Johnson Controls T-5500-1053 Indicator

The Johnson Controls T-5500-1053 is a pneumatic temperature indicator designed for continuous visual monitoring in 3 to 15 psig pneumatic transmission systems. Featuring a 3.5-inch dial with a high-contrast white face and black printing, this gauge provides precise readings across a 50°F to 150°F range (dual scale with Celsius). The T-5500-1053 is the direct functional cross for KS-9047, ensuring seamless integration into existing control panels where legacy equipment requires replacement.

Built with internal dry filler and a removable clear plastic lens, this unit allows for easy access to the recalibration screw on the dial face to maintain an accuracy of ±0.5% of full range per ANSI Spec B40.1M. The casing is finished in durable black lacquer and supports flush or surface mounting. For panel installations, notched U-clamps are provided to accommodate thicknesses from 1/16 to 3/4 inches. The 1/8" NPT air connection ensures standard compatibility with most industrial HVAC and environmental control pneumatic lines.

• High Precision Accuracy: Rated at ±0.5% of full range to ensure reliable system monitoring.
• Direct Replacement: Serves as a standard functional cross for the KS-9047 temperature indicator.
• Dual Scale Readability: Displays both Fahrenheit and Celsius for versatile technical applications.
• Field Recalibratable: Removable lens provides direct access to the adjustment screw for ongoing calibration.
• Versatile Mounting: Includes hardware for both surface and flush-mount panel configurations.

What is the primary application for the T-5500-1053?
It is used in pneumatic control systems to provide a continuous visual read-out from a 3-15 psi transmitter, typically in HVAC or industrial automation environments.

Can this indicator be used in outdoor environments?
The unit has ambient temperature limits of -20°F to 150°F, but it should be protected from direct moisture and corrosive elements to maintain the integrity of the plastic lens and internal pneumatic components.

Does this unit require a specific air connection size?
Yes, it utilizes a standard 1/8 inch NPT female air connection, which is typical for Johnson Controls T-5500 series indicators.
