Fuel tank oil level travel monitoring instrument HXW-U

When the steam turbine rotates continuously at high speed, it needs to be equipped with a dedicated oil tank to continuously lubricate and conduct heat to its rotating components. Therefore, it is necessary to use an oil tank level monitoring device and connect it to a linear displacement sensor to monitor the liquid level in the oil tank. When the liquid level drops below a certain value, lubricating oil needs to be added to maintain the operation of the steam turbine to prevent accidents.

Function Description (Intelligent Type)

1. Realize intelligent processing: Alarm values I and II can be set arbitrarily through panel buttons

2. The panel buttons can adjust the range value without the need for potentiometer adjustment, making it convenient for on-site debugging

3. If you don't press the operation key for one minute, you can return to the running state by yourself

4. The alarm delay adjustment range is 0.1~3 seconds to prevent false alarms caused by on-site interference

5. Equipped with power up and power down detection functions, while cutting off alarm and shutdown output circuits, it can effectively suppress instrument false alarms

6. There is a current output terminal on the rear panel that is proportional to the oil level value of the fuel tank, for recording output

Used for measuring and indicating the oil level in the turbine oil tank,It can also be used for measuring other liquid levels. When the steam turbine rotates continuously at high speed, it needs to be equipped with a dedicated oil tank to continuously lubricate and conduct heat to its rotating components. Therefore, it is necessary to use an oil tank level monitoring device, coupled with an oil tank level sensor, to monitor the level of the oil tank. When the level is below a certain value, lubricating oil needs to be added to maintain the operation of the steam turbine to prevent accidents.
