Inductive sensors for high pressure applications are manufactured using two technologies.
The classic construction with a ceramic pressure plate allows pressures of up to 500 bar. It is the most widely used technology for high pressure resistant inductive sensors.
For particularly demanding applications, inductive sensors are alternatively manufactured with an extremely resistant, full metal housing, including the sensors sensing face. Their housing is made from a solid piece of stainless steel which is suitable to resist pressure of use up to 1000 bar | 14500 psi.
