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.

โจ 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
๐ก Smart All-in-One Design
โข 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.
๐ฏ Precise Selective Detection
โข 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.
โก๏ธ Ultra-Fast Detection & Response
โข 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.
โป๏ธ Easy Cleaning, Reusable Operation
โข Designed to allow reuse after cleaning if the sensor becomes contaminated, reducing maintenance burden. (Operate cleaning/reuse according to your site policy.)
๐ก๏ธ Strong Durability in Any Environment
โข 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.
