The Bio Diesel Exhaust Gas Temperature Sensor is specifically designed for use in Internal Combustion Engines operating on Diesel & Biodiesel or any system using a sulfuric or exhaust systems that are prone to fouling exposed junction EGT probes. This probe has been designed to withstand the rigors of marine and over the road trucking. It will also withstand the rigors of racing, tuning, and testing applications.

Made in the USA from superior materials, designed to withstand highly corrosive saltwater environments and even the most extreme racing conditions. The foul-proof sensing tip is recommended for EGT temperature measurements of sulfuric fuels such as diesel or bio diesel mixtures.

The Exhaust Gas Temperature Probe is capable of surviving extreme vibration and heat up to 2300°F (1300°C). The EGT probe will fit most diesel engine exhaust systems from approximately .750 inch diameter up to about 4 inch diameter with nominal installation modifications. The EGT probe is 0.187" diameter (4.75 mm) with a 90-degree bend to accommodate tight mounting locations. An adjustable (316 Stainless Steel) 1/8" NPT compression fitting adapter is included. 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 in the most extreme operating conditions.

The high temperature sensors of choice for professional racing teams, R&D test labs, and Enthusiasts. The EGT probes can be used for many different applications, including… but not limited to DHRA, Drag Racing, Diesel Sled Pulling, Road Courses, Tow Vehicles and Engine Management.
