Thin Film Technology

In thin film sensor technology, a piezoresistive strain gauge bridge is deposited directly on the cell’s stainless-steel diaphragm which is in direct contact with the media being measured. With this technology, there is no transfer medium in between the media and sensing bridge measuring the pressure.

They can easily withstand dynamic pressures and extreme temperatures while providing the most accurate and reliable readings. Thin film sensors are especially suitable for harsh operational conditions such as pressure measurements in aerospace applications. 

As a rule, thin-film technology is only offered for relative pressure measurement, because creating a vacuum on the back of the membrane requires extensive effort constructionally.
