Expert Solution
(a) A temperature (sensing) element (TE) in the plant is connected via a capillary line to a temperature transmitter (TT) also located in the plant. The TT sends an electrical signal to temperature high (TAH) and temperature low (TAL) alarms located on the front of a panel in the control room.
(b) A level switch (LS) located in the plant sends an electrical signal to …
(c) A pressure control valve (LCV) located in the plant is connected by a pneumatic (air) line to the stem of a control valve.
(d) A local flow indicator (FI) is attached to a flow orifice both instruments are located in the plant.
(e) A safety (pressure) relief valve is shown attached to two process lines. The top process line appears to vent to atmosphere but could be attached to a flare system – there is not enough information to determine this based on the sketch provided.
