1About this device
The measurement DULCOMETER®DMT for conductive conductivity is a two-
wire measurement transducer for use in all areas of process and process
technology in non-explosive areas.
It shows the electrolytic conductivity and/or specific resistance and produces
a proportional output signal.
An optimum PROFIBUS®-DP interface enables e.g. read out of the measure-
ment, correction and calibration values of the measurement transducer by a
PC or PLC and provides a superseding system.
PROFIBUS®-DP is a manufacturer-independent interface.
2Safety
2.1 Correct use
The DMT on-site measurement transducer is designed exclusively for the
•measurement of chlorine concentration
•measurement of temperature
•display of measured variables
•production of an output signal
•for the connection of DMT probes
It is prohibited to use the device for any other applications or to modify it in
any way!
Do not use the device out of doors without additional protection (protective
housing, weatherproof cover).
The DMT measurement transducer is not suitable for use in explosive areas.
2.2 Safety guidelines
CAUTION
•The device must not be used in a possible explosion area!
•The DMT must be operated by trained and authorised
personnel!
IMPORTANT
•The system must be suitably equipped and configured to
prevent overdosing of hazardous materials due to probe
failure.
•The DMT has no on/off switch. It starts to function as
soon as it is connected to a power supply.
3Storage and transport
Store and transport the DMT in the original packaging!
IMPORTANT
•Protect the DMT from damp and the effects of chemicals
even when packed!
Safety / Storage and transport
Page 8 ProMinent®
Ambient conditions for storage and transport:
Temperature: -20 °C to 70 °C
Humidity: max. 95 % relative humidity,
non condensing
4Assembly and installation
IMPORTANT
•The DMT is fully resistant to normal environments control
rooms.
•The DMT must be protected against rain and direct
sunlight!
Use a protective housing or weatherproof cover if in use
out of doors!
4.1 Assembly (mechanical)
The DMT can be wall, pipe or panel mounted.
4.1.1 Wall mounting
Mounting materials (included in delivery):
1 x wall/pipe bracket
2 x 5x45 mm round headed screws
2 x 5.3 washers
2 x 8 mm diameter plugs, plastic
1 x rubber insert
1 x locking screw (PT)
Wall mounting, please follow the steps below:
왘Remove wall/pipe bracket from DMT:
Pull the two snap fasteners outwards and push upwards (fig. 1, ➀).
Swing the wall/pipe bracket away from the DMT and pull downwards
(fig. 1, ➁).
왘Mark two drill holes diagonally opposite one another using the mounting
bracket as a template.
왘Drill the holes: Ø 8 mm, depth = 50 mm.
왘Screw the wall/pipe bracket in place inserting the washers (fig. 2).
왘If the DMT is also to be secured with a screw, pierce the screw hole in the
back of the housing (housing must be open) and attach a rubber insert
(fig. 2, ➀) to the bracket.
왘Hang the DMT onto the top of the bracket (fig. 3, ➀) and push down
gently against the bracket (fig. 3, ➁); then push upwards until you hear a
click (fig. 3, ➂).
왘Tighten the locking screw to secure more firmly (housing is open).

4.1.2 Pipe mounting
Mounting material (included in delivery):
1 x wall/pipe bracket
2 x cable ties
1 x sealing cap
1 x locking screw (PT)
Can be mounted onto pipes of diameters from 25 mm to 60 mm.
ProMinent®
Page 10
Pipe mounting, please follow the steps below:
왘Remove wall/pipe bracket from DMT:
Pull the two snap fasteners outwards and push upwards (fig. 1, ➀).
Swing the wall/pipe bracket away from the DMT and pull downwards
(fig. 1, ➁).
왘Fasten the bracket to the pipe using the cable ties (or pipe clamps)
(fig. 3).
왘If the DMT is also to be secured with a screw, pierce the screw hole in the
back of the housing (housing must be open) and attach a rubber insert
(fig. 2, ➀) to the bracket.
왘Hang the DMT onto the top of the bracket (fig. 3, ➀) and push down
gently against the bracket (fig. 3, ➁); then push upwards until you hear a
click (fig. 3, ➂).
왘Tighten the locking screw to secure more firmly (housing is open).
4.1.3 Panel mounting
IMPORTANT
•The control panel must be thick enough not to buckle
once installed. (To achieve enclosure rating IP 54, steel
must be at least 2 mm thick; plastic should be
correspondingly thicker.)
NOTE
The DMT will protrude from the control panel approx. 30 mm
once mounted.
