Description

Sensor Communication Interface Intrinsically Safe Package for Lower Explosive Limit (LEL) provides continuous monitoring in classified hazardous areas. Includes monitor, intrinsically safe barrier unit, and remote sensor mount for accurate detection and safe integration with facility systems.

The Sensor Communication Interface Intrinsically Safe Package for Lower Explosive Limit (LEL) is a comprehensive and reliable gas detection solution engineered to provide continuous, real-time monitoring of combustible gas concentrations in hazardous or classified environments. Specifically designed to meet intrinsic safety requirements, this package is ideal for facilities where explosive gas atmospheres may occur, ensuring both safety and regulatory compliance.

Key Features

• Intrinsically Safe Design This package includes an intrinsically safe barrier unit that restricts electrical energy within safe limits to prevent sparks or ignition in flammable atmospheres. This design enables safe operation in hazardous zones such as chemical plants, refineries, petrochemical facilities, and other industrial settings where explosive gases may be present.
• Continuous Combustible Gas Monitoring The system continuously measures combustible gas levels expressed as a percentage of the Lower Explosive Limit (LEL), enabling early detection of hazardous gas buildup before reaching dangerous concentrations. This feature is critical for preventing fire or explosion incidents.
• Remote Sensor Mount The remote sensor mount allows the sensor to be positioned close to the potential source of combustible gases such as near tanks, pipelines, or confined spaces while the main monitor remains in a secure, accessible location, enhancing safety and sensor accuracy.
• Advanced Communication Protocols Supports standard industrial communication protocols including:
  • Modbus RTU
  • 4–20 mA Analog Output
  • Dry Contact Relays
  These allow seamless integration with Building Management Systems (BMS), Programmable Logic Controllers (PLCs), alarm systems, and emergency shutdown controls, facilitating automated response actions and centralized monitoring.
• User-Friendly Interface with Configurable Alarms The monitor provides a clear digital display of LEL readings with user-configurable alarm thresholds, visual indicators, and audible alarms to alert personnel promptly when gas concentrations exceed safe limits.
• Modular SXP™ Sensor System Employs ChemDAQ's innovative SXP™ sensor cartridges, which are pre-calibrated and designed for quick, tool-free replacement, minimizing downtime and simplifying maintenance procedures.

The Sensor Communication Interface Intrinsically Safe Package for Lower Explosive Limit offers a dependable solution to detect flammable gas concentrations before they reach dangerous levels. Its intrinsically safe design makes it suitable for classified hazardous locations, providing peace of mind and regulatory compliance. The modular sensor system and remote mounting option allow for flexible installation tailored to your facility's unique safety needs. Whether monitoring tanks, pipelines, or confined spaces, this package ensures reliable detection and timely alerts to protect personnel and assets.
