💡 Key Summary: Electronic leak point sensor for organic solvents & oils, designed to reduce nuisance alarms in water/humidity environments

YHSP-SA is an electronic liquid leak point sensor engineered for fast on-site detection of organic solvent and oil leaks. It applies a selective detection structure based on surface-tension change, helping reduce unnecessary alarms that may occur in environments with water, rain, condensation, or washdown water. Maintenance efficiency is improved through a replaceable floor-sensor cartridge design, and when used with a dedicated controller module, it supports a reliable leak monitoring system.

💧 Electronic leak point sensor for organic solvents & oils, YHSP-SA

Selectively detects organic solvent and oil leaks to improve on-site safety management efficiency.

YHSP-SA is an electronic leak point sensor designed to reduce unnecessary reactions from common liquids such as water and selectively detect only organic solvent and oil leaks. It can be integrated with a dedicated controller module to build a leak monitoring system, making it ideal for improving safety standards and operational reliability.

KEY FEATURES

Key Features

🧪 Selective Detection Capability

• Designed to reduce nuisance alarms in water/humidity environments (condensation/washdown) and respond selectively to organic solvent and oil leaks.

⚡️ Ultra-Fast Detection Speed

• As soon as a leak contacts the bottom of the sensor, it outputs a detection signal based on the surface-tension change principle, supporting rapid response at the earliest stage of leakage.

🔧 Easy Maintenance

• The floor-sensor cartridge, a key component, is designed with a removable structure, allowing quick restoration by replacing only the cartridge when needed. (Floor-sensor cartridge sold separately)

💪 Excellent Durability

• Designed with impact resistance and electrical noise considerations to support stable operation across diverse indoor/outdoor environments.

🚨 System Self-Diagnostics

• When connected to the dedicated controller module, the system diagnoses not only leaks but also cable breaks and sensor damage in real time. If an abnormal condition occurs, it automatically generates an alarm signal so operators can respond immediately.

YHSP-SA is a practical solution that combines selective detection and maintenance efficiency for building an organic solvent & oil leak monitoring system.
