Type K extensions designed for EGT exhaust gas temperature and TIT turbine inlet temperature applications requiring higher temperature range capabilities.
Installation Hardware Applications
Weld Boss Installation: 7/16-20 thread specification weld boss requires proper welding procedures and exhaust system preparation. Boss installed in exhaust stack wall thickness with proper reinforcement and heat-affected zone considerations. Installation must maintain structural integrity of exhaust system while providing sealed mounting for temperature probes. Plug available for sealing unused boss locations during maintenance or when probe positions not required.
Bayonet Adapter Mounting: 3/8-24 thread bayonet adapter provides removable CHT probe installation in cylinder head spark plug ports. Proper torque specifications and copper gasket sealing essential for preventing combustion gas leakage and ensuring accurate temperature readings. Bayonet design enables probe removal for cylinder maintenance without disturbing permanent installations.
Selector Switch Configuration
Panel Integration: Universal selector switches require 2-1/4 inch panel cutout for standard instrument panel installation. Switches enable manual cylinder selection for single-gauge temperature monitoring systems where individual cylinder observation required during engine operation. Dual 4-section configuration allows simultaneous control of both CHT and EGT monitoring circuits in complex installations.
System Compatibility and Verification
Aftermarket Interface: JPI and Electronics International probe adapter enables connection of aftermarket monitoring instruments to existing Alcor temperature probes. Proper polarity verification essential during installation to maintain correct temperature indication. Resistance testing procedures confirm proper lead extension installation and electrical continuity through complete thermocouple circuit from probe to instrument panel gauge.
