| Product Introduction
Developed and produced by winchen sensor, the WCLL300 series submersible level sensor (hydrostatic level gauge) is a fully sealed, submersible level measuring instrument. Based on the principle that liquid hydrostatic pressure is proportional to depth, it uses a highly stable diffused silicon pressure core to accurately convert the measured pressure into 4-20mA, 0-10V or RS485 standard signal output. The sensor uses a 304/316/316L stainless steel structure throughout and can be placed directly at the bottom of the liquid to achieve continuous level monitoring in water pools, deep wells, rivers, tanks and other locations. Its compact structure and extremely simple installation make it particularly suitable for locations where drilling holes is inconvenient or where a deep well already exists. It is widely used in water treatment, environmental protection, hydrology and other fields.
| Features
1. High accuracy and long-term stability: uses an imported diffused silicon core, accuracy up to 0.5%FS, 1%FS, annual stability better than 0.2%FS, low temperature drift.
2. Strong corrosion resistance and anti-clogging: the probe is made entirely of 304/316/316L stainless steel with a five-hole anti-clogging mesh, effectively resisting corrosion and clogging from sewage, slurry and weak acids and alkalis.
3. Fully sealed structure: integrated stainless steel laser welding, IP68 deep-water sealing, dedicated sealed cable connector; can be submerged in deep water for long periods without leakage.
4. Wide-temperature compensation: 0~80℃ wide-temperature compensation ensures accurate readings under day-night temperature differences and at different water depths.
5. Flexible and convenient remote transmission: standard two-wire 4-20mA, optionally with RS485 digital interface; long transmission distance, strong anti-interference, supports junction box adapters.
6. Minimal installation, maintenance-free: simply place the sensor into the liquid and secure the cable or bracket; no need to build a measuring well or complex mounting flange, with almost zero maintenance afterwards.
