💡 Key Summary: Electronic leak point sensor for acids, alkalis & inorganic solutions, designed to reduce nuisance alarms

YHSP-SAR is an electronic liquid leak point sensor that quickly detects floor leaks of acids, alkalis, and inorganic solutions. It is designed to reduce unnecessary alarms in water-exposed environments (rain, condensation, etc.), improving operational efficiency. With a structure that can be washed and reused, it helps reduce maintenance burden. When used with a dedicated controller module, it enables real-time monitoring of leak events, making it suitable for chemical spill prevention and building a reliable safety monitoring system.

For Acids, Alkalis & Inorganic Solutions | Controller Module Required

On-site monitoring solution to help prevent chemical incidents: electronic leak point sensor

YHSP-SAR: Selective detection technology for acids, alkalis & inorganic solutions.

YHSP-SAR is a professional electronic leak point sensor designed to detect even small floor leaks quickly and accurately. It focuses on acids, alkalis, and inorganic solutions, delivering an alarm signal at the earliest stage of leakage to support rapid response and improve safety for equipment, assets, and workplaces.

KEY FEATURES

Differentiated Technology (Key Features)

💧 Nuisance-Alarm Reduction Design

• Designed to reduce unnecessary reactions in typical water environments (rain, condensation, etc.) and respond selectively to leaks of acids, alkalis, and inorganic solutions. (※ Water-detection option can be added depending on site requirements)

⚡️ Real-Time Ultra-Fast Detection

• As soon as liquid enters the bottom area of the sensor, a specially designed conductor reacts, enabling real-time detection without missing even small leaks.

♻️ Washable & Reusable for Better Cost Efficiency

• No immediate disposal or replacement is required after leak detection. The sensor is designed for reuse after washing, helping reduce maintenance cost and improve operational efficiency.

🌐 Complete System Monitoring

• When integrated with a dedicated controller module, the system can monitor not only leak events but also cable breaks and sensor fault status in real time, improving system reliability.

💪 Durability Optimized for Industrial Sites

• Designed to diagnose leaks, cable breaks, and sensor damage in real time through controller-module integration. If an abnormal condition occurs, it automatically generates an alarm signal so operators can act immediately.
