SISCO capacitive level sensor for corrosive/high-temperature liquids is designed for reliable liquid level measurement in demanding industrial environments. With a measuring range of 1-1500 mm, pressure resistance from 0 MPa to 30 MPa, and accuracy up to 0.5% FS, it provides stable and precise level monitoring. The IP67-rated housing ensures excellent protection against dust and water, while the compact 300g design makes installation easier in various process applications.
Robust Hardware & Construction for Tank Level Monitoring
- Corrosion-resistant build with flexible extension: This capacitive level sensor uses PFA, PTFE, and 316L stainless steel for wetted components, perfectly suited for corrosive and high-temperature liquids. Rod-type probe supports up to 5 m length; cable‑type probe can reach 25 m to fit deep tanks.
- Zero measurement dead zone: No blind measuring distance, enabling reliable liquid level measurement for all kinds of storage tanks and vessels. Accurate level transmission even at low liquid levels inside the tank.
Superior Measuring Performance & Adjustable Parameters
- High-precision level detection: Adopting the capacitive principle for liquid level measurement, it delivers mm-level accuracy to capture subtle liquid‑level changes for continuous tank monitoring.
- Configurable digital filtering for stable output: Built‑in digital filtering program with adjustable damping time ensures smooth and stable level readings. Calibrated zero-point and measuring range parameters can be modified on-site to match your working conditions.
Applications
Built to meet varied user measurement demands, this capacitive level sensor performs stable liquid-level monitoring for numerous industrial applications. It is widely deployed in the food industry, metallurgy, petroleum, and chemical sectors, offering dependable level detection for ordinary liquids as well as corrosive and high-temperature liquids.
