IfcSensorType

Definition from IAI: An IfcSensorType defines a particular type of sensor which is used for detection in a control system such as a building automation control system.

HISTORY: New entity in IFC 2x2

Use Definitions

An IfcSensorType provides for all forms of sensor.

Usage of IfcSensorType defines the parameters for one or more occurrences of IfcDistributionControlElement. Parameters are specified through property sets that are enumerated in the IfcSensorTypeEnum data type.

Property Set Use Definition:

The property sets relating to the IfcSensorType defined by the IfcPropertySet and attached by the IfcRelDefinesByType relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to an IfcSensorType are part of this IFC release:

Pset_SensorTypeCO2Sensor: specific property set for the properties of a CO2 sensor, if available
Pset_SensorTypeFireSensor: specific property set for the properties of a fire sensor, if available
Pset_SensorTypeGasSensor: specific property set for the properties of a gas sensor, if available
Pset_SensorTypeHeatSensor: specific property set for the properties of a heat sensor, if available
Pset_SensorTypeHumiditySensor: specific property set for the properties of a humidity sensor, if available
Pset_SensorTypeLightSensor: specific property set for the properties of a light sensor, if available
Pset_SensorTypeMovementSensor: specific property set for the properties of a movement sensor, if available
Pset_SensorTypePressureSensor: specific property set for the properties of a pressure sensor, if available
Pset_SensorTypeSmokeSensor: specific property set for the properties of a smoke sensor, if available
Pset_SensorTypeSoundSensor: specific property set for the properties of a sound sensor, if available
Pset_SensorTypeTemperatureSensor: specific property set for the properties of a temperature sensor, if available

Geometry Use Definitions

Representations of the type are defined as representation maps (at the level of the supertype IfcTypeProduct). These are assigned at the occurrence through the IfcShapeRepresentation.Item being an IfcMappedItem.
