2.4 Installing the Promag H sensor
Depending on the order specifications, the sensor is supplied with or without ready-mounted
process connections. Mounted process connections are fixed to the sensor with 4 or 6
hexagonal-headed bolts.
"
Caution!
Depending on the application and length of the pipe, the sensor may have to be supported or
additionally secured. The sensor must be secured if using plastic process connections. An
appropriate wall mounting kit can be ordered separately from Endress+Hauser as an accessory.
2.4.1 Seals
When mounting the process connections, make sure that the seals in question are free from dirt
and centered correctly.
"
Caution!
• The screws must be securely tightened in the case of metal process connections. Together
with the sensor, the process connection forms a metal connection that ensures defined seal
compression.
• The seals should be replaced periodically depending on the application, particularly if molded
seals are used (aseptic version)! The intervals between seal replacement depend on the
frequency of the cleaning cycles and the fluid and cleaning temperatures. Replacement seals
can be ordered as an accessory.
2.4.2 Welding the sensor into the pipe (weld nipples)
"
Caution!
Risk of destroying the electronics! Make sure that the welding system is not grounded via the
sensor or transmitter.
a. Secure the sensor with a few welding points in the pipe.
A welding jig suitable for this purpose can be ordered separately as an accessory.
b. Release the screws on the process connection flange and remove the sensor, including the
seal, from the pipe.
c. Weld the process connection into the pipe.
d. Mount the sensor back into the pipe.
In doing so, make sure the seals are clean and correctly positioned.
Note!
• When welding is performed correctly with thin-walled pipes carrying food, the seal is not
damaged by the heat even when it is mounted. It is recommended, however, to
disassemble the sensor and seal.
• For the disassembly work, it must be possible to open the pipe approx. 8 mm (0.31 in) in
total.
