Alignment Of Sitrans Sl - Siemens SITRANS SL Operating Instructions Manual

Alignment of SITRANS SL

Both sensors of the SITRANS SL have to be aligned such that the laser beam from the
transmitter hits the photo detector in the receiver. To facilitate this both transmitter and
receiver have a spherical surface incorporated in the flanges. The alignment is done by
adjusting the position of the flanges on this surface by means of two adjustment screws and
thus pointing the axis of symmetry - see following figure.
