SAMSON has added the new TROVIS SAFE series to its range of positioners. The positioners marketed under the registered trademark TROVIS SAFE have been optimized for use with on/off valves in safety-instrumented systems and are certified to comply with SIL requirements. The valve diagnostics including partial stroke testing integrated into the positioners allow faults in pneumatic shut-off valves to be detected at an early stage and malfunctions, such as a seizing up of the valve, to be avoided. Numerous options are available to start the partial stroke test manually or automatically. The integrated diagnostics are the basis for round-the-clock valve monitoring: test data are saved in the positioners and the condensed state according to NAMUR Recommendation NE 107 indicates the valve status at a glance. The parameters ready configured for shut-off valves and the discrete analysis of the current signal especially for on/off valves round off the benefits of the TROVIS SAFE series.
The positioners with on-site operation can communicate using the HART® protocol. Intrinsically safe and flameproof versions are available.
