Dwyer TE-DFG-F0644-00 Duct Temperature Sensor | Official Distributor DLK Vietnam

In modern HVAC systems, precise control of airflow temperature is critical to maintaining operational efficiency and energy savings. A standout device trusted by engineers is the Dwyer TE-DFG-F0644-00 duct temperature sensor, developed by the renowned measurement brand Dwyer Instruments (USA) and officially distributed by DLK Vietnam.

1. Role of Duct Temperature Sensors in HVAC Systems

In centralized air conditioning (HVAC) systems, duct temperature sensors serve the following purposes:

• Monitor supply and return air temperature inside the ductwork
• Control the operation of heat exchangers, dampers, fans, and chillers to maintain temperature stability
• Optimize cooling/heating performance, reducing electricity consumption
• Support BMS (Building Management Systems) with operational data and early warning of deviations

Thanks to its precise measurement and fast response, the TE-DFG-F0644-00 is an ideal choice for commercial buildings, factories, data centers, and areas requiring strict temperature control.

2. Key Features of TE-DFG-F0644-00

The Dwyer TE-DFG-F0644-00 duct temperature sensor is optimized for industrial environments and modern buildings, offering several outstanding advantages:

• High Accuracy: Uses RTD or thermistor (optional) for extremely low error margins, ensuring stable measurement signals
• Probe-Type Design: Insert-style probe for direct airflow measurement inside ducts
• IP65-Rated Housing: Dust- and moisture-resistant, suitable for harsh environments
• Flexible Output Options: 0–10V, 4–20mA, or raw sensor signal – compatible with most BMS platforms
• High Mechanical Durability: Aluminum alloy housing and stainless steel probe for long service life
• Easy Maintenance: Modular design allows for quick disassembly and convenient inspection or replacement

These features make the TE-DFG-F0644-00 an effective tool for stable and accurate temperature monitoring, ensuring optimal HVAC system performance.

3. Real-World Applications in Projects and BMS Systems

The TE-DFG-F0644-00 is widely used in:

• Central HVAC systems in high-rise buildings, offices, and hotels
• Manufacturing plants, industrial workshops, large ventilated warehouses
• Data centers, server rooms – where continuous temperature monitoring is critical
• AHU, FCU, and chiller plants in intelligent building management solutions (BMS)

The sensor operates reliably across a wide temperature range and delivers precise signals to central controllers, ensuring smooth system operation and preventing overheating or temperature imbalance.
