Explosion-Proof Electronic Leak Point Sensor

💡 Key Summary: Explosion-Proof Electronic Leak Point Sensor – For Organic Solvents & Oils

YHSP-SA-Ex is an explosion-proof electronic leak point sensor designed to quickly detect organic solvent and oil (Oil) leaks on-site. Based on intrinsically safe explosion-proof certification (Ex ia IIC T6, KCs certified), it can be applied in hazardous areas including Zone 0. It features a selective detection structure designed to reduce nuisance alarms caused by water (rain, condensation, washdown water). In addition, the replaceable floor-sensor cartridge design helps reduce maintenance time and supports lower lifecycle cost. By improving detection reliability for early-stage leaks of solvents and oils, it strengthens overall safety management in critical facilities.

Selective detection for organic solvent & oil leaks, designed to reduce nuisance alarms

YHSP-SA-Ex: selective detection based on surface-tension technology

Designed to reduce nuisance alarms in water-exposed environments (rain, condensation, washdown). The YHSP-SA-Ex explosion-proof electronic leak point sensor selectively detects leaks of organic solvents and oils in hazardous areas to support rapid response and safe facility operation from the earliest stage of leakage.

CORE FUNCTIONS

🔬 Surface-Tension Based Selective Detection (Anti-Water Technology)

• Designed to reduce the impact of rain, humidity, and washdown water, while responding selectively to leaks of organic solvents and oils. Even around outdoor tanks or in humid environments, it helps reduce nuisance alarms and improve operational efficiency.

🔧 Replaceable Sensor Tip Design (Cost Saving)

• After a leak event, you do not need to replace the entire sensor. Simply replace the contaminated floor-sensor cartridge (sold separately) for quick recovery, reducing maintenance time and cost.

🛡️ Durability Optimized for Industrial Sites (High Durability)

• With impact resistance and noise-shielding design, it supports stable detection signals even in vibrating environments or where electrical interference may occur.

💡 Real-Time Self-Diagnosis (Self-Diagnosis)

• Works with the controller module to monitor cable breaks and sensor abnormalities in real time. If an issue is detected, it outputs an alarm immediately. Designed for 24/7 monitoring where no safety gaps are acceptable.

⚙️ Explosion-Proof Leak Detection System Configuration (System Configuration)

• Highest Level of Explosion-Proof Safety

Designed with intrinsically safe explosion protection (Ex ia), applicable to hazardous locations including Zone 0 where explosive gases may be continuously present. It is intended to support compliant and stable field operation.

• Required System Components

For compliance and safe operation, the system must be configured with a dedicated leak detection controller module, Zener barrier, and protective housing.
