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. In case of RTD (thermoresistance) sensors the IRDI 3:0112/2///61987#ABB088#002 shall be referenced, in case of thermocouple sensors the IRDI 3:0112/2///61987#ABB092#002 shall be referenced. For mapping rules see 8.2.4.

SensorType: ABB088#002 defines classification of RTDs based on material and resistance used.

SensorType: ABB092#002 defines classification of a thermocouple according to the material pair or standard type code.

SensorConnection: ABB091#002 defines classification of an RTD connection based on the number of wires used. For mapping rules see 8.2.4.

SensorReference: ABB093#002 defines type of reference junction for a thermocouple. For mapping rules see 8.2.4.
