NGK / NTK RTA9000-EE090 / 91678 Post-DPF Exhaust Gas Temperature Sensor EGTSPerovskite ceramics sensing element allows wide range temperature detection up to 900°C. High heat resistance and flexible design of probe unable to install this sensor to exhaust pipe or catalyst casing. The sensor is designed to survive severe vibration or high temperature environment.Sensors optimized for two different temperature ranges: 100°C~900°C (C-type) and -40°C~900°C (E-type) Small element and thin probe for fast response Small size for low weight Robust one piece pressed metal tube Powder-filled element support for vibration resistance
