LE 22型电子式磁耦合油位计 |
| 此磁耦合式油位计为强水密封性的铝合金材质，表面喷涂耐腐蚀漆层。 内部浮球连杆通过磁外表在120°角度内同步联动。 按此联动方式，液位的任何变化将通过磁体的耦合转动引起油位计指示表盘的同步指示。油位计标识盘为红、白进行标识。 油位计标度盘为钢化玻璃材质，表面印刷有变压器油在如下温度时的液位显示标识：-20°C, +20°C, +85°C。 注：根据用户要求可定制特殊度盘。 |

Electronic oil level indicator type LE 22 |
| The level gauge with magnetic joint is composed of a sturdy, watertight body made of aluminium alloy that is painted to protect against corrosion. The movement of the float rod and the gauge disk takes place thanks to magnetic coupling and reaches a 120° angle. In this way, for every variation in the level of liquid there is a corresponding rotation of the magnet with consequent variation of the indication on the dial of the gauge. The gauge disk is white and red. The system is closed with a screen-printed tempered glass disk with reference marks corresponding to the levels that the oil should reach at the following temperatures in degrees Centigrade: -20°C, +20°C, +85°C. Note: special dials can be made upon request. |
