The AEM RTD-Type Temperature Sensor is a premium solution for high-accuracy temperature monitoring across a wide range of performance applications. Designed to handle extreme conditions, this closed-tip sensor offers consistent, reliable readings for exhaust gas temps (EGTs), cylinder head temps, air temps, coolant, intercooler, and fluid temps. Precision Meets DurabilityUnlike traditional thermocouples, AEM’s RTD sensor features a thin-film platinum sensing element for superior stability and accuracy. Its closed-tip design ensures extended durability and reduced restriction when installed in tight-flow areas. The Inconel-sheathed lead terminates in a high-quality DTM-style 2-pin connector for reliable connectivity under harsh motorsport conditions. Key Features Temperature range: -40 to 1,560°F (-40 to 850°C) Thin-film platinum RTD element: ±0.9% accuracy from 536°F to 1,560°F Closed-tip sensor head for improved longevity and minimal flow disruption 90° bent sensor tip for flexible installation in tight spaces Inconel tubing protects sensor wiring from heat and abrasion Includes M14x1.5 weld-in bung for easy and secure mounting No calibration required when used with AEM gauges or logging systems Applications Exhaust Gas Temperature (EGT) Cylinder Head Temperature (CHT) Pre- and post-intercooler charge temps Coolant, oil, or transmission fluid temps Brake rotor temperature in motorsport environments Why Choose RTD Over K-Type?RTD sensors provide greater long-term accuracy and reliability, especially under continuous high-heat cycles. They’re ideal for tuners and racers who need dependable data with minimal drift over time.
