SD-A Static Charge Monitors: Advanced Electrostatic Safety Solution
SD-A Static Charge Monitors: Advanced Electrostatic Safety Solution
Introduction
The SD-A Static Charge Monitors is an innovative safety system designed to prevent electrostatic hazards in explosive environments like gas stations and oil terminals. Combining real-time monitoring with active discharge capabilities, this device significantly reduces fire and explosion risks caused by static electricity.
1. Core Functions
1.1 Real-Time Electrostatic Monitoring
• 360° Detection: Uses capacitive induction sensors to monitor static charges within a 2m radius.
• Precision Measurement: Ultrasonic ranging calculates target voltage (triggers alarm at ≥500V from 2m).
• Dynamic Alert System:
o Visual: Red LED flashes on detection.
o Audible: Voice prompts guide safe discharge.
1.2 Active Static Elimination
• Touch-Based Discharge: Users contact the Eliminator’s grounding ball for 3+ seconds.
• Verification: Voice confirms successful discharge ("You are safe").
1.3 Hazard Prevention
• Proactive Alarms: Warns before static reaches sparking thresholds.
• Zone Protection: Covers high-risk areas like fuel dispensers and vehicle lanes.
2. Key Features
2.1 Intelligent Design
• Modular Components: Separate Monitor and Eliminator units with wireless infrared communication (30° conical coverage).
• Auto-Calibration: Self-adjusts on startup; voice confirms readiness.
2.2 Safety-Centric Engineering
• Explosion-Proof: Certified ExibIICT4Gb (compliant with GB 3836.1/4).
• Durable Materials: Stainless steel housing and corrosion-resistant cables.
• Fail-Safes: Automatic shutdown at <10% battery
3. Technical Specifications
