Les émetteurs de niveau submersibles adoptent des noyaux de pression piézorésistifs en silicium, offrant une précision 0.5 élevée. Submergés au fond des réservoirs, ils convertissent la pression hydrostatique liquide en signaux 4-20mA ou RS485. Avec des circuits anti-dérive et des câbles étanches, ils conviennent aux aqueducs, aux piscines chimiques et aux eaux usées pour une mesure continue du niveau de liquide.
Low-drift silicon sensing core: Oil-filled piezoresistive core features tiny thermal drift, delivering stable readings without offset during long underwater operation amid temperature shifts.
Fully sealed waterproof cable: Custom waterproof cables block liquid intrusion, resisting abrasion and corrosion to sustain uninterrupted signal transmission under permanent submersion.
Multi-layer circuit protection: Built-in surge and short-circuit guards shield internal circuits, preventing damage from unstable field power for steady long-term output.
Separated anti-clog diaphragm: Isolation diaphragm stops medium from touching the core; easy cleaning avoids clogging and maintains precise hydrostatic measurement for months.
Stable standard signal output: 4-20mA / RS485 signals have minimal transmission loss, retaining consistent data for long-distance continuous monitoring underwater.
Shock-resistant integrated housing: Vibration-proof structure withstands water turbulence, keeping internal components intact and reliable during prolonged submersion.
Dual waterproof & anti-corrosion cable design: Custom special waterproof cables with wear-resistant outer sheath effectively prevent liquid infiltration and medium corrosion, solving common cable leakage faults of generic submersible sensors during long-time underwater operation.
Complete multi-level electrical protection system: Integrated surge, short-circuit and isolation protection circuits guard internal amplifiers. It adapts unstable on-site power supply without signal failure or component burnout, boosting service life greatly.
Detachable anti-block pressure isolation diaphragm: The separating diaphragm avoids direct contact between sensitive core and sludge. Users only need simple regular cleaning to eliminate clogging errors, lowering daily maintenance frequency significantly.
Dual signal output compatibility: Supports both standard 4-20mA analog and RS485 Modbus digital signals, seamlessly connecting PLC, recorders and cloud monitoring systems to satisfy diversified industrial automatic control demands.
Strong anti-vibration compact industrial housing: Shock-proof internal fixing structure resists water flow impact and pipeline vibration. The whole unit maintains consistent measuring data even in turbulent sewage and river monitoring scenarios.
