Description
The PTiM18 monolithic 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 low cost, one piece monolithic construction is aimed at higher quantity OEM applications where single order quantities exceed the minimum batch size of 50 pieces and where price is a primary consideration. The manufacturing techniques employed ensure consistent batch performance, temperature stability and long term stability.
The compact 18mm diameter body design is suited to a wide range of applications including battery-powered, handheld devices where the PTiM18’s high 11kΩ ensures minimal current draw and maximum battery life.
To ensure that the PTiM18 monolithic 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.
