    • The pressure cell device according to the invention serves for measuring hydraulic pressures in hydraulic mining devices in an inherently secure service region. It is provided with a connection element which can be connected to a pressure reception connection and with a sensor housing, on the inside of which is arranged a hydroelectric pressure transducer which is pressurised by the hydraulic pressure present at the pressure reception connection and converts this into an electrical signal. So as to ensure high measurement accuracy over a long operating period, without it being necessary to have exchanges of the pressure transducer or its new calibration, it is provided according to the invention that the pressure transducer comprises a ceramic pressure measuring cell.
    • 根据本发明的压力传感器装置用于在固有安全的服务区域中测量液压挖掘装置中的液压压力。 它设置有可连接到压力接收连接件和传感器壳体的连接元件,传感器壳体的内部设置有水力压力传感器,该压力传感器被压力接收连接处存在的液压加压并将其转换为 电信号。 为了确保在长的运行期间的高测量精度,无需压力传感器或其新校准的交换,根据本发明提供了压力传感器包括陶瓷压力测量单元。

    • A control device (10) for electro-hydraulic support frames with a casing (11) accommodating a circuit, several plug-in connectors (20) accessible from outside the casing (11) for the connection of control leads, and with actuating control elements (13) connected to the circuit. The control elements (14, 15, 16, 17, 18) are grouped together in several exchangeable modules (27), accommodated in the casing (11), which are connected to the circuit and to each other by plug-in connecting elements (30) when installed in the casing (11). The modules (27) are exchangeable independently of each other. The operating keys of a keyboard (16) and/or an indicator unit (18) can be combined in one operating module (28), which can be removed from the casing (11). The actual control of the control device in the casing (11) and operation of the support frame is permitted to continue during the exchange of the operating module (28).
    • 一种用于电液压支撑框架的控制装置(10),其具有容纳电路的壳体(11),用于连接控制引线的壳体(11)外部可接近的几个插入式连接器(20),以及致动控制元件 (13)连接到电路。 控制元件(14,15,16,17,18)被组合在一起,容纳在壳体(11)中的几个可更换的模块(27)中,这些可更换模块通过插入式连接元件连接到电路和彼此之间 30)当安装在壳体(11)中时。 模块(27)可彼此独立地交换。 键盘(16)和/或指示器单元(18)的操作键可以组合在一个可从壳体(11)移除的操作模块(28)中。 在操作模块(28)的更换期间,允许壳体(11)中的控制装置的实际控制和支撑框架的操作继续进行。
