Functions include correct area with closure of up to 8 spray boom sections,
alarm functions for dosage and minimum tank contents and possibility for
audio/visual alarm.
The transducers utilised are chosen for long service life and good signal quality.
Speed, area switch and revolutions transducer is the same component. The
flow transducer has a diode built into the housing to aid servicing. As the rotor
turns, the diode will flash thereby indicating it functions.
The system has a non-volatile memory with no battery which simplifies stor-
age. All parameters in the menus are saved in the display’s memory and are
not lost when the power is disconnected.
The materials and electronics for the components have been developed to last
many years under agricultural conditions.
Options include a 4-20 mA transducer (e.g. pressure), revolutions transducer,
area meter transducer and switch box for boom sections when used with BK or
BK/EC control unit (only for HM 1500).
