safety, driven by dedication, and delivering innovation.
YHSM-A01 is an All-in-One electronic leak point sensor that operates on DC 24 V without a separate control module. It provides chemical-family specific detection of organic solvents and oil-based chemicals, with no response to water. It detects leaks within 2 to 60 seconds, depending on the chemical. Integrated SSR alarm output (N/O) and RS-485 (YH-BUS) communication support equipment integration. The replaceable YHS-FS cartridge allows reuse of the sensor body and reduces maintenance costs.

๐ง All-in-One Organic Solvent & Oil Leak Detection Sensor | YHSM-A01
Optimized detection by chemical family with a built-in controller for fast on-site equipment integration.
YHSM-A01 is an All-in-One electronic leak point sensor for the organic solvent and oil chemical family. It integrates power input, alarm output and communication for standalone operation. It provides SSR alarm output (N/O) and RS-485 (YH-BUS) communication without a separate control module.
Core Technology of YHSM-A01 (Key Technology)
๐ก Smart All-in-One Design (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.
๐ฌ Optimized Detection by Chemical Family
โข Designed for chemical-family specific detection of organic solvents and oils without responding to water. Typical media include THF, acetone, IPA, toluene, MEK and xylene.
โก๏ธ Fast Detection & Response
โข Detects leaks within 2 to 60 seconds, depending on the chemical.
๐ง Replaceable Sensor Cartridge (YHS-FS)
โข Replace only the YHS-FS floor sensor cartridge if required and reuse the sensor body. This supports quick on-site replacement and reduced 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.
With its built-in controller, YHSM-A01 simplifies installation and supports efficient deployment of a chemical-family specific organic solvent & oil leak monitoring system.
