8.3 TemperatureMeasurementVariableType

The TemperatureMeasurementVariableType is a subtype of the AnalogSignalVariableType. It is formally defined in Table 237.

This type defines temperature and is formally defined by ABA927#005.

ABA927#005 defines for a physical system exchanging quantities of heat with two bodies, during a reversible cycle, a positive state quantity characterizing each body and proportional to the quantity of heat exchanged with this body (Temperature).

For SensorType there are two possible IRDIs as target of the HasDictionaryEntry reference, depending on the kind of the connected sensor or chosen by SensorClass In case of RTD (thermoresistance) sensors the IRDI 3:0112/2///61987#ABB088#003 shall be referenced, in case of thermocouple sensors the IRDI 3:0112/2///61987#ABB092#003 shall be referenced. For mapping rules see 8.2.4.

SensorType: ABB088#003 defines classification of RTDs based on material and resistance used.

SensorType: ABB092#003 defines classification of a thermocouple according to the material pair or standard type code.

SensorClass: ABF288#004 defines setting of the sensing element type that is or should be connected to the device.

SensorConnection: ABB091#003 defines classification of an RTD or resistor connection based on the number of wires used. For mapping rules see 8.2.4.

SensorReference: ABB093#003 defines type of reference junction for a thermocouple. For mapping rules see 8.2.4.

The components of TemperatureMeasurementVariableType have additional references which are defined in Table 238.

The child Nodes of the TemperatureMeasurementVariableType have additional Attribute values defined in Table 239.
