Product Description

Film Alumina Pressure Sensor Ceramic / Ceramic Sensor

 

1. Description:

Industry professionals employ pressure sensors in a variety of applications, ranging from aerospace to oil and gas to utilities. In many cases, they are subjected to harsh operating and environmental conditions, such as high pressures, corrosive compounds, and temperature extremes. For use in these circumstances, ceramic pressure sensors are a suitable option.

 

Pressure sensors are often employed to handle extreme conditions such as high pressures, corrosive atmospheres, and high temperature processes. Ceramic pressure sensors are an ideal alternative to conventional oil-filled pressure sensors under such circumstances.

 

Because of their unique construction and ceramic’s chemically inert nature, ceramic pressure sensors can withstand harsh atmospheric conditions without sacrificing performance. Robust, reliable, and washable, they are a durable and cost-effective solution to a variety of demanding applications.

 

2. Feature Advantages:

Ceramic pressure sensors have many advantages over traditional stainless steel counterparts. Perhaps most importantly, they are significantly stronger than oil-filled diaphragms. Similarly, they can withstand high operating temperatures and pressures without losing sensitivity at low pressure values. They tolerate relatively high over pressures as well.
