330130-085-00-05 延伸电缆有带铠装和不带铠装两种类型

330130-085-00-05延伸电缆是指连接探头和前置器的中间部件，其安装应保证在使用过程中不易受到损坏，信号传输正常可靠。以下是延伸电缆的应用场景和注意事项：

应用场景：
管道铺设：通常不带铠装的延伸电缆采用管道铺设，若采用带铠装的延伸电缆，需确保管道铺设时不会损坏电缆。
设备连接：延伸电缆用于连接传感器探头和前置器，通常需要保证信号传输的可靠性和稳定性。

注意事项：
信号传输：在安装过程中，应保证延伸电缆的接头与信号“地”相联接，且接头金属表面应裸露，同时为了避免联接处和机壳接触，通常将延伸电缆与探头电缆相联的一端带有绝缘保护套。

电缆长度：在选型时，应保证延伸电缆的长度加探头电缆的长度之和，大于探头安装处到前置器安装处的距离。

固定与防护：过长的电缆应盘成直径不小于50mm的圆形并用绑带扎紧后固定，不能随意剪断或加长电缆，否则会造成传感器系统特性的变化。

选型与安装：延伸电缆有带铠装和不带铠装两种类型，在选型时需根据实际应用场景选择合适的类型。在安装时，应将延伸电缆接头与探头高频接头用手拧紧联接好，然后将套管套在接头处，起到绝缘和保护作用。

330130-085-00-05 Extension cable refers to the middle part connecting the probe and the preprocessor, and its installation should ensure that it is not easy to be damaged during use, and the signal transmission is normal and reliable. The following are the application scenarios and precautions for extension cables:

Application scenario:
Laying pipes: Generally, unarmoured extension cables are laid through pipes. If armoured extension cables are used, ensure that the cables are not damaged during laying.
Device connection: Extension cables are used to connect sensor probes and precursors, usually to ensure the reliability and stability of signal transmission.

Note:
Signal transmission: During the installation process, it should be ensured that the connector of the extension cable is connected to the signal “ground”, and the metal surface of the connector should be exposed, and in order to avoid contact between the connection and the housing, the end of the extension cable and the probe cable are usually connected with an insulating protective sleeve.

Cable length: In the selection, it should be ensured that the sum of the length of the extended cable plus the length of the probe cable is greater than the distance between the probe installation and the preloader installation.

Fixed and protection: too long cable should be coiled into a circle with a diameter of not less than 50mm and fixed after binding, do not cut or extend the cable at will, otherwise it will cause changes in the characteristics of the sensor system.

Selection and installation: There are two types of extension cables with and without armor. Select an appropriate type based on the actual application scenario. During installation, the extension cable joint and the probe high-frequency joint should be tightly connected by hand, and then the sleeve is placed on the joint to provide insulation and protection.
