- GasDetected
  P_SINGLEVALUE / IfcLabel

  | GasDetected: Identification of the gas that is being detected, according to chemical formula. For example, carbon monoxide is 'CO', carbon dioxide is 'CO2', oxygen is 'O2'.
  | 対象ガス: 検出されているガスの識別。

- SetPointConcentration
  P_BOUNDEDVALUE / IfcPositiveRatioMeasure

  | SetPointConcentration: The gas concentration value to be sensed. Use IfcPropertyBoundedValue.SetPointValue to set the set point value.
  | ガス濃度設定値: 感知されるガス濃度。 セットポイント値を置くために、IfcPropertyBoundedValue.SetPointValueを使用する。

- CoverageArea
  P_SINGLEVALUE / IfcAreaMeasure

  | CoverageArea: The floor area that is covered by the sensor (typically measured as a circle whose center is at the location of the sensor).
  | 測定範囲: センサでカバーされている床面積。(通常、センターがセンサの位置にある円として測定される)
