Infrared clutch temperature sensor for contact free temperature measurement of the clutch plates. Utilizes a remote mounted amplifier away from the heat source where the lens is mounted. This separates the amplifier from the rapid rates of temperature change. The cable distance between the lens and the amplifier can be user defined from 100 to 750 mm when ordered. Proven in F1 for over 5 years and used by all major manufacturers. The INF-CLT-500 infrared clutch temperature sensor version has a non-linear output signal and measures between 0 to 500°C. We can offer the lens housing in two versions, 11mm cylinder or cylinder with mounting flange.
