Application
Thanks to its compact sizeand rugged construction with front end diaphragm, this miniature pressure transducer can be used anywhere. Made of stainless steel and hermetically sealed, it is particularly suitable for useunder harsh environmental conditions, for corrosive, viscous, liquid and gaseous media and for measurements on hydraulic systems in both damp and wet atmospheres. The high resonance frequencyof the transducer means that it can be used under the severest conditions e.g. in explosion tests and aerospace applications. It is very easy to install this transducer with no dead volume todistort the measurement result. A weldable coupler is available for these installation situations.

Description
The diaphragm, body and bayonet connector form a single unit in thisminiature pressure transducer. The thin diaphragm fabricated from a single piece with clamping ring, and the connector, are welded to the sensor body to provide a hermetic seal. Afour-legged film strain gauge bridge is applied to the rear diaphragm face, which is the sensor element of the transducer. Pressures are measured with respect to a sealed atmosphere ofapproximately 1 bar as reference pressure. The screw thread of the pressure transducer ends in an Oring groove, sealed by a rubber, plastic or metal O-ring according to the pressure range and medium.It is not permitted to have a seal directly against the front diaphragm. There is an O-ring inside the electrical plug-in connector. If a special watertight connector is used, the transducer can...
