Description
The ELE-802L is a lightning-protected submersible level transmitter developed for long-term immersion and outdoor use. It adopts a high-precision diffused silicon sensor with a 316L stainless steel isolated diaphragm filled with silicone oil, ensuring accurate and stable pressure-to-level conversion.
An integrated lightning protection circuit effectively resists:
Electrostatic discharge (ESD)
Surge impact
Electrical fast transient/burst (EFT)
The transmitter features a 45° inclined pressure port design and 3 mm pressure inlet, reducing blockage risks and minimizing sudden pressure impact on the sensor. Combined with a 304 stainless steel housing and double-shielded purple copper cable, the ELE-802L delivers excellent durability, anti-interference performance, and long service life.

The EDPS series differential pressure switch is a special type of control switch. It is a kind of switch that controls closing or opening based on the pressure difference between mutual components and relies on electrical signals for information transmission.
Floats are available in 1–4 pieces (optional,or more), and the rod length can be customized.
Notes:Float switches cannot directly control solenoid valves, high-power relays, AC contactors, etc. A small relay HH45P is required for transition.
