Key Technical Capabilities
    • Dual-Parameter Interface: Combines both Cylinder Head Temperature (CHT) and Exhaust Gas Temperature (EGT) tracking concurrently onto a single 2-inch display dial, optimizing limited panel real estate.
    • Thermal Stress Monitoring: Tracks vital temperature transitions across a clear degrees-Celsius faceplate scale, allowing pilots to prevent thermal shocking or overheating during high-power climbs and descents.
    • Electrical Sensor Processing: Engineered to receive stable analog inputs from engine-mounted thermocouples, translating tiny voltage variations into precise, real-time needle movements.
    • Damped Cluster Alignment: Employs internal jewel-bearing movement linkages designed to absorb constant engine vibration and cockpit harmonics, preventing pointer float during hard cruise segments.
