    • A pressure sensor includes a housing with which terminals are insert-molded, a sensing element mounted on the housing and electrically connected to the terminals, an electrically insulating protective member for covering the terminals and the sensing element. The protective member has a triple-layer structure. The first protective member for covering the terminals has high elasticity to prevent bubbles from being produced in the protective member. The second protective member for covering the sensing element has low elasticity to reduce stress applied to the sensing element. The third protective member having higher acid resistance covers the second protective member so that the sensor has high acid resistance without sacrificing the sensor characteristics.
    • 压力传感器包括:端子被插入模制的壳体,安装在壳体上并与端子电连接的感测元件,用于覆盖端子和感测元件的电绝缘保护构件。 保护构件具有三层结构。 用于覆盖端子的第一保护构件具有高弹性以防止在保护构件中产生气泡。 用于覆盖感测元件的第二保护构件具有低弹性以减少施加到感测元件的应力。 具有较高耐酸性的第三保护构件覆盖第二保护构件,使得传感器具有高耐酸性而不牺牲传感器特性。

    • A pressure sensor is provided. The pressure sensor includes a sensing element, a case, a line element, an insect entering restriction element. The case has a space for receiving the sensing element. The case includes a pressure introduction passage, which is in communication with the space to introduce a pressure medium into the sensing element. The line element has a first portion electrically connected with the sensing element and a second portion to be electrically connected to an external element. The insect entering restriction element extends across a path on the exterior surface of the case, the path interconnecting between the second portion of the line element and the open end of pressure introduction passage.
    • 提供压力传感器。 压力传感器包括感测元件,壳体,线路元件,昆虫进入限制元件。 壳体具有用于接收感测元件的空间。 壳体包括压力引入通道,其与空间连通以将压力介质引入感测元件。 线元件具有与感测元件电连接的第一部分和电连接到外部元件的第二部分。 昆虫进入限制元件穿过壳体的外表面上的路径延伸,线路元件的第二部分和压力引入通道的开口端之间的路径相互连接。
