| Siemens announces pressure transmitter for Profibus PA SIL2 safety functions | ||
|
||
 ATLANTA, October 23, 2006 – The Sitrans P DSIII digital pressure transmitter from Siemens Energy & Automation, Inc. is the first Profibus PA device available on the market that is designed for SIL2 safety shutdown in accordance with IEC 61508/IEC 61511-1. In the Sitrans P DSIII, a Profisafe driver has been added to the standard pressure transmitter enabling the fail-safe transfer of the measured values via Profibus. The measure values, which are determined several ways and compared internally, include pressure, absolute pressure, differential pressure, flow and level. Through Profibus PA, the Sitrans P DSIII is connected with a Simatic S7400 controller that triggers a safe shutdown, such as the Sipart PS2 PA electro-pneumatic Profibus-PA positioner. In the case of "redundant/diverse" design, measuring circuits up to safety level SIL3 can be established. With the Simatic PDM configuration tool, Sitrans P DSIII is started up as a regular Profibus-PA device and then the Profisafe safety functions are activated. The files required for this, such as the "Device Description" and the "Safety Manual", are available on www.siemens.com/sitransp.
