Product Description

95% Aluminum Oxide Ceramic Insulator / Ceramic Rod For Oxygen Sensor

 

1. Description:

The Alumina ceramic insulatorfor oxygen sensor is a kind of material with high elasticity, corrosion resistance, wear resistance, resistance to impact and vibration. Ceramic’s good thermal stability and thick film high temperature sintering process make the ceramic pressure sensor’s operating temperature range up to -40 ~ 125 ℃. The ceramic's high elasticity and creep resistance make the ceramic pressure sensor have good long-term stability. Besides, the corrosion resistance character makes the sensor have unique advantages in the application such as the refrigeration, chemical and environmental protection and other fields.
