| Product Introduction
Independently developed and produced by winchen sensor, the WCLL300 series display-head submersible level sensor is an intelligent level instrument integrating level measurement, local display and signal transmission. It uses a high-accuracy diffused silicon core, and the probe is fully sealed in stainless steel and submerged in the liquid. The matching high-brightness LCD digital display head shows the current liquid level depth in real time, with no need for an external secondary instrument. This series supports multiple outputs such as 4-20mA, 0-5V and RS485, and the probe and display head can be installed in an integrated or split configuration. It is particularly suitable for water pools, deep wells, tanks and various level monitoring applications, making level measurement both simple and intuitive.
| Features
1. Flexible split installation: the probe is placed in the liquid and the display head can be wall-mounted or panel-mounted; the split installation solves the problem of long-distance observation in deep wells and underground pools;
2. High accuracy and high stability: uses an imported diffused silicon core, accuracy up to 0.5%FS, with built-in temperature compensation for long-term stability;
3. Anti-clogging and corrosion-resistant design: the probe is made of 304/316L stainless steel, effectively handling harsh media such as sewage, slurry and weak acids and alkalis;
4. Local high-definition display: comes standard with a high-brightness LCD display head that shows the level value, percentage and other information in real time, clearly visible day and night, with no need for a separate display instrument;
5. Fully sealed deep-water protection: integrated laser welding and double cable sealing give the probe an IP68 protection rating; it can be submerged in water up to one hundred meters deep for long periods with no signal leakage;
6. Multiple signal outputs: supports 4-20mA, 0-5V, RS485 and other outputs, and can be connected to PLC, HMI or the cloud to meet the needs of different control systems;
