Use of weld studs for W / P sensors

Weld studs can be used instead of tensioning bands for the following types of
installation of the W / P Clamp On measuring sensors.
Note!
To determine the sensor distance (distance from the centre of the first stud to the centre
of the second bolt) use:
x the "Sensor Installation" Quick Setup menu if the measuring device has a local
operation. Use the Quick Setup as described on Page 82. The sensor distance is
displayed in the SENSOR DISTANCE function (6886). The transmitter has to be
installed and connected to the power supply to carry out the "Sensor Installation"
Quick Setup.
x the procedure described on Page 86 ff. if the measuring device has no local
operation.
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:
x You require a sensor holder with a removable locking nut
(Ordering code: 93WAx – xBxxxxxxxxxx).
x Remove the preinstalled locking nuts on the sensor holder with a metric ISO thread.
x Use a nut which matches your threaded stud.
