Sitrans P320/420 digital pressure transmitters feature remote safety handling via Simatic PDM (process device manager). To save time during safety integrity level (SIL) commissioning, it lets operators access transmitters from the control room, rather than requiring them to manually program each individual device throughout a facility. Both pressure transmitters have an increased proof test interval compared to other devices, with testing periods of up to 15 years rather than every two, which cuts maintenance costs.
