The heater rapidly elevates the temperature of the zirconia ceramic sensing element to its optimal operating range (typically 600-800°C) to ensure accurate measurement of oxygen concentration in exhaust gases, especially during cold engine starts.
Typical specifications include an operating voltage of 9-16 V DC (per ISO 16750-2), heating power of 12-18 W, and resistance at 25°C of 4.5-8.0 Ω. These are reference ranges; verify actual values for your specific model.
The heater uses electrical resistance heating with a platinum or ceramic element. With a heating power of 12-18 W, it can reach 600°C in ≤20 seconds, enabling closed-loop control during cold starts.
The heater is designed to meet ISO 16750-2 for electrical safety, including insulation resistance ≥10 MΩ at 500 V DC and dielectric strength ≥500 V AC for 1 minute. Always confirm compliance with the manufacturer.
