Honeywell Analytics E3SRMH2 Remote Mounted Sensor

The Honeywell Analytics E3SRMH2 Remote Mounted Sensor is a critical component for technicians managing hydrogen gas detection in industrial and commercial facilities. Specifically engineered as the direct 1309A0059 cross-reference, this E3Point gas sensor provides high-accuracy monitoring of Hydrogen (H2) levels in environments prone to gas accumulation, such as battery charging rooms, laboratories, and mechanical spaces. Built with a rugged polycarbonate housing that resists corrosion, rust, and impacts, the E3SRMH2 is designed for long-term field reliability. It operates via a standard 4-20mA current loop and is fully compatible with RS-485 network protocols, including BACnet MS/TP and Modbus, allowing for seamless integration into existing building automation systems. By utilizing this remote-mounted configuration, contractors can extend the safety perimeter of an E3Point base unit, enabling dual-gas monitoring or wider coverage of large industrial areas without needing an entirely separate controller.

Key Benefits for HVACR Contractors:

• Enhanced Versatility: Direct replacement for 1309A0059, ensuring compatibility with legacy and modern Honeywell E3Point systems.
• Advanced Networking: Supports seamless integration with BACnet MS/TP and Modbus, simplifying data logging and remote system monitoring.
• Industrial Durability: The polycarbonate enclosure protects sensitive electronics against the harsh conditions common in mining and oil & gas applications.
• Precision Sensing: Utilizes a high-stability electrochemical cell for accurate Hydrogen gas monitoring with minimal cross-sensitivity.
• Flexible Installation: Remote mounting allows for optimal sensor placement in high-ceiling areas or tight locations where a full control unit is impractical.

Common Questions About the E3SRMH2:

Can the E3SRMH2 be used for dual-gas detection?
Yes, when paired with an E3Point standalone or network base unit, the E3SRMH2 functions as the secondary remote sensor, allowing a single installation point to monitor two different gas types simultaneously.

What are the wiring requirements for this remote sensor?
The unit typically integrates with the main controller via a 4-wire connection (two for power, two for communication) to maintain signal integrity over the 4-20mA or RS-485 loop.

Is this sensor suitable for outdoor use?
While the Honeywell Analytics E3SRMH2 is highly durable, it is primarily intended for indoor industrial environments and protected outdoor spaces like parking garages and loading docks.
