General Description
DLI is a loop powered digital indicator, which can be connected in
series with any 4-20mA current loop and will display the current flowing in meaningful engineering units. The large 3 ½ digit display is easy
to read and the whole device introduces a volt drop of less than 1V at
full scale, which means it can be used where several other devices are
already in the loop.
The Zero and span are adjustable so the indicator can be can be calibrated to display any range within the +/-1999 range, large positive
and negative zero offsets are easily accommodated. The DLI can be
housed in an extended H70 head with an window lid which allows a
transmitter and indicator to be conveniently mounted as a single unit.
The model is available as a ATEX approved II 1G EExia IIC T5 version.
Housings
The indicator can be supplied in an EEx de approved, IP68 enclosure in
a variety of materials to suit the needs of the environment in which it
is installed. Extended versions allow a transmitter and indicator to be
conveniently mounted as a single unit.
