Instrument Identifiers
Sensed Parameter
Type of Indicator
or Controller
Type of Component
Type of signal
F = flow
T = temperature
P = pressure
I = current
L = level
V = voltage
Z = position
R = recorder
I = indicator
C = controller
T = transmitter
M = modifier
E = element
I
= current
V = voltage
P
= pneumatic
The first three columns above are combined such that the resulting instrument identifier indicates
its sensed parameter, the function of the instrument, and the type of instrument. The fourth
column is used only in the case of an instrument modifier and is used to indicate the types of
signals being modified. The following is a list of example instrument identifiers constructed from
Table 1.
FIC = flow indicating controller
FM = flow modifier
PM = pressure modifier
TE = temperature element
TR = temperature recorder
LIC = level indicating controller
TT
= temperature transmitter
PT
= pressure transmitter
FE
= flow element
FI
= flow indicator
TI
= temperature indicator
FC
= flow controller
