Johnson Controls T-5500-1054 Indicator

The Johnson Controls T-5500-1054 Indicator is a professional-grade pneumatic temperature indicator designed for continuous visual monitoring in 3 to 15 psig transmission systems. Engineered for high-accuracy HVACR applications, this unit features a 3-1/2 inch dial with a -40 to 160 degree range, providing critical feedback on pneumatic transmitter performance. The high-contrast white dial face with black and blue scales ensures 1/2 % full-range accuracy, meeting rigorous ANSI Spec B40.1M standards. Built for versatility in the field, the T-5500-1054 supports both flush and surface mounting, equipped with notched U-clamps that stabilize the unit in panel thicknesses up to 3/4 inch. The 1/8 inch NPT air connection allows for seamless integration into existing pneumatic control systems. For technicians performing routine maintenance, the removable clear plastic lens facilitates quick cleaning and access to the internal recalibration screw, ensuring the HVAC temperature gauge remains calibrated to the specific transmitter range in use.

• High precision monitoring: Delivers ± 1/2 % of full-range accuracy for reliable diagnostics in complex pneumatic loops.
• Dual scaling: Features both Fahrenheit and Celsius scales printed directly on the dial for universal compatibility.
• Durable mounting options: Includes hardware for secure surface or flush-mount installation in various control panels.
• Field Serviceability: Designed with a screw-off lens for easy access to the recalibration screw without removing the entire indicator.
• Standardized fittings: Utilizes a common 1/8" NPT connection for fast replacement of legacy gauges.

• Can this indicator be used with any pneumatic transmitter? The dial range must exactly match the range of the transmitter (e.g., -40 to 160°F) to ensure accurate visual feedback of the 3-15 psig signal.
• Is this unit suitable for outdoor installation? While it has a wide operating range, the ambient temperature limits are -20 to 150°F; ensure the installation location stays within these parameters to prevent measurement drift.
• How do I calibrate the T-5500-1054? Calibration is performed via the adjustment screw on the dial face after removing the protective lens, referencing a known temperature and the corresponding transmission pressure.
