1. General information
1.1 Purpose of this document
This safety manual for functional safety is concerned with the model S-20 pressure transmitter only as a component
of a safety function. This safety manual applies in conjunction with the documentation mentioned under chapter
1.2 “Other applicable instrument documentation”. In addition, the safety instructions in the operating instructions
(article number 14043170) must be observed.
The operating instructions contain important information on handling the model S-20 pressure transmitter. Working
safely requires that all safety instructions and work instructions are observed.
Application range
The model S-20 pressure transmitter has been designed for universal application in machine building and plant const-
ruction. The operator has to ensure a regular change in pressure and with that a proportional change in output signal.
The pressure transmitter, due to the selected performance level, does not provide a diagnostic function to detect a
static signal due to an instrument failure.
1.2 Other applicable instrument documentation
In addition to this safety manual the operating instructions (article number 14043170) and the data sheet PE 81.61 are
applicable for model S-20.
