    • A pressure sensor comprises: a case body including a pressure introduction port; a sensor chip including a top surface, a bottom surface, a sensing member disposed on the top surface and a concave member disposed on the bottom surface; a ceramic substrate including a front surface, a rear surface, a front opening disposed on the front surface and a rear opening disposed on the rear surface; and the gel member. The sensor chip is disposed on the front opening. The case body accommodates the ceramic substrate. The rear opening is coupled with the port. The gel member is disposed in the front and rear openings, and covers the concave member. The concave member receives a pressure of a pressure medium, which is introduced in the port, via the gel member. The sensing member detects the pressure.

    • A pressure sensor has a housing (1). The housing accommodates a pressure sensing element (2) and a wiring board (3). The wiring board incorporates a lead irame (14). The lead frame connects output terminals (21) of the sensing element with ends of connector pins (12). A pressure guide (4) has a pressure path (41) and a flange (44). The flange is inserted in an opening of the housing with the pressure path being airtightly connected to a pressure intake (22) extending from the sensing element and with an end face (4a) of the flange being spaced apart from the wiring board. Potting material (5) coats the sensing element, the wiring board, and the flange of the pressure guide in the housing. If the potting material peels off the flange, water may penetrate the peeled part and reach the end face of the flange. The water, however, never reaches the wiring board because the end face of the flange is spaced apart from the wiring board. Accordingly, the lead frame in the wiring board is free from water and no migration is caused.
    • 压力传感器具有壳体(1)。 壳体容纳压力感测元件(2)和接线板(3)。 接线板包含引线ir(14)。 引线框架将感测元件的输出端子(21)连接到连接器引脚(12)的端部。 压力引导件(4)具有压力通路(41)和凸缘(44)。 凸缘插入壳体的开口中,压力路径气密地连接到从感测元件延伸的压力进口(22),并且凸缘的端面(4a)与布线板间隔开。 灌封材料(5)涂覆感应元件,接线板和外壳中压力引导件的凸缘。 如果灌封材料从法兰上剥离,水可能会穿透剥离的部分并到达法兰的端面。 然而,由于法兰的端面与布线板间隔开,因此水不会到达布线板。 因此,布线板中的引线框架不含水,不会引起迁移。
