Exhaust Gas Temperature Indicator
This part number designates a panel-mounted engine Exhaust Gas Temperature (EGT) indicator. Manufactured by Ragen Data Systems or Insco (Model DST1939-1), this primary engine instrument is factory-installed on high-performance Cessna piston aircrafts.
Description
This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 10/20/2025.
Key Technical Capabilities
- Exhaust Gas Monitoring: Continuously processes electrical signals from engine-mounted thermocouples, converting thermal voltage shifts into direct, real-time temperature needle movement.
- Optimized Operational Limits: Features specialized faceplate scales (often including customized start, taxi, and operational green/yellow thresholds) to help pilots manage proper fuel-air mixture lean thresholds and monitor start parameters.
- Damped Jewel Linkages: Employs an internal design engineered to isolate the delicate pointer assembly from high-frequency powerplant harmonies, reducing needle jitter during extreme power changes.
- Integrated Multi-System Interfaces: Built with standardized rear pin connections designed to communicate seamlessly with existing engine clusters or centralized advisory displays without losing signal integrity.
