safety, driven by dedication, and delivering innovation.
YHSM-AR01 is an All-in-One electronic liquid leak point sensor that operates on DC 24 V without a separate control module. It provides chemical-family specific detection of acids, alkalis and inorganic solutions without responding to water. Response time is 2 to 60 seconds, depending on the chemical. Integrated SSR alarm output (N/O) and RS-485 (YH-BUS) communication support equipment integration. The all-in-one design simplifies installation and maintenance.

โจ All-in-One Leak Sensor | YHSM-AR01
Optimized detection by chemical family with a built-in controller for fast equipment integration.
YHSM-AR01 is an All-in-One electronic leak point sensor optimized for the acid, alkali, and inorganic solution chemical family. It operates without a separate control module and provides SSR alarm output (N/O) and RS-485 (YH-BUS) communication. The sensor does not respond to water and can be washed with water, dried and reused after detection.
Unique Selling Points of YHSM-AR01
๐ก Smart All-in-One Design
โข The all-in-one design integrates power input, alarm output and communication for standalone operation. It uses DC 24 V and requires no separate control module.
๐ฏ Optimized Detection by Chemical Family
โข Designed for chemical-family specific detection of acids, alkalis and inorganic solutions without responding to water. Typical media include sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, sodium hydroxide and hydrogen peroxide.
โก๏ธ Fast Detection & Response
โข Detects leaks within 2 to 60 seconds, depending on the chemical.
โป๏ธ Easy Cleaning, Reusable Operation
โข After detection, wash the sensor with water and dry it before reuse. The reusable design reduces replacement requirements and maintenance costs.
๐ก๏ธ RS-485 (YH-BUS) Communication
โข Provides an RS-485 (YH-BUS) communication interface for a host monitoring system (PLC / DCS / SCADA). Status indicators are RXD, TXD, POWER and LEAK.
The built-in controller simplifies installation and enables quick deployment of a chemical-family specific leak monitoring system for acids, alkalis, and inorganic solutions.
