Use of weld bolts 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:
• the "Sensor Installation" Quick Setup menu if the measuring device has a local operation. Use the
Quick Setup as described on Page 64. The sensor distance is displayed in the SENSOR DISTANCE
function. The transmitter has to be installed and connected to the power supply to carry out the
"Sensor Installation" Quick Setup.
• the procedure described on Page 67 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:
• You require a sensor holder with a removable locking nut.
(Ordering code: 90WAx – xBxxxxxxxxxx)
• Remove the preinstalled locking nut on the sensor holder with a metric ISO thread.
• Use a nut which matches your threaded bolt.
