Frequently Asked Questions
What is a planar ceramic heater for oxygen sensors? What are its main applications?
A planar ceramic heater for oxygen sensors is a high-performance heating component designed to provide quick ignition time, strong resistance to high temperatures and poisoning, and excellent high-temperature insulation (≥1MΩ at 800℃). It ensures the oxygen sensor reaches its operating temperature rapidly (light-off time ≤12s), which is essential for low pollutant emissions and fuel economy. Its main applications include:
– Automobile engine management systems and motorcycle exhaust after-treatment.
– Thermal surface igniters and hot air generation tools.
– Chemical analysis, laboratory equipment, and environmental monitoring systems.
What types of planar ceramic heaters are available? How do the conventional and XF pump current types differ?
Planar ceramic heaters are available in four main configurations: Conventional Switch Type, XF Pump Current Type, Air-Fuel Ratio Type, and Five-Wires Wide Range Type.
The main differences between the Conventional and XF Pump Current types lie in their electrical specifications:
– Operating Voltage: Conventional types operate at 1214V, while XF Pump Current types operate at a lower 79V.
– Heater Resistance: Conventional types feature a resistance of 9±1.5Ω, whereas XF types feature 3.0±0.5Ω.
– Response Time (300mV~600mV): At 800℃, the XF Pump Current type has a faster Poor-to-Rich response time (≤60ms) compared to the Conventional type (≤100ms). Both guarantee a long lifetime and high three-point bending strength (≥400MPa).
