Description
The PTi18 pressure sensors are made with a ceramic Al2O3 base plate and a flush diaphragm, and operates using the piezoresistive principle.
The Wheatstone bridge is screen-printed on one side of the flush ceramic diaphragm which is, in turn, glued to the base plate. The bridge faces the inside where a cavity is made and the diaphragm’s opposite side can therefore be exposed directly to the medium to be measured. Because of the Al2O3 ceramic excellent chemical resistance to aggressive gases, most of solvents and acids, etc, no additional protection is normally required.
The PTi18 ceramic pressure sensor capsule is intended for use by OEM manufacturers of machines and equipment where the integration of pressure sensing or monitoring is required.
The compact 18mm diameter body design is suited to a wide range of applications including battery-powered, handheld devices where the PTi18’s high 11kΩ ensures minimal current draw and maximum battery life.
To ensure that the PTi18 ceramic pressure sensor capsule meets its specification when installed, it is essential to ensure that it is mounted correctly. We will provide all the information required including engineering drawings to ensure successful incorporation into your product.
