Why Pressure Sensors are designed with stainless stell

There are many types of materials used for constructing pressure sensors in a variety of applications, but those made from stainless steel are considered the most reliable and durable.

High Tensile strength
In hydraulic applications where pressure overloads are commonplace a stainless steel pressure sensor can withstand a high number of pressure cycles without fatigue damage.

Durability and Hardness
In demanding environments a high reliability and durability is required to withstand the extremes of shock, vibration and temperature. An all stainless steel design is ideal for these applications due to its high toughness.

Corrosion Resistance
For the majority of fluids and gases, stainless steel provides excellent protection against short and long term corrosion due to a naturally occurring resistant surface layer formed by a self passivisation process.

Welded Seals
Over many pressure and temperature cycles an all welded mechanical assembly provides a high integrity pressure seal for very high pressure and vacuum measurement applications.

Cleanliness and High Purity
For food, beverage and pharmaceutical industries, stainless steel is the preferred material because of its high polished surface which makes it easy to clean and discourages bacterial growth during use. The other benefit is that all the mechanical piece parts exposed to the media can be made from one material and welded together so that there are no crevices to attract contaminants or process media residues.
