Instruction Manual
DM08
Special safety instructions:
Danger! Electric current!
Particular care must be taken if the front window of the housing becomes fogged over or discol-
oured because moisture, water or product might seep through the wire sheath into the terminal
compartment in the housing!
Ingress protection IP67 is only achieved if suitable and tightly screwed down cable glands or
conduits are used. If the cable glands are only tightened manually water may leak into the ter-
minal compartment in the housing.
Electromagnetic compatibility is only achieved if the electronics housing is closed. Leaving the
enclosure open can lead to electromagnetic disturbances.
Further warnings that are specifically relevant to individual operating procedures or activities can
be found at the beginning of the relevant sections of this operating manual.
4 Construction and function
4.1
Construction
The DM08 comprises a sensor and the display electronics. The sensor is used to measure fluid
media. The display electrodes generate the coil current required for the magnetic field and pre-
pares the induced voltage applied to the electrodes.
The DM08 does not need any moving parts to make measurements. The inside of the measuring
tube is completely open, allowing the fluid to flow unhindered through the measuring tube.
Display electronics:
The display electronics has a backlit LCD.
6 buttons are used for operation. That facilitates easy configuration of the display electronics.
Furthermore the display electronics has an analogue 0/4 … 20 mA current output, a pulse or fre-
quency output and a status output.
