4. Applications
The electronic module type KDSE is a transmitter with integrated magneto electric measuring element for
measurement of floater’s actual position or and transmission of actual pointer position into an electrical signal.
The electronic module must be assembled in an enclosure possessing a minimum degree of protection of IP20
(EPL Gb) resp. IP54 (EPL Db). This enclosure and the connector should by sufficient for the applied (EPL).
5. Operational mode and system design
The electronic transmitter type "KDSE" is used to convert the pointer position of the mechanical measuring
system into a proportional 4-20mA signal.
The electronic module type KDSE is a "magneto-electrical angle sensor" used for recording the position or the
angular position of a magnet in the variable area flow meters series KDS and BGK. Either the position of the
float, in which there is a permanent magnet, or the angular position of a ring magnet, which is located on a
magnet tracking system, is detected directly. With the latter, the angular position of the axis with the follower
magnet serves as a measurement interface between the mechanical part and the electronics
The microprocessor controlled KDSE transmitter is used in flowmeters series KDS and BGK. The position of the
float is transmitted to the pointer axle by means of a magnetic system. The KDSE measures the field of a mag-
net mounted on the pointers axle and generates an output current of 4 to 20 mA from it.
The scale is generally non-linear and is linearized in the process with a minimum of 16 interpolation points. This
points and the measuring range is defined by manufacturer while calibrating the complete instrument.
The earth’ magnetic field and moderate homogeneous external magnetic fields are largely compensated.
