VERVIEW
Electronic transmitters series SST5X are apparatus which use a piezoresistive sensor for pressure
/ temperature / level measurement and transmit a current signal (4÷20 mA) proportional to the
variable measured. The series SST5X is composed by the following types:

ANDATORY
!
The external local indicator to connect to the transmitter “SST5X with output for local
indicator” shall be a simple apparatus or an apparatus subject of a separate certification

TTENTION
!
This manual does not contain information concerning all type of Transmitter 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“.
