7.32 MeasurementsType ObjectType Definition ToC Previous Next

The MeasurementsType provides Objects and Variables used for measurements performed at a Pump. It is illustrated in Figure 18 and formally defined in Table 73. For the generation of events, the MeasurementsType has a reference to the 0:LimitAlarmType. The InputNode Property of the Alarm shall contain the NodeId of the Component. Measurements defined in this ObjectType have an additional Subcomponent with the TypeDefinition 0:PropertyType and the BrowseName KindOfQuantity defined in Table 72. In this Variables the measurements can be matched to a physical quantity. To comply with this Companion Specification, the default values for the Property 0:EngineeringUnits and the Property KindOfQuantity provided in Table 73 should be used. The values should be sensible to the use of the application.

   SoundPressureLevel
   KindOfQuantity
“sound level” Logarithm of the ratio of a given sound pressure to the reference sound pressure of 20 μPa, the sound pressure being obtained with a standard frequency weighting and with a standard exponential time weighting. Sound level in decibels is twenty times the logarithm to the base ten of that ratio
