Johnson Controls T-5210-1002 Temperature Transmitter

The Johnson Controls T-5210-1002 is a professional-grade pneumatic temperature transmitter designed for precision sensing in commercial HVAC control loops. Engineered for high-accuracy proportional control, this one-pipe pneumatic sensor converts temperature readings into a linear 3 to 15 psig output pressure range. It features a 5-1/2 inch capillary with bulb and is rated for an operating temperature range of 0 to 100°F, while the liquid-filled sensing element can withstand environmental extremes from -40 to 230°F. With a standard 20 psig supply pressure requirement and a 45 SCIM air consumption rate, this unit ensures reliable signal transmission to receivers or controllers. As the direct replacement for T-5220-1002, it fits seamlessly into existing pneumatic architectures. This transmitter is a critical component for technicians maintaining legacy systems where pneumatic HVAC controls require stable, drift-free calibration and rugged durability in mechanical room environments.

Key Benefits

• Precise Signal Output: Delivers a consistent 3 to 15 psig pneumatic signal for accurate temperature monitoring and control.
• Robust Sensing Element: The capillary temperature sensor handles element temperatures up to 230°F, preventing damage during system spikes.
• Efficient Air Usage: Optimized for a 45 SCIM air consumption and output flow capacity to maintain system pressure integrity.
• Field Reliability: Designed specifically for the demands of industrial and commercial pneumatic control cycles.

Common Questions

Can the T-5210-1002 be used in a two-pipe system?
This model is a one-pipe, non-relay transmitter. It requires an external restrictor in the supply line to function correctly within a pneumatic circuit.

What is the difference between this and the discontinued T-5220 series?
The T-5210-1002 is the contemporary technical successor to the T-5220-1002, maintaining identical performance specifications and mounting footprints for direct interchangeability.

Is the bulb suitable for immersion applications?
Yes, but for high-pressure fluid applications or pipes, it is standard practice to use a compatible thermowell to protect the capillary and bulb assembly.
