Use of weld studs

Weld studs can be used instead of tensioning bands for the following types of
installation of the Clamp On measuring sensors.
The sensor distance (distance from the centre of the first stud to the centre of the
second stud) is determined by means of the "Sensor" Quick Setup (for devices with a
local display). Run the Quick Setup as explained on Page 72. The sensor distance is
displayed in the "Sensor distance" function (6886).
Note!
• The transmitter must have a local display and be installed and connected to the power
supply before you can run the "Sensor" Quick Setup.
• In the case of transmitters without a local display, the value can be determined as
explained on Page 63.
For an exact description of the sensor installation process, please refer to the
appropriate pages of the Clamp On versions. You must keep to same installation
sequence.
If you want to use a non-metric M6 ISO thread, please note the following:
• You require a sensor holder with a removable locking nut
(Order code: 93WAx – xBxxxxxxxxxx).
• Remove the preinstalled locking nut on the sensor holder with a metric ISO thread.
• Use a nut which matches your threaded stud.
