Johnson Controls T-5502-1002 Temperature Indicator

The Johnson Controls T-5502-1002 is a professional-grade pneumatic temperature indicator engineered for technicians managing complex building automation systems. Designed for field-proven reliability, this 2.5-inch dial gauge provides a clear 0 to 100?F temperature range (with a secondary -17 to 37?C metric scale) to monitor HVAC discharge or return air. It operates on a standard 3 to 15 psig pressure range, translating pneumatic signals from transmitters into precise visual data. This unit features a 1/8" NPT air connection and is built for versatility, supporting both flush mount and surface mount configurations in control panels. As a direct replacement for 142-0316 and AKS-6244, it ensures seamless retrofitting in legacy Johnson Controls installations. The recalibration screw is easily accessible behind a removable clear plastic lens, allowing for field adjustments to maintain an accuracy of ? 3-2-3% of full scale across any commercial HVAC pneumatic control environment.

• Universal Compatibility: Serves as the precise Johnson Controls T-5502-1002 replacement for discontinued 142-0316 and AKS-6244 models.
• High Readability: Features a high-contrast white dial with black printing and a blue metric scale for fast, error-free monitoring.
• Dual Mounting Options: Includes "U" clamps with break-off notches for flexible flush or surface mounting in various panel thicknesses.
• Durable Construction: Finished in dull black lacquer to withstand standard mechanical room conditions and prevent glare.
• Precise Calibration: Equipped with an external recalibration screw for maintaining tight tolerances in pneumatic loops.

How do I calibrate the T-5502-1002?
The clear protective lens can be unscrewed, providing direct access to the recalibration screw on the dial face for field zeroing or span adjustments.

What is the standard air connection for this indicator?
This model uses a 1/8 inch NPT center-back air connection, consistent with standard pneumatic temperature indicator fittings.

Can this gauge be used in outdoor environments?
The unit is rated for an ambient temperature range of -20 to 150?F (-29 to 66?C), but it should be protected from direct weather exposure within a suitable enclosure.
