proportional to the variable measured. The series SST7X is composed by the following types:
SST70
Displacer level transmitter
SST71
Smart Float Level Transmitter
SST72
Electronic temperature transmitter
SST75
Absolute or relative pressure transmitter
SST76

TTENTION
!
This manual does not contain information concerning all type of Transmitters or all different
installation and/or working and mounting solutions. For more information or for particular
problems not considered in this manual, please address to our technical office.
The warranty period is the one contemplated in our general servicing conditions. This warranty
is neither increased nor restricted by the contents of this manual.
This Transmitter has to be installed and used only by qualified persons who have first checked
the correctness of supply voltage so that both in standard working conditions and in presence of
damages of the plant or of any part of it, no dangerous voltage can reach the Transmitter. As
the Transmitter can be utilized both with high pressure values and with aggressive media it
must be considered that an incorrect use of it could bring even serious damages to people and
things. A correct and safe working needs an adequate transport, stock and mounting other than
an appropriate maintenance service. So it is necessary for the people handling these
Transmitter to have knowledge and experience in mounting, servicing and working and to have
title to do their job with reference to “Safety Standards“.
