THIN FILM SENSORS
Thin film sensors are precise, stable, diaphragm which is in direct contact with the

sensors. Most applications of thin film sensors between the media and sensing bridge
take advantage of their small size and the measuring the pressure. This eliminates the
options they provide engineers - their damaging expansion or shrinkage that can

Thin film sensors are more robust and less other transducers fail. They can easily withstand
