    • The present invention provides a sensor unit (10) connectable in a water pipeline of a water system comprising a domestic water heater. The sensor unit comprises a housing (11, 12), a pressure sensor (13) located in the housing (11, 12) and operable to provide an electrical signal indicative of water pressure, and a temperature sensor (14) located in the housing (11, 12) and operable to provide an electrical signal indicative of water temperature. The housing (11, 12) has a communication aperture (17) in a surface thereof which allows communication of water pressure to the pressure sensor (13) located in the housing (11, 12). The housing (11, 12) has an arm (16) which when the sensor unit (10) is connected in the water pipeline extends towards the centre of the water flow and which has located therein at least a part of the temperature sensor (14).
    • 本发明提供一种可连接在包括家用热水器的水系统的水管道中的传感器单元(10)。 传感器单元包括壳体(11,12),位于壳体(11,12)中的压力传感器(13),并且可操作以提供指示水压的电信号;和温度传感器(14),位于壳体 (11,12)并且可操作以提供指示水温的电信号。 壳体(11,12)在其表面中具有连通孔(17),其允许将水压传递到位于壳体(11,12)中的压力传感器(13)。 所述壳体(11,12)具有臂(16),当所述传感器单元(10)连接在所述水管道中时,所述臂(16)朝向所述水流的中心延伸并且其中位于所述温度传感器(14)的至少一部分 )。
