YHSM-AR01 is an All-in-One electronic liquid leak point sensor that can be operated immediately by simply connecting power, without a separate controller module. It is designed to detect acids, alkali, and inorganic-solution leaks, and can deliver alarm signals by directly interfacing with equipment through an SSR contact output. By reducing installation components, it simplifies on-site deployment while providing the signal output/communication functions needed to build a reliable leak monitoring system.

✨ All-in-One Leak Sensor | YHSM-AR01
Built-in controller simplifies installation and enables fast equipment integration.
YHSM-AR01 is an All-in-One electronic leak point sensor designed for detecting leaks of acids, alkalis, and inorganic solutions. Without any external controller, it provides an immediate signal output via SSR (N/O), allowing you to build a safety system easily according to your site requirements.
Unique Selling Points of YHSM-AR01
💡 Smart All-in-One Design
• With a true All-in-One structure, no external controller or separate module is required, reducing wiring complexity and installation time. Designed for direct connection to on-site equipment.
🎯 Precise Selective Detection
• Designed for detecting leaks of acids, alkalis, and inorganic solutions. It helps reduce unnecessary reactions in water/humidity environments (condensation/washdown), and an optional water-detection function can be applied if required.
⚡️ Ultra-Fast Detection & Response
• Using the electrical reaction principle of the conductor at the sensor bottom, it detects leaks without delay and outputs an alarm signal immediately upon liquid contact.
♻️ Easy Cleaning, Reusable Operation
• Designed to allow reuse after cleaning if the sensor becomes contaminated, reducing maintenance burden. (Operate cleaning/reuse according to your site policy.)
🛡️ Strong Durability in Any Environment
• With a protective design considering external impact and electrical noise, it supports stable operation across factories, laboratories, and outdoor sites.
The built-in controller simplifies installation and enables quick deployment of a leak monitoring system for acids, alkalis, and inorganic solutions.
