YHSP-SAR-Ex is an explosion-proof electronic leak point sensor designed to quickly detect floor spills (leaks) of acids, alkalis, and inorganic solutions. It is certified with the intrinsically safe Ex rating (Ex ia IIC T6) for stable operation in hazardous areas. Its selective detection structure is designed not to react to water, reducing nuisance alarms in humid or washdown environments. The sensor is washable and reusable, lowering maintenance burden while improving safety reliability by capturing early-stage leaks.

Secure the โgolden timeโ for chemical incident response: an explosion-proof electronic leak point sensor
YHSP-SAR-Ex: selective detection, fast response, and intrinsically safe explosion protection to raise on-site safety standards.
In hazardous chemical facilities, the speed of detection often determines the scale of damage. Yoohantech YHSP-SAR-Ex is purpose-built for acids, alkalis, and inorganic solutions as an explosion-proof electronic leak point sensor. It detects even small leaks quickly in hazardous areas (Zone 0) to secure early response time and reduce secondary damage.
๐ Selective, High-Precision Detection (Selective Detection)
โข Designed to ignore rain, condensation, and washdown water while responding selectively to leaks of acids, alkalis, and inorganic solutions. This reduces nuisance alarms and improves operational reliability. (โป Water-detection option available depending on site conditions)
โก๏ธ Real-Time Ultra-Fast Response (Real-Time Response)
โข The sensor electrode reacts immediately upon leak contact and outputs a signal, helping prevent spread, corrosion, and equipment damage by securing early response time.
โป๏ธ Washable & Reusable (Reusable & Cost-Effective)
โข Unlike disposable consumables, the sensor is designed for repeated use after cleaning, lowering long-term operating and maintenance costs.
๐ก๏ธ Strong Chemical Resistance & Durability (High Durability)
โข Built with chemical-resistant materials (SUS304, PP, etc.) to deliver stable durability in harsh chemical environments.
๐ก Smart Self-Diagnostics (Smart Self-Check)
โข Works with the controller module to monitor cable breaks and sensor faults. If an abnormal condition is detected, it outputs an alarm immediately, reducing downtime and improving safety management efficiency.
โ๏ธ Safety System Configuration Guide (System Configuration)
โข Intrinsically Safe Ex ia Rating
The intrinsically safe explosion-proof design reduces spark risk, enabling safe installation and operation even in hazardous zones where explosive gases may be present.
โข Required Integration Components
This product must be configured with a dedicated leak detection controller module, explosion-proof Zener barrier, and protective housing. This ensures compliance with installation requirements and stable detection performance.
