摘要： During shipment or other handling events, it is necessary to protect a liquid level controller from damage by manually engaging a lever locking mechanism to secure a lever assembly of the liquid level controller. The lever locking mechanism must be manually disengaged prior to calibrating or putting the liquid level controller into operation. To better facilitate an operator in monitoring the state of the lever locking mechanism, a sensor is coupled to the lever locking mechanism to detect whether the lever locking mechanism is in a locked or unlocked position. This information is then provided to the operator via a user interface. Compared to current visual inspections, the use of the sensor is more robust and reliable, and provides a simple non-contact method for determining the state of the lever locking mechanism.

摘要： A feedthrough apparatus, such as for a passage through a barrier between a first compartment and a second compartment of a housing, can include a sleeve configured to sealingly couple with the passage, a printed circuit board (PCB) disposed through the sleeve and configured to provide electrical communication among the first compartment and the second compartment of the housing, and a seal disposed within the sleeve. The seal can be sealingly coupled to the PCB, and the sleeve, the PCB and the seal can be configured to hermetically seal the passage. The seal can include potting material and a V-groove connection.

摘要翻译：在装运或其他处理事件期间，有必要通过手动接合杠杆锁定机构来保护液位控制器免受损坏，以固定液位控制器的杆组件。在校准或使液位控制器运行之前，杠杆锁定机构必须手动脱开。为了更好地方便操作者监视杠杆锁定机构的状态，传感器联接到杠杆锁定机构以检测杠杆锁定机构是否处于锁定或解锁位置。然后，该信息经由用户界面提供给操作者。与当前的视觉检查相比，传感器的使用更加坚固可靠，并且提供了一种用于确定杠杆锁定机构的状态的简单非接触式方法。
