Specifications

There are two contact types of float switches, NO contact and NC contact.
● NO Contact: The float switch sends a continuous signal when the oil level is high.
● NC Contact: The float switch sends a continuous signal when the oil level is low.
The float ball's specific gravity should be less than the oil's; otherwise, it cannot float. (The specific gravity of water is 1, and the specific gravity of general lubricants is between 0.85 and 0.90.)
When using oil with high viscosity, choose a large outer diameter of the float ball, so it can have greater buoyancy to overcome surface tension and have less misjudgment or malfunction when the level rises.
A magnet inside the float ball induces the reed switch by its movement. If the oil contains iron filings, it will result in misjudgment. Please make sure the oil is clean for precise detection.
