The meaning of gauge symbols
Thread Content
What do PG, PIA, LIA, XS, * and TG all mean? Thank you
1# arespx PG denotes the pressure at the site; XS refers to the socket, while TG represents the temperature at the site. Thermometers: TG, TI, TW, TRC ； Pressure gauge: PS PI PG ； Level gauge: LIC LG LIA ； Flow meter: FIC
1# arespx I’m not sure if it’s correct, O(∩_∩)O~. . . . . . . . . . .
PG: Pressure gauge with on-site indication PIA: Pressure gauge with pressure indication alarm LIA: Level gauge with level indication alarm XS: Displacement sensor with interlock function (for reference only) *: Displacement sensor (for reference only) TG: Thermometer with on-site indication
PG refers to the pressure gauge installed on-site; PIA denotes the remote transmission and indication of pressure signals as well as alarms; LIA refers to the remote transmission and indication of level signals along with alarms; XS indicates interlock actions related to vibration or displacement – the exact meaning depends on the design specifications, but it usually refers to displacement or vibration. * denotes indications of vibration or displacement; TG refers to the local temperature gauge installed on-site
PG: Refers to a pressure gauge installed on-site. PIA: Refers to remote transmission of pressure signals for indication and alarm purposes. LIA: Refers to indication and alarm of liquid level signals. XS: Refers to interlock for displacement or vibration; generally, X denotes vibration or interlock, as defined in the design. *: Refers to indication of displacement or vibration. TG: Refers to on-site temperature indication
*It depends on which design institute prepared the drawings; the assessment by the Second Chemical Engineering Institute is pending (that is, the parameters are unknown), and these values are usually included in the data related to vibration and displacement
PG refers to the pressure gauge installed on-site; PIA denotes the remote transmission and indication of pressure signals as well as alarms; LIA refers to the remote transmission and indication of level signals along with alarms; XS indicates interlock actions related to vibration or displacement. The meaning of X depends on the design specifications, but it usually refers to displacement or vibration. * indicates vibration or displacement indication. TG refers to the local temperature gauge installed on-site. That’s all for now; you can take a look when you have time at instrument installation and reading diagrams
PG: Pressure gauge – local indication. PIA: Pressure indicator & alarm – pressure transmitter. LIA: Level indicator & alarm – level transmitter. XS: The English term for this is unknown; it generally refers to shaft vibration or shaft displacement monitoring. *: The English term for this is unknown; it generally refers to indicators for shaft vibration or shaft displacement. TG: Temperature gauge – thermometer–local indication
PG: On-site pressure gauge; PIA: Remote pressure transmitter with alarm function; LIA: Remote level transmitter with alarm function; XS: Displacement interlock function (vibrations are generally indicated by letters starting with V); TG: On-site thermometer
