Pyrometer Ext. Module for Incandescent Light

The Pyrometer Extension Module for Incandescent Light by AutoMeter (SKU ATM5256) is a specialized instrument designed for serious performance builders and diesel technicians who need real-time exhaust gas temperature monitoring beyond standard gauge capabilities. This extension module expands the functionality of compatible AutoMeter pyrometer systems, allowing installers to position temperature sensing capabilities where space constraints or wiring runs would otherwise limit placement. Whether you're tuning a high-output diesel engine, monitoring turbocharger health on a modified gasoline build, or validating air-fuel ratios under load, this module bridges the gap between gauge location and sensor placement.

Built to AutoMeter's proven standards, the Pyrometer Extension Module operates with an incandescent light display system, delivering accurate thermal readings with minimal signal degradation across extended cable runs. The compact form factor—measuring 5.25 x 4.6 x 5.35 inches and weighing just 0.42 lbs—integrates cleanly into engine bays where dashboard real estate or firewall routing complications demand flexible sensor management. This module maintains the integrity of factory gauge circuits while allowing aftermarket sensors to feed data reliably, making it ideal for retrofit installations on turbocharged, supercharged, or naturally aspirated engines undergoing performance upgrades.

Mechanics and engine builders benefit most from this extension module when upgrading or troubleshooting pyrometer installations on Cummins, Duramax, Powerstroke, and other high-heat applications where EGT management is critical to longevity and power output. Installation pairs directly with compatible AutoMeter gauge faces and wiring harnesses; verify your existing pyrometer model against AutoMeter specifications before ordering to ensure seamless integration. The module's modular design means you can expand sensor capability without complete harness replacement—a practical solution for diagnostic shops, performance tuners, and fleet maintenance operations managing mixed gauge configurations.
