Magnetic Float Liquid Level Detection Switch for Lubrication Reservoirs

Running a lubrication pump without fluid can damage the pump and leave your machinery unprotected. The Magnetic Float Liquid Level Detection Switch is designed to be installed inside the oil or grease reservoir. As the lubricant is consumed and the level drops, the magnetic float lowers. Once it reaches a critical threshold, it activates a reed switch, sending a "low-level" warning signal so operators can refill the tank before the system runs dry.

Key Advantages & Benefits:

  • Fail-Safe Protection: Prevents air from entering the lubrication lines by ensuring the pump never runs completely empty.
  • Simple & Reliable: Uses a proven magnetic reed switch mechanism with no complex electronics to fail.
  • Chemical Resistance: Floats and stems are made from materials resistant to harsh industrial lubricants and additives.
  • Easy Retrofitting: Can be easily installed into existing standard lubrication reservoirs.

Versatile Applications:

  • Oil lubrication pump reservoirs
  • Coolant tanks
  • Hydraulic power units
  • Centralized grease tanks

Frequently Asked Questions (FAQ):

  • Q: How do I wire the level switch to a buzzer? A: The switch features a simple two-wire output that acts as a standard contact closure, which can be wired directly in series with a low-voltage warning buzzer or indicator light.
  • Q: Does it work with thick grease? A: For thick greases, we recommend our specialized follower-plate level switches, as standard floats may get stuck in high-viscosity non-leveling grease.

FAQ

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation


Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.


Process Validation Before Mass Manufacturing


Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.


Integrated Heating and Degassing Process


The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
