Type of probe mounting
• When installing in plastic tanks, the nozzle must have at least DN50/2". The appropriate flange
must be used as the process connection.
• For nozzles up to 450 mm high, select the length of the centering rod appropriate for the nozzle
height when using rope probes.
• Use spring washers (1) (see Figure below).
!
Note!
It is recommended to retighten the flange bolts periodically, depending on process temperature
and pressure. Recommended torque: 60...100 Nm.
• After mounting, the housing can be turned 350° in order to simplify access to the display and the
terminal compartment.
≤ 450 mm / 18 "
The coupling nut must be tightened using a torque of 5 up to a maximum of 10 Nm when installing
the FMP41C in the universal adapter ("Welding boss for adapter 43 mm" → ä 73).
