Application description

The pressure transmitter PPrecont® KS measures pressures from 0…1 bar up to 0…400 bar and converts it into a signal 4…20 mA resp. 0…10V or into a PNP switching signal (pnp – closer).

A thin-film strain gauge is used as pressure sensor. The small dimensions of the measurement sensor ensures a good behaviour against pulsating measuring media and vibrating installations as well as a very good reproduceability and hysteresis and an overload resistance of up to 4-times the measurement range. Due to the high natural frequency of the metallic membrane also fast pressure changings could be measured. The versions Precont® KS0 + KS1 has a process connection with an inside places separation membrane in high-grade steel in G1/2A or M20 x 1,5 acc. to DIN 16 288. This process connection is available in two version, with and without damping system.
The damping consists of an screw with a small slot that is placed at the medium side of the process connection. The variants Precont® KS 2, KS 3, KS 4 + KS 5 has a process connection with an front-flush separation membrane in high-grade steel in G 1/2A or M 20 x 1,5 for an seal in FPM or a metallic seal acc. to DIN 3852. The process connection is available with and without damping system. The damping consists of a choke that is placed at the measurement medium side. Ranges > 40 bar have an additional protection plate in front of the separation membrane. The version with damping should be used if an incompressible measurement medium with possible occuring pressure peaks over the measurement range should be measured. Pressure peaks can be produced e.g. by pumps, fast-closing vents, magnetic vents or controle cylinders. The pressure transmitter is conceived for advanced applications.
