Johnson Controls T-5210-1007 Transmitter

The Johnson Controls T-5210-1007 is a high-accuracy pneumatic temperature transmitter designed for proportional control in commercial HVAC systems. This unit features an 8-foot copper averaging element paired with a 1-foot capillary, making it the standard for monitoring mixed air or discharge air temperatures where layering might occur. Operating on a 20 psig supply pressure, it produces a linear 3 to 15 psig output pressure signal corresponding to a 50 to 150 degree Fahrenheit operating range. With an air consumption rate of 45 SCIM, this transmitter ensures minimal bleed while maintaining high output flow capacity for responsive actuator positioning. The element is rated for temperatures up to 270 degrees, providing a robust buffer for high-limit scenarios. For technicians retrofitting legacy pneumatic loops, the T-5210-1007 offers reliable remote temperature sensing and straightforward calibration across the 100-degree span.

Key Benefits

• Averaging Accuracy: The 8-foot copper element eliminates "hot spots" in the duct by sensing the average temperature across the entire length.
• System Compatibility: Seamlessly integrates with standard 3-15 psi pneumatic control loops and receivers.
• Low Maintenance: High 45 SCIM flow capacity helps clear small contaminants and ensures rapid signal transmission to controllers.
• Durable Construction: Copper sensing element provides superior thermal conductivity and resistance to vibration in high-velocity air streams.

Common Questions

How do I calibrate the T-5210-1007 for my specific range?
Calibration is performed by adjusting the zero and span settings to ensure the 3-15 psig output aligns precisely with the 50-150°F scale using a precise pressure gauge and a known temperature reference.

Can this transmitter be used in steam coil applications?
While the element can withstand up to 270°F, it is optimized for HVAC duct temperature sensing; ensure the ambient temperature at the transmitter body remains within its rated functional limits.

Is the capillary length trimmable?
No. The copper capillary and averaging element contain a specific fluid charge. Cutting or kinking the line will depressurize the system and render the transmitter inoperable.
