Four Cylinder EGT and CHT Combination Kit with Probes
The ECT204 is a full color EGT and CHT combination instrument that provides simultaneous, real-time display of all four cylinders. This kit includes four Type-K ungrounded, EGT thermocouple probes of your choice, four Type-J ungrounded, CHT thermocouple probes of your choice and , all connectors and installation hardware.
Both Cylinder head and Exhaust gas temperature functionality is TSO'd and meets the temperature accuracy requirements of SAE AS8005 for a Class IIa (+/- 1%) instrument. Functional displays include:
- Real-time four cylinder temperature display
- Menu select option for fast selection of display type
- Automated rich-of-peak (ROP) leaning function for EGT
- Automated lean-of-peak (LOP) leaning function for EGT
- Automated shock cooling monitoring for CHT
- Single cylinder temperature monitoring while retaining graphic indications for all cylinders (Both CHT and EGT simultaneously)
- Graphic trend analysis and viewing of all cylinders simultaneously (selectable for EGT or CHT)
The ECT204 kits are TSO'd and STC'd as a primary replacement instruments under all flight conditions (day/night VFR and IFR).
