Description

The LFT3010 Anti-Sediment Level Transmitter features a fully sealed,submersible design.It integrates a pressure sensortested for long-term stability and reliability with a high-precision signal conditioning circuit,all housed in a stainless steelenclosure.
Key design highlights:fully welded housing with multi-layer sealing at all connection points(housing,cable,etc.);internallypotted electronics for extended service life;custom-designed removable filter ring that;prevents entanglement fromaquatic plants;resists clogging from sediment and particulates;is easy to disassemble,clean,and reuse.
This transmitter is ideal for long-term,stable level monitoring in environments with sediment accumulation and aquaticvegetation.
