Assembly
WARNING
• Ensure that the axes of the sensor and pipe are per pen dicular to one another. Ensure
that the thread is aligned correctly. It will otherwise affect the stability of the measure-
ment points in pressurised processes.
• The axis through the hole of the sensor tip must line up with the pipe axis.
• The sensor tip must be covered by the water sample at all times during measurement.
• The measurement results will otherwise be incorrect.
IMPORTANT
If you later require measurement accuracy better than 10 %, fi t a tap near the sensor to
take water samples.
The sensor ICT 2 can be directly installed in tanks and pipes or via a fl ange and/or an in-line
probe housing.
Before installing the sensor, carry out commissioning up to and including zero point calibration.
Insert the sensor into the opening of the media tubing or the tank (the fl at seal must sit on the
inside of the tubing or tank). If used in fl owing media, the sensor tip bore must be placed in
the centre of the tube cross section.
Rotate the sensor so that the bore of the sensor tip is facing in the direction of the fl ow.
Tighten the union nut.

ICT 2 Inductive Conductivity Sensor, Electrical Installation
IMPORTANT
• Connect the sensor only when the mains power supply is switched off.
• Do not shorten the connection lead. The measurement result will otherwise be in cor-
rect. The warranty is void in this case.
• If using a DULCOMETER
®
D1C controller use a mains cable with earth lead! The sensor
cable screening must be earthed by the earth lead if there is potential inter ference!
• Install according to the relevant national directives.
Break open the large opening in the middle of the base of the DULCOMETER
®
D1C housing
(see Operating instructions DULCOMETER
®
D1C, part 1)
Screw in a 13.5 skintop connector (supplied with the DULCOMETER
®
D1C controller)
Cut off the brown and the yellow cable
Earth the total cable screen via the power lead of the mains cable of the DULCOMETER
®
D1C
controller if there is potential inter ference. For this purpose crimp e.g. a screen connector onto
the total screen.
Connect the sensor to the DULCOMETER
®
D1C controller in accordance with the terminal
connection diagram
Tighten the skintop connector until watertight, ensuring that there is still suffi cient cable inside
the DULCOMETER
®
D1C controller.
