UMSITRPDS3-1 

INTRODUCTION 

This installation guide contains an outline of the procedures to be used to mechanically and electrically 
install Siemens SITRANS

TM

 P Series DSIII Pressure Transmitters. It is intended for use by experienced 

installers. Detailed information needed to bench test, install, configure, calibrate, and service a transmitter 
is included in User’s Manual UMSITRPDS3-1. Detailed product specifications are also included in the 
User’s Manual. 
 
The User’s Manual is supplied on the Siemens Process Instrumentation User Manual CD, included with a 
Series DSIII transmitter shipment. To access UMSITRPDS3-1 on the supplied Siemens Process 
Instrumentation User Manual CD, perform the brief procedure below. The manual is in Portable 
Document Format (PDF). A link for downloading the free Adobe Reader is provided.

Product Description 

SITRANS P Series DSIII transmitters provide reliable, accurate, stable, and cost-effective measurement 
of differential, absolute, and gauge pressure and liquid level. 
 
Figures 1 through 4 show the basic transmitter models and optional mounting bracket kits. Transmitter 
dimensions are provided in the User’s Manual. Measuring cell construction determines a transmitter’s 
physical dimensions and mechanical installation. Note that a given sensor construction can involve one or 
more measurement methods, as shown in Table 1.
