EGT Probe Exhaust Gas Temperature Sensor - Compact Mini Size - 0.090" Diameter


• EGT-CM series
• Probe diameter 0.090 inch
• Enclosed Tip Sensing Junction (Foul Proof)
• Response time constant: 350 milliseconds
• Thread is M5x0.8 (Includes mounting nut)

(Recommended for fuel types: All)


The Miniature Exhaust Gas Temperature Sensor is specifically designed for use in a wide range of racing & testing applications. Made in the USA from superior materials. The Enclosed Tip sensing junction provides reliable measurements and maximum longevity.

The Exhaust Gas Temperature Probe is capable of surviving heat up to 2300 degrees F (1300 degrees C). The EGT probe will fit most internal combustion engine exhaust systems from approximately .750 inch diameter up to about 4 inch diameter with nominal installation modifications. The EGT probe is 0.090 inch" diameter (2.286 mm). The EGT probe cable lead length is 6 feet (1.8 meters).

The probe cable is over-braided in stainless steel for heavy-duty abrasion resistance. The signal wires are FEP insulated. Designed to deliver high performance, high temperature measurements, reliably and consistently.

These high temperature sensors are the choice for professional racing teams, R&D test labs, and enthusiasts. The EGT probe can be used for many different small engine applications, including Karts, Snowmobiles, Aviation, and Marine Racing.

IMPORTANT NOTE:  0.090" OD probes are not recommended for applications with high Exhaust Gas velocity or mounting pre-turbo (choose a 3/16" OD or 1/4" OD probe). Please confirm with your instrument manufacturer that the instrument is compatible with a Type K thermocouple sensor.
