7. Starting, operation
2. Hold the swivel female face seal with a suitable open-end wrench. Tighten the swivel
female face seal / swivel male face seal or mounting part (valve etc.) by a 1/8 or 1/4 turn
(depending on the sealing elements used) beyond the hand-tight position.
3. Please refer to the specific technical guides furnished by the fitting manufacturers for
additional specifications.
4. With that the transducer is mechanically connected. Electrical connection possibilities are
described in the following section.
Welding Connections (only WUC-10, WUC-15)
The weld needs to be fully penetrating, but amperage and heat need to be minimised. We
recommend flowing Argon gas through the transducer during welding. This will help to cool
the transducer. Prior to welding tubing to the transducer, it is recommended that a few test
welds be made.
Make sure the transducer is not connected to any other device, prior to arc
„
!
welding.
Disconnect the transducer from any electrical device.
„
Warning
The operator is responsible for the material compatibility as well as correct
„
handling, operation and maintenance.
Prepare the transducer for use
1. Adjust the zero point (please refer to chapter Zero Adjustment).
2. Verify integrity of the weld or seal by appropriate helium leak-testing procedures.
3. Turn the gas flow ON then OFF, 10 times to remove any particles generated during
installation. (The flow rate used should at least equal the process flow specifications.)
MSM, Modular Surface Mount (only WUC-16)
Please observe the corresponding technical specifications, such as torques and mounting
position of the contact components.
Electrical connection
Connect the enclosure to ground through the process connection, against
!
electromagnetic fields and electrostatic discharge.
