Johnson Controls T-5210-1150 Transmitter

The Johnson Controls T-5210-1150 Transmitter is a precision-engineered pneumatic temperature transmitter designed for high-accuracy sensing in commercial HVAC systems. This duct-mounted transmitter features an 8-foot copper averaging element paired with a 1-foot copper capillary, specifically designed to mitigate the effects of stratified air and provide a true average temperature reading across large duct cross-sections. This unit operates within a 20 to 120 degree F operating range, converting thermal input into a proportional 3 to 15 psig output signal via an exact pneumatic feedback mechanism. Internal construction includes a ball-type control port for high sensitivity and a reinforced lever for enhanced linearity. To ensure long-term stability, it incorporates a bimetal element for ambient temperature compensation and an integral hypodermic needle test point for rapid field calibration checks. High-efficiency operation is maintained with a 45 SCIM air consumption rate at a standard 20 psig supply pressure.

Key Benefits:

• True Averaging Sensing: The 8-foot copper element ensures accurate temperature measurement by averaging variations across the duct.
• Enhanced Linearity: Reinforced lever edges and a specialized bimetal element provide a stable and predictable 3-15 psig output.
• Streamlined Diagnostics: Features an integrated test port for "no-leak" pressure readings during routine maintenance and system balancing.
• Industrial Durability: Rugged copper construction of the element and capillary ensures longevity in demanding air handling environments.

Common Questions:

What is the proper orifice size for the air supply?
This transmitter requires a .007-inch restricted supply for optimal performance and accurate signal transmission.

Can the T-5210-1150 be used for dew point applications?
Yes, when used in conjunction with a locally purchased Dewcel sensor, these pneumatic transmitters can function as dew point transmitters.

How do I handle the averaging element for installation?
Contractors should use the included sheet metal brackets for surface mounting and ensure the element is distributed evenly across the airflow path for precise duct temperature measurement.
