convention is as follows: T: Temperature, I: Indication, R: Recording, C: Control. Each design institute is different; check the image on the homepage.
TE005 is a temperature sensing element that transmits data to the DCS in the control room. TIRC005 is responsible for temperature indication and recording; it displays the temperature on the DCS, keeps track of temperature trends, and controls the opening degree of valves or dampers.
T: Temperature I: Indication R: Recording C: Control.
Generally, T: temperature, I: indication, R: recording, C: control; check the PID legend.
T: Temperature I: Indication R: Recording C: Control.
Generally, when a record R is indicated, an indicator I is not specified, because the record itself implies an indication; there is nothing that is merely recorded without any indication.
