General safety guidelines
IMPORTANT
Install in such as way as to ensure a totally reliable, uninterrupted power
supply to the controller. Too low a voltage supply can cause measuring
failures, which may result in dangerous overdosing within a control
system.
The CLT 1 sensor has a passive 4-20 mA two-wire interface. The power supply
is provided externally or by the controller. When the sensor is connected to
the DULCOMETER
are met automatically.
Additional safety guidelines, when using an alternative controller:
IMPORTANT
• If you intend to connect the sensor to devices other than ProMinent's,
• The power supply for the sensor must never fall below 16 V DC,
• The sensor is not electrically isolated. In order to avoid interfering
If using an alternative controller please note:
Power source: 16-24 V DC, min. 35 mA with 16 V DC
Max. load:
34
Slide the O-ring from below over the electrode shaft up to the clamping
ring. Leave a flat washer inside the DGM.
Insert the sensor in the DGM and screw on the plug until the O-ring seals.
The clamping ring determines the installation depth of the sensor.

even for a short period. The power supply must be able to bear a
minimum load of 35 mA at 16 V DC. Too low voltage supply can cause
measuring failures, which may result in dangerous overdosing within
a control system.
currents ensure potential isolation of sensor, power supply and other
devices connected to the measuring/evaluation instrument.
