Value Measurement

Level control system for limit value measurements The Per Level capacitive measuring systems are designed for limit value measurements of filling levels. The system comprises: models with fixed limit value switching points: Filling level probe KFS-5-... Evaluation electronics KFA-5-...

The fixed limit values are determined by means of the defined low-volumed measuring ranges. The limit value signals are practically independent of changes of the dielectric constant of the filling material. models with variable limit value switching points: Filling level probe KFS-4-... Evaluation electronics KFA-4-...

With this model, by means of adjustment, the limit value switching points can be moved over the complete large-volume measuring range. The position and the width of the variable area is the customers choice. These systems are an advantage for applications with regularly varying filling levels. Please note: DC-changes after the adjustment will lead to changes of the switching point. The probes KFS-5(4)-... are available from 100 mm up to 2000 mm in length. They are available with 1, 2, 3 or 4 fixed or variable switching points. The position of the fixed and the variable limit value switching points are user-definable within the possible area and therefore they can be determined for optimal matching of each application. The available evaluation units are: • • • • one point evaluation unit (KFA-5-1-.../KFA-4-1...) Two point evaluation unit (KFA-5-2-...) Four point evaluation unit Master (KFA-5-4-...) Extension possible with use of master/Slave systems. Extension of 4 measuring points per slave.

Compact Probes KFXAll specifications are subject to change without notice. (10/2008)

In addition, we offer compact-probes with process-connection-head KFx -... The evaluation electronic is integrated into the connection-head. Present variations available: • • KFx-5-... KFx-4-... with 1 or 2 fixed limit value switching points with 1 or 2 variable limit value switching points (mix of 1 fixed and 1 variable limit value switching point is also possible)

Process-connection with different adaptation possibilities: Process connection G1“ Triclamp Varivent Milk-tube-screwing For further information, please see the accessories chapter. For the possible model variations please see the type code.
