Johnson Controls T-5210-1009 Transmitter

The Johnson Controls T-5210-1009 is a high-precision pneumatic temperature transmitter engineered to convert thermal measurements into a linear air pressure signal. Designed for integration with pneumatic receivers and controllers, this unit features a 0 to 100 degree operating temperature range and utilizes an 8-foot copper averaging element with a 1-foot capillary for accurate cross-sectional duct sensing. The 3 to 15 psig output pressure range is maintained via a 20 psig supply pressure, incorporating internal pneumatic feedback to ensure an exact proportional relationship between the sensed media and the transmitted signal. A ball-type control port and reinforced lever design enhance linearity and repeatable performance in demanding HVACR building automation environments. This direct-acting transmitter also includes an integral hypodermic needle test point for rapid field calibration and troubleshooting, requiring a 0.007-inch restricted supply for optimal 45 SCIM air consumption and flow capacity.

Key Benefits

• Accurate Averaging: The 8' copper element provides a reliable average temperature reading across large duct areas, preventing localized hot or cold spots from skewing BAS control logic.
• Linear Output: Internal pneumatic feedback and reinforced lever edges ensure high-linearity signal conversion across the entire 0-100°F span.
• Simplified Maintenance: Equipped with an integral test point, allowing technicians to verify output pressure without breaking the air lines.
• Robust Construction: Built for commercial pneumatic control systems with a bimetal element that compensates for ambient temperature variations at the transmitter head.

Common Questions

How do I calibrate the T-5210-1009 setpoint?
Calibration is achieved by using the internal adjusting screw. Technicians should monitor the output pressure at the hypodermic needle test port while comparing it to a known temperature at the averaging element to ensure it matches the 3-15 psig scale.

What air supply requirements are needed for this transmitter?
This model requires a clean, dry 20 psig supply pressure. To ensure stable operation and meet the 45 SCIM air consumption specification, a 0.007-inch restrictor must be installed in the supply line.

Can this unit be mounted in any orientation?
Yes, the T-5210-1009 is designed to operate in any position, provided it is secured to a rigid, flat mounting surface using the included sheet metal brackets.
