💡 Key Summary: All-in-One electronic leak point sensor for organic solvents & oils (built-in controller module)

YHSM-A01 is an All-in-One electronic leak point sensor that can be operated immediately by simply connecting power, without a separate controller module. It is designed to detect organic solvent and oil leaks, and features a selective detection structure that helps reduce unnecessary reactions in water and humidity environments (condensation/washdown). With an SSR contact output, it can directly interface with a beacon light or on-site equipment, allowing you to build a leak monitoring system easily based on your installation conditions.

For Organic Solvents & Oils | Built-in Controller (SSR/RS-485)

💧 All-in-One Organic Solvent & Oil Leak Detection Sensor | YHSM-A01

The built-in controller simplifies installation and supports fast integration with on-site equipment.

YHSM-A01 is a high-performance All-in-One electronic leak point sensor designed to detect organic solvent and oil leaks. Without any external controller module, it provides an immediate signal output via SSR (N/O), enabling simple field installation without complex wiring.

FEATURES

Core Technology of YHSM-A01 (Key Technology)

💡 Smart All-in-One Design (All-in-One Design)

• A true All-in-One design eliminates the need for a separate controller module, reducing installation components and simplifying system integration. Designed for direct connection to field equipment.

🔬 Selective Detection Design (Selective Detection)

• Designed to reduce nuisance alarms in water/humidity environments (condensation/washdown) and respond selectively to organic solvent and oil leaks, improving on-site operational efficiency.

⚡️ Fast Detection Based on Surface Tension

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

🔧 Replaceable Sensor Head (Replaceable Sensor Head)

• Even if the sensor bottom becomes contaminated or damaged, you can restore operation by removing/replacing only the floor-sensor cartridge. (※ Floor-sensor cartridge sold separately)

🛡️ Strong Durability & Stability

• Designed with physical impact and electrical noise considerations to support stable operation in indoor industrial environments.

With its built-in controller, YHSM-A01 simplifies installation and supports efficient deployment of an organic solvent & oil leak monitoring system.
