Product Description

Film Alumina Pressure Sensor Ceramic / Ceramic Sensor Substrate

 

1. Description:

Alumina Ceramic (Al2O3) has excellent chemical corrosion resistance to many aggressive gases, solvents and acids. No additional protection is normally required to protect the sensor diaphragm from the measurement medium.High corrosion protection from acidic or alkaline solutions. These disc shaped pressure sensor elements are made from 96% pure alumina ceramic which unlike many metal based sensors, is chemically inert and therefore unaffected by most corrosive substances.

2. Feature Advantages:

1) High elasticity modulus

2) High compressive strength.

3) Anti corrosion

4) Abrasion resistance

5) Impact resistance

6) High precision

7) High stability

8) Good advanced ceramic materials

9) High welding sealing performance

10) High hardness and high density

11) Low thermal conductivity

12) Chemical inertness

13) Good wear resistance

14) High Fracture toughness

15) Good insulation performance

16) High temperature resistance

17) A variety of specifications is available

18) Satisfy various technical requests
