• Read this document before setting up the product and keep it during the entire service life.

• The product must be suitable for the corresponding applications and environmental conditions without any restrictions.

• Only use the product for its intended purpose (→ Intended use).

• Only use the product for permissible media.

• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur.

• The manufacturer assumes no liability or warranty for any consequences caused by tampering with the product or incorrect use by the operator.

• Installation, set-up, operation and maintenance of the product must be carried out by personnel qualified and authorised for the respective activity.

• Protect the product against damage.4 3 Intended use The welding adapter allows the installation of sensors in tanks or piping systems.

If the tank or pipe system is treated after the adapter has been welded in (e.g. grinding, pickling, sand-blasting, glass bead blasting or applying procedures such as powder coating, painting etc.):

• Make sure that the inside and sealing area of the adapter are clean and not damaged. Appropriate measure: using the welding aid (→ 4.1).

• The welding operation must be carried out by authorised personnel.

• The welding operation must be carried out carefully and according to state-of-the-art technology.

• During welding and the following cooling phase the sensor must not be in place.

• The surfaces must be free from any contamination.

• Welding materials must be suitable for the adapter and wall material. ► The requirements in the specifications, of common practice, in regulations, norms, of intended use and the application must be applied. > They determine the welding procedure, the welding material, the connection category and connection type, including chamfer, welding penetration depth and demands on the surface. 4 Installation CAUTION! During the welding operation, the adapter and the welding aid can increase in temperature to over 65 °C (149 °F). > Risk of burns. ► Let the adapter and the welding aid cool down.5

4.1 Welding operation with welding aid

The basic notes and guidelines must be adhered to (→ 3.1).

• The welding method must be suitable for the welding task and the power of the welding equipment must be adapted to the material thickness.

• The adapter must not warp.

• During welding, avoid overheating of the adapter and observe sufficient cooling phases.

• The sealing area of the adapter must not be damaged by weld spatter or similar. The sealing area should be sufficiently protected before starting the welding process (→ 3.1). ► Bore a hole in the pipe or tank wall with the outside diameter of the adapter. ► Basic notes (→ 3.1). ► Insert welding aid E30508 (for heat conduction and protection of the sealing edge) and tighten by hand. Welding adapter (1) with mounted welding aid (2):

Please take into account the required space when using a connection cable with an angled socket. For this purpose, align the adapter prior to the welding operation to determine the end position of the electrical sensor connection. ► Screw the sensor into the adapter with the specified tightening torque (→ Operating instructions of the sensor). ► Connect the connection cable to the sensor. ► Align the unit. ► Mark the alignment at the welding adapter and the pipe/tank. ► Remove the sensor from the adapter. ► Carry out the welding operation. The positioning may change when the sensor is removed and then the original orientation is not guaranteed. ► Fix the adapter in several spots with a sufficient adhesive force. Apply the fixing points at equal distance opposite each other. ► Apply the welding seams between the fixing points opposite each other. ► Ensure sufficient intervals between the individual sections to avoid glowing through or warping of the adapter due to overheating.7

► If possible: weld the inside. ► Let the adapter and the welding aid cool down. ► Remove the welding aid. ► Remove deposits from the adapter thread. ► Screw in the sensor by hand in order to check for dimensional accuracy and functionality of the thread. If the tightening torque is too high, do not use any tool, but check the thread and replace the adapter, if necessary. 5 Mount sensor A lubricating paste is required to install the sensor. It must be suitable and approved for the given application and compatible with the elastomers used (e.g. seal). ► Ensure cleanliness of the sealing areas. ► Use lubricating paste (A) sparingly and apply to threaded parts and the sealing ring.

► Tighten firmly. Recommended tightening torque: 25...35 Nm. Depends on the lubrication, the seal and the pressure load! Too much torque may impair the seal and lead to the sensor being damaged. If the sealing area is damaged: replace the adapter. 6 Set-up ► Before set-up check the tank or pipe for ingress resistance. ► Perform a pressure test with screwed-in dummy plug or sensor. ► Set-up of the sensor: → Operating instructions of the sensor.
