Installation Process - FineTek SIS2 Operation Manual

10.2 Installation process

 Make sure that the sealing surface is clean before installation and remove the
protective cover only when installing. If the sealing surface is damaged, replace
the device.
 The distance between the front probe and the silo wall has to be over 30mm in
order to prevent the sensibility to be influenced.
 Install or weld the adapter sleeve onto the container/pipe.
 For installation of the tri-clamp, follow the relevant provisions for additional
installation steps.
 Attach the seal to the sensor through the thread lock sleeve. The seal must be
correctly positioned and locked. Close the gap between the sensor and the
adapter sleeve end face.
 An inappropriate seal may cause installation errors.
- The seal is too large: It may be squeezed out, causing shear damage and
unable to seal.
- The seal is too thin: The seal is insufficiently compressed between the
sensor and the adapter sleeve. Leakage may occur.
Standard

Apply a little grease in the thread to help locking.

Lock the sensor into the adapter sleeve and tighten with a tightening torque
of 20...25 Nm.

After locking, the seal must not be exposed or cut off. It must be compressed
at least 1/4 wire diameter or more than 0.3mm to ensure sealing.
