Notes regarding the function
The main problem with pressure-proof inductive proximity
switches is the thick coverage of the active surface (generally
from a ceramic material) required to obtain the pressure
resistance. The thickness of this coverage must be deducted
from the normal usable sensing range of the device,
with the result that just a small or even no usable sensing
range remains. In the market devices are available, which
come with the oscillator coil mounted on the high-pressure
side. It is inevitable that this type of proximity switches poses
reliability problems when used in an environment of
standard applications like hydraulic oil, high temperatures
or alternating pressure loads.
The ipf electronic pressure-proof sensors have all their electronic
components, including ferrite core and coil, on the
pressureless side. The remaining usable sensing range is
more than sufficient.The sensor has a very high mechanical
resistance and an outstanding impermeability, as the sturdy
robust ceramic plate is shrink fitted into the stainless steel
housing.
The very large sensing range allows the use of a simple, robust
ceramic plate with sufficient thickness on the front face.
These devices are best suited for applications with a high dynamic
stress in compression.
