Process connections
The sensor is supplied to order, with or without pre-installed process connections. Pre-
installed process connections are firmly secured to the sensor by 4 or 6 hexagonal-headed
bolts.
The sensor may need to be supported or additionally secured depending on the
application and pipe length. In particular, it is absolutely essential to secure the sensor
additionally if plastic process connections are used. An appropriate wall mounting kit can
be ordered separately as an accessory from Hauser.
Seals
• In the case of metal process connections, the screws must be tightened securely. The
process connection forms a metal connection with the sensor, which ensures a defined
compression of the seal.
• In the case of plastic process connections, observe the maximum torques for lubricated
threads: 7 Nm (5,2 lbf ft); always insert a seal between the connection and the
counterflange.
• Depending on the application the seals should be replaced periodically, particularly if
molded seals are used (aseptic version)! The interval between changes depends on the
frequency of the cleaning cycles, the cleaning temperature and the medium temperature.
Replacement seals can be ordered as an accessory.
• For "PFA" lining: additional seals are
always
required (Promag 200).
