PROline Promag 53 3 Installation
Endress+Hauser 27
Assembly with ground disks (1" to 12" / DN 25 to 300)
Depending on the application, e.g. with lined or ungrounded pipes (see Page 56), it
may be necessary to mount ground disks between the sensor and the pipe flange for
potential equalization. Ground disks can be ordered separately as an accessory from
E+H (see Page 97).
"
Caution:
• In this case, when using ground disks (including seals) the total fitting length
increases! Dimensions → Page 146.
• Hard rubber lining → install additional seals between the sensor and ground disk
and between the ground disk and pipe flange.
• Polyurethane lining → only install additional seals between the ground disk and pipe
flange.
1. Place the ground disk and additional seal(s) between the instrument and the pipe
flange (Fig. 16).
2. Insert the bolts through the flange holes. Tighten the nuts somewhat but are still
loose.
3. Now rotate the ground disk as shown in Fig. 16 until the handle strikes the bolts.
This will center the ground disk automatically.
4. Now tighten the bolts to the required torque (see Page 28)
5. Connect the ground disk to ground → Page 58.
